Hey,

I am trying to set up a fixed plane with ELRS(CRSF Mavlink). I have set the correct parameters according to the ExpressELRS documentation, and I am having a weird issue,

when I open QGroundControl and connect the USB to the Nomad Module, its losing the bind to the Receiver.

When I use the Ardupilot software and Mission planner everything is working.

When I use PX4 Firmware and Mission planner as A GCS Software, it’s also working

I run out of ideas, I will appreciate any help.

Thanks

I am also facing the similar issues. People do suggest Mission Plannar

However, try to SBUS and connect with external RF connection keeping with SBUS as a option.

What PX4 version is this? And can you link to the instructions you followed?

Sounds tricky! Maybe check QGroundControl’s settings or try updating it—since it works in Mission Planner, the issue is likely there.
