Today I had my first trouble with my mavic pro, which otherwise worked perfectly in the last 2 months.
About 2 minutes into the flight, the drone made strange roll movements left then right - at least according to the video, it was too high and I couldn't exactly see what it was actually doing but it seems this is roll movement beyond gimbal limit?. Right then, these error messages popped up:
1. Warning: Compass failure. Exit P-GPS mode.
2. Warning: During flight, working IMU encounters heading exception, please switch to atti mode if craft behave abnormally
The drone switches to Atti mode and stayed in it for about 45 seconds, during which it obviously started to drift. Luckily, there was not much wind up there. After those 45 seconds, during which I started to descend and fly back, the GPS was restored. I waited for some time, and continued to fly absolutely normally without any incidents whatsoever during the following 15 minutes long flight. Then I changed location and had another long flight on the same day, again flawless.
Still, wondering if this is just a compass calibration due? I did an IMU calibration once a couple of weeks ago and don't think I need to repeat?
Here's the video, from 0:16 you can see where it started.
