protocol software. Users familiar with hardwired packet networks may consider the 32 message bytes per
packet limit quite small. Packets sent by low-power wireless systems are kept deliberately short to improve
performance where on-channel burst interference and low signal-to-noise conditions are often
encountered.
The packet structure is given above. It uses a 4 byte preamble, 2 byte sync word 0xE2E2, a 1 byte
TO/From address (default 2/2), the message type (RF cmd, host cmd, RF msg), the data payload, and a
Frame Check Sequence (FCS) or CRC.
