+Bluetooth Card10 Service
+==========
+
+.. warning::
+    The specification is still work in progress
+
+The Card10 Service implemented a direct Hardware access of the card10.
+
+BLE Service
+-----------
+
+The current draft uses following service specification:
+
+- Service
+
+  UUID: ``0000f000-2342-2342-2342-234223422342``
+
+- light sensor characteristic:
+
+  UUID: ``0000f0f0-2342-2342-2342-234223422342``
+  read
+
+- Vibra characteristic:
+
+  UUID: ``0000f10f-2342-2342-2342-234223422342``
+  write
+
+- Rockets characteristic:
+
+  UUID: ``0000f110-2342-2342-2342-234223422342``
+  write
+
+light sensor characteristic
+---------------------------------
+
+The light sensor characteristic makes it possible to read the current value of the light sensor by receiving a ``uint16``.
+The range of this sensor is between 0 (``0x0``) and 400 (``0x9001``).
+
+- reading of ``0x0e00`` means **14**
+
+vibra characteristic
+---------------------------------
+
+The vibra characteristic makes it possible to let the card10 for given millisecound in a ``uint16`` vibrate.
+
+- One secound: ``0xe803``
+
+Rockets characteristic
+---------------------------------
+
+The Rockets characteristic makes it possible to address every three rockets.
+Just write there three byte array, one for evey rocket.
