MPU9250 heading is slowly drifting
#20
I have exactly the same problem with the MPU9255 sensor. Since the previous version of Pypilot, without Pypilot support, was updated to the beta that already incorporated pilot support, the MPU is no longer stable. In my case the calibration does occur but the values do not remain stable. Pitch, roll, heel and heading all start to vary every few seconds and become totally useless. I tested it with a clean Openplotter installation from yesterday January 13th. The MPU works fine with the previous backup but there is something in the new version of pypilot or some of its components that fails with the MPU9255.. 

Being able to download the older version for those of us who don't need pypilot support could be a solution for now. Unfortunately once a new part of openplotter is updated it is not possible to go back to the previous version and if something goes wrong we get stuck.
