Answer Messages

In the answer message the source address is the address of the sensor (default value
0x80).The destination address (in this case 0x32) is the node ID of the node that has sent the
request. The priority is always 7 (0x07).
On each parameter message the sensor will send an answer with a code in the first byte of the
data bytes section.
Below an example for an "Answer Message" with node ID 0x80.
