Had my refreshed Mavic Pro flying for the first time, I keep getting compass error on and off mid-flight when it was 200m above the sea! Flew back, did a calibration, cured for that battery.

Then it happened again next battery I flew, and it went so bad that the drone went into atti mode for a few seconds this time, check the compass status immediately and it said “restart aircraft” for a few seconds, and back to normal... then as I fly back, the error still pops up randomly. I have no clue what’s going on..

Any suggestions would be very much appreciated.

Were you facing the camera full down at that stage? When you say refreshed Pro was this a replacement given to you by Dji? if yes I would recomend that you do a firmware refresh, cold imu recal, gimble recal and then a compass recal in an open field with no keys, watch or any sort of metal on you. or you could have taken off from a spot that had some sort of interference that stayed with your drone

That would scare the hell out of me - glad you returned it safely   

It looks like the whole flight was fraught with compass and speed errors. According to data it looks like it was jumping between GPS and Atti mode, although the graph only shows a switch from GPS to Sport Mode. Something is up, you had plenty of satellites and a strong GPS reception.

The program was developed and created by a member of this forum, I believe he is currently working on a new version and will most likely make it available again once he is done. Great contributor and outstanding member here.

Thanks QuadKid for the information.
Do you know when he will have the new version?
Is it possible to get a copy of the original?
