Today, I have two times "Compass error" caution. I have flown in the same location before, without issues. Today the caution came on both time, I was flying in the same spot and turning 360 degrees. I switch to ATTI and bring it down. I perform again compass calibration procedure and after take off, caution came on on the same spot and again, I was turning 360. height was about 40 meters. I checked the compass mod value during the caution, it was 1490-1550. Why it kick in compass error on the same spot on the air? Could it be my car cause interference, during compass calibration? On the video compass error came on 5:17 This was my first compass issue. Would it be good to perform IMU calibration, or is it pure compass issue? According to the manual, Phantom can return automatically home point in A-mode(if the home point was stored), have you test it?
