Data format
- Byte = 1 Bit Message Start Indicator + 7 Bit Payload
- Only one message (checksum + command) can be sent per UDP package
- Max UDP package size 1472 bytes including checksum; fragmented by simple cutting (even inside a command)
Checksum
2 Bytes - sum of scrambled message bytes; MSB first.
Checksum has to be send before message.
