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?
Using the following settings;
SERIALx_OPTIONS= 7 (invert TX/RX,Half Duplex)
