+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs

+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behaviour.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ * In practice the use of this function shall be as follows:
+ * - Call bsec_sensor_control() which returns a bsec_bme_settings_t struct.
+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to

+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behaviour.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.

+ * In practice the use of this function shall be as follows:

+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to

+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when

+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ * The bsec_sensor_control() interface is a key feature of BSEC, as it allows an easy way for the signal processing
+ * library to control the operation of the BME sensor. This is important since gas sensor behaviour is mainly
+ * determined by how the integrated heater is configured. To ensure an easy integration of BSEC into any system,
+ * bsec_sensor_control() will provide the caller with information about the current sensor configuration that is
+ * necessary to fulfill the input requirements derived from the current outputs requested via
+ * bsec_update_subscription().
+ *
+ * In practice the use of this function shall be as follows:
+ * - Call bsec_sensor_control() which returns a bsec_bme_settings_t struct.
+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to
+ * bsec_do_steps() to perform the signal processing.
+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.
+ *
+ *

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * determined by how the integrated heater is configured. To ensure an easy integration of BSEC into any system,

+ *
+ * In practice the use of this function shall be as follows:
+ * - Call bsec_sensor_control() which returns a bsec_bme_settings_t struct.
+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to
+ * bsec_do_steps() to perform the signal processing.
+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * determined by how the integrated heater is configured. To ensure an easy integration of BSEC into any system,

+ *
+ * In practice the use of this function shall be as follows:
+ * - Call bsec_sensor_control() which returns a bsec_bme_settings_t struct.
+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to
+ * bsec_do_steps() to perform the signal processing.
+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behaviour.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.

+ * In practice the use of this function shall be as follows:

+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to

+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and

+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Main signal processing function of BSEC

+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behaviour.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ * determined by how the integrated heater is configured. To ensure an easy integration of BSEC into any system,
+ * bsec_sensor_control() will provide the caller with information about the current sensor configuration that is
+ * necessary to fulfill the input requirements derived from the current outputs requested via
+ * bsec_update_subscription().
+ *
+ * In practice the use of this function shall be as follows:
+ * - Call bsec_sensor_control() which returns a bsec_bme_settings_t struct.
+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to
+ * bsec_do_steps() to perform the signal processing.
+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.
+ *
+ *

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and

+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * @brief Main signal processing function of BSEC

+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behaviour.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+/*!
+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Main signal processing function of BSEC

+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behaviour.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ * determined by how the integrated heater is configured. To ensure an easy integration of BSEC into any system,
+ * bsec_sensor_control() will provide the caller with information about the current sensor configuration that is
+ * necessary to fulfill the input requirements derived from the current outputs requested via
+ * bsec_update_subscription().
+ *
+ * In practice the use of this function shall be as follows:
+ * - Call bsec_sensor_control() which returns a bsec_bme_settings_t struct.
+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to
+ * bsec_do_steps() to perform the signal processing.
+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.
+ *
+ *

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behaviour.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.
+ *
+ *
+ * @param[in] inputs Array of input data samples. Each array element represents a sample of a different physical sensor.
+ * @param[in] n_inputs Number of passed input data structs.
+ * @param[out] outputs Array of output data samples. Each array element represents a sample of a different virtual sensor.
+ * @param[in,out] n_outputs [in] Number of allocated output structs, [out] number of outputs returned

+ * determined by how the integrated heater is configured. To ensure an easy integration of BSEC into any system,

+ * necessary to fulfill the input requirements derived from the current outputs requested via
+ * bsec_update_subscription().
+ *
+ * In practice the use of this function shall be as follows:
+ * - Call bsec_sensor_control() which returns a bsec_bme_settings_t struct.
+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to

+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals

+ *

+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the

+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * determined by how the integrated heater is configured. To ensure an easy integration of BSEC into any system,
+ * bsec_sensor_control() will provide the caller with information about the current sensor configuration that is
+ * necessary to fulfill the input requirements derived from the current outputs requested via
+ * bsec_update_subscription().
+ *
+ * In practice the use of this function shall be as follows:
+ * - Call bsec_sensor_control() which returns a bsec_bme_settings_t struct.
+ * - Based on the information contained in this struct, the sensor is configured and a forced-mode measurement is
+ * triggered if requested by bsec_sensor_control().
+ * - Once this forced-mode measurement is complete, the signals specified in this struct shall be passed to
+ * bsec_do_steps() to perform the signal processing.
+ * - After processing, the process should sleep until the bsec_bme_settings_t::next_call timestamp is reached.
+ *
+ *
+ * @param [in] time_stamp Current timestamp in [ns]
+ * @param[out] sensor_settings Settings to be passed to API to operate sensor at this time instance
+ *
+ * @return Zero when successful, otherwise an error code

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initalization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialised due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same

+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * within the same time period as they are read. A sequential provision to the library might result in undefined

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC

+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().

+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs

+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.

+ * @brief Main signal processing function of BSEC

+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests

+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().

+ * within the same time period as they are read. A sequential provision to the library might result in undefined

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.
+ *

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC

+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.

+ * @brief Main signal processing function of BSEC

+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests

+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.
+ *
+ *
+ * @param[in] inputs Array of input data samples. Each array element represents a sample of a different physical sensor.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.
+ *
+ *
+ * @param[in] inputs Array of input data samples. Each array element represents a sample of a different physical sensor.
+ * @param[in] n_inputs Number of passed input data structs.
+ * @param[out] outputs Array of output data samples. Each array element represents a sample of a different virtual sensor.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.
+ *
+ *
+ * @param[in] inputs Array of input data samples. Each array element represents a sample of a different physical sensor.
+ * @param[in] n_inputs Number of passed input data structs.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.
+ *
+ *
+ * @param[in] inputs Array of input data samples. Each array element represents a sample of a different physical sensor.
+ * @param[in] n_inputs Number of passed input data structs.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.
+ *
+ *
+ * @param[in] inputs Array of input data samples. Each array element represents a sample of a different physical sensor.
+ * @param[in] n_inputs Number of passed input data structs.
+ * @param[out] outputs Array of output data samples. Each array element represents a sample of a different virtual sensor.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.
+ *
+ *
+ * @param[in] inputs Array of input data samples. Each array element represents a sample of a different physical sensor.
+ * @param[in] n_inputs Number of passed input data structs.
+ * @param[out] outputs Array of output data samples. Each array element represents a sample of a different virtual sensor.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * @brief Main signal processing function of BSEC
+ *
+ *
+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is
+ * returned for an output only when a new occurrence has been computed. A sample of an output signal is returned only
+ * once.
+ *
+ *
+ * @param[in] inputs Array of input data samples. Each array element represents a sample of a different physical sensor.
+ * @param[in] n_inputs Number of passed input data structs.

+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * Processing of the input signals and returning of output samples is performed by bsec_do_steps().
+ * - The samples of all library inputs must be passed with unique identifiers representing the input signals from
+ * physical sensors where the order of these inputs can be chosen arbitrary. However, all input have to be provided
+ * within the same time period as they are read. A sequential provision to the library might result in undefined
+ * behavior.
+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
+ * virtual sensors where the order of the returned outputs may be arbitrary.
+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *
+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
+ * they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
+ * result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
+ * of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.

+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.

+ * - The samples of all input as well as output signals of physical as well as virtual sensors use the same
+ * representation in memory with the following fields:
+ * - Sensor identifier:
+ * - For inputs: required to identify the input signal from a physical sensor
+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
+ * - Time stamp of the sample
+ *

+ * @brief Interfaces of BSEC signal processing library
+ *
+ * ### Interface usage
+ *
+ * The following provides a short overview on the typical operation sequence for BSEC.
+ *
+ * - Initialization of the library
+ *
+ * | Steps | Function |
+ * |---------------------------------------------------------------------|--------------------------|
+ * | Initialization of library | bsec_init() |
+ * | Update configuration settings (optional) | bsec_set_configuration() |
+ * | Restore the state of the library (optional) | bsec_set_state() |
+ *
+ *
+ * - The following function is called to enable output signals and define their sampling rate / operation mode.
+ *
+ * | Steps | Function |
+ * |---------------------------------------------|----------------------------|
+ * | Enable library outputs with specified mode | bsec_update_subscription() |
+ *
+ *
+ * - This table describes the main processing loop.
+ *
+ * | Steps | Function |
+ * |-------------------------------------------|----------------------------------|
+ * | Retrieve sensor settings to be used | bsec_sensor_control() |
+ * | Configure sensor and trigger measurement | See BME680 API and example codes |
+ * | Read results from sensor | See BME680 API and example codes |
+ * | Perform signal processing | bsec_do_steps() |
+ *
+ *
+ * - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
+ * re-initialization to continue processing.
+ *
+ * | Steps | Function |
+ * |----------------------------------------|-------------------|
+ * | To retrieve the current library state | bsec_get_state() |
+ *
+ *
+ *
+ * ### Configuration and state
+ *
+ * Values of variables belonging to a BSEC instance are divided into two groups:
+ * - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
+ * configured before use with a customer specific configuration string.
+ * - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
+ * is necessary to maintain previously estimated sensor models and baseline information which is important for best
+ * performance of the gas sensor outputs.
+ *
+ * @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
+ * the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
+ * library state shall be stored in non volatile memory so that it can be loaded after system reset.

+ * @brief Subscribe to library virtual sensors outputs
+ *
+ * Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
+ * See ::bsec_virtual_sensor_t for available library outputs.
+ *
+ * Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
+ * (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
+ * will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
+ *
+ * The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
+ * important functions. It allows to enable the desired library outputs. The function determines which physical input
+ * sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
+ * When this function returns with success, the requested outputs are called subscribed. A very important feature is the
+ * retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
+ * group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
+ * outputs is requested.
+ *
+ * @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
+ *
+ * The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
+ * Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
+ * - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
+ * - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
+ * - Identifiers are unique values defined by the library, not from external
+ * - Sample rates must be provided as value of
+ * - An allowed sample rate for continuously sampled signals
+ * - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
+ *
+ * @note The same sensor identifiers are also used within the functions bsec_do_steps().
+ *
+ * The usage principles of bsec_update_subscription() are:
+ * - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
+ * - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
+ * are ignored. At the same time, a warning is returned.
+ * - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
+ * already disabled outputs do not have to be disabled explicitly.

+ * - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
