Hi, I connected a FrSky R-XSR receiver to a Omnibus F4 Pro V3 flight controller using SBUS protocol for control and SmartPort for the telemetry.
For the telemetry I connected uninverted SmartPort signal from R-XSR to Serial1 TX on the flight controller and I set these parameters on Ardupilot:
SERIAL1_PROTOCOL = 10 (FrSky SPort)
SERIAL1_OPTIONS = 4 (Half Duplex)
The telemetry works, but when I discover new sensors on the transmitter I find only the GPS.
I can see the GPS coordinates, but nothing else.
To check that it is not a hardware problem I flashed betaflight on the flight controller and with this firmware I can see many others sensors on telemetry, like speed, altitude, accelerations…
What I have to do to see more data on Ardupilot telemetry?
