Hi all wanting to reach out to see if anyone else has had this issue. We have been using the Alta X for our LiDAR surveys. after about 5 auto mision flights it randomly did not want to arm and sent an error ; "Preflight fail: Compass #0 uncalibrated". We then wanted to perform a compass calibration but when we tried to initait it then QGC hit us with another error- "Mag 0 (ID 3081) no matching uROB devid". we tried to restart everything multiple times and we continued to get the "Mag 0 (ID 30...etc" eventually it allowed us to do a compass calibration succesfull, but then when trying to arm the drone again we got hit with the "Preflight fail: Compass #0 uncalibrated error again. We tried and tried again but eventually had to give up. anyone else experience this? @Freefly any advice? cheers
