Hi,
thanks, ArduRover is running again after deleting APMrover2.stg. Upgrade is not working again, but I ihink I did it before. If try to run the upgrade again, I get apm-navio2 is already the newest Version. But it is not possible to calibrate the compass. By the way I see only one (compass 1). Further more the Mag calibration stops at 99%. Live calibration sometimes with success but Offsets like 369,722,271. We did now compass calibrations for hours and realized that sometimes after a try with Mag calibration the direction is wrong from 90 to 180 degrees. Missing 2nd compass and so on, is it possible that we have a defective board?
