hi,
I am a little bit newer here. If my question looks stupid  , I am sorry.

In HC-07, the compression of UDP port are:
P: 00: 16 Source port + 16 Destination port
01: 16 Source port + 8 Destination port
10: 8 Source port + 16 Destination port
11:4+4

If both source and destination ports can be compressed to 8 bits , but the P
field must be set 01 or 10?

why not separate the source port from destination port encoding like :
011 C S D
Then it can carry the ports for both 8bits.
