After flashing and going though setup, when doing radio calibration message comes up saying “detected 0 radio channels”. Flashed Ardupilot and all channels work with both crossfire nano rx and frsky r-xsr.
Any idea what could be happening here? Code error? Really scratching my head on this one.
Unfortunately I don’t have an answer for you - I observed the exact same thing with PX4 firmware not working with the R-XSR receiver on the mRo Control Zero.
At some point in the recent past, mRo updated the Control Zero page to say “PX4 support is in process”: https://store.mrobotics.io/mRo-Control-Zero-F7-p/mro-ctrl-zero-f7.htm, so I suspect that it just does not work yet.
