I have a Matek F765 and R9M connected to UART - TX4 (Serial 6) and using FPORT. I am able to control my surfaces so the radio link is working however when viewing sensors on my transmitter, I only get GPS.
Any ideas? I havent updated OpenTX for a while so I’m wondering if it is that?
In that case, sorry I have no solution. If GPS sensor is discovering, that means Fport settings and other config is ok. I would probably check other board.
