ChannelID (1st byte) of QSP packet is not needed. Drop it and instead use 32bit salt key for authorization:
Instead of initializing CRC with 0 at the beginning of frame encoding and decoding, initialize it with 32 bit secret key used to bind both TX and RX. This way, 1 byte will be saved and packets will be protected by crc only
