RC Telemetry - Only getting GPS Sensor

Hey All,

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)
  • RSSI_TYPE =3

Arm the plane/ardupilot and it will work and show all the sensors.
Without arming it will only discover GPS sensors.
