Good morning, just a few comments and questions..
1) current 4bits for msgVersion and 4bits for hdrType. With 14
messages and some not implemented (suspend/resume/...) we have
little headroom in 4bits of hdrType. Shall I make the msgVersion
3bits and the hdrType 5bits?
2) the smallest interleaved FEC encoded msg is 30 bytes. With 8
bytes of data: a msgSpec, using RS(15,9) with 4bit symbols, and 4
symbol block interleaving, the smallest on the wire is 30 bytes.
Without FEC enabled is it 8 bytes.
3) when run to the end of hdrType room, we can add a jump tag and
have a second hdrType field as the 9th byte.
Again, the valid document link is:

Thank you,
robert
