Command Format - Michael MBWBLUE Mode D'emploi

Command Format

The general format of the MBWBLUE communication is (all bytes hexadecimal):
01 FE LL CD [Data] CRC CRC
01 FE:
LL:
CD:
[Data]:
CRC CRC:
The CRC is calculated using the creator polynomial shown beneath:
X16 + X13 + X12 + X11 + X10 + X8 + X6 + X5 + X2 + 1
The CRC is calculated over all bytes of the command except the CRC itself (from the
first start sign to the last byte before the CRC).
Example code is listed below:
