How to setup the RFD900x TXMOD with Pixhawk 2.1?

I have the RFD900x TXMOD bundle. I have installed it in a rover with Pixhawk 2.1. I can see the telemetry through the TXMOD Wifi, but I cannot see the reception of the PPM radio signal. I cannot activate the radio controls on the Mission Planner screen. Could someone help me with this please? Thank you very much for your time.

@Julio_Durand, were you able to get your radios working? I am going through the same setup and I have PPM working, though I’m having trouble getting telemetry working through the TXMOD wifi, maybe we can exchange notes?

Hi! Just getting started a new project with ArduRover and having a similar issue…
