Completes the service
definition sequence
If a connection exists values written to data multiplexer channel 2 will be sent to the
remote device. If no connection exsists, the last value written to a multiplexer
channel will be stored in RAM. In case a connection from or to a remote device is
established, the remote device will receive the last value that the application wrote
to channel 2. If the application did not write a value to the data channel yet, the
value of the characteristic is set to 0. It is recommended that the application sets
default data values for all characteristics immediately after registration of all
characteristics.
