I actually had the same issue. Using Cube Orange FD with PX4 and QgroundControl, I can’t find the parameter to change the RCIN protocol. The various suggested params are… simply not there.
I didn’t follow up on it really, as I have many other receivers and normally use the Ardupilot firmware with Mission Planner. This was a FrSky R-XSR receiver using ACCST with green light for binding but no RCinputs in QGC
But I’d still like to know where to change the RCIN setttings in PX4/QGC, even though it seems to autodetect without issue most of the time.
I’m a little perplexed here. The COM_RC_IN_MODE is just for setting RC only, Joystick only, RC or Joystick etc.
I rigged up the setup that I had an issue with again. It’s an R-XSR with ACCST firmware and I get no RC input even with a green light and RSSI signal confirmed. If I flash the R-XSR with ACCESS firmware and bind, then everything is fine.
Is there no setting for CubeOrange PX4 to manually set the RC protocol?
(Sorry to hijack the poster question but it’s the same issue)
