I see you got smartaudio to work .
My vtx got hot and melted when I get the replacement I have serial rx1 turned on and skipped a line and have the tbs smart audio as a choice is there some other thing I have to do to make it work?

In Betaflight choose 'smartaudio v2' on that RX port, that's it. Once I got the softserial figured out for this board, it worked from there.
