+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``
+
+- Vibra characteristic:
+
+  UUID: ``0000f10f-2342-2342-2342-234223422342``
+  write
+
+- Rockets characteristic:
+

+
+vibra characteristic
+---------------------------------
+
+The vibra characteristic makes it possible to let the card10 for given ms in a ``uint16`` vibrate.
+
+- One secound: ``0xe803``
+
+Rockets characteristic
+---------------------------------
+
+The Rockets characteristic makes it possible to address every (three) rockets.
+Just write there two byte array.
+

+- Enable Rocket 3 with 50% lightness: ``0x027f``
+
+Single led characteristic
+---------------------------------
+
+This characteristic makes it possible to address every single led.
+Just write a byte array ``uint18`` address of led and three ``uint8`` for the rgb color.
+
+Dataformat:
+
+====== ===== ===== =====
+ 0-1     2     3     4
