We’ve come across a sporadic issue with yaw stabilisation on a copter with a Navio 2 and Raspberry Pi 3 onboard.
We’re using an external HMC5883L that was calibrated with the onboard calibration method using Mission Planner. All other compasses are turned off.
As you can see on the video the copter tries rotating itself on the 3:35 and 4:20, although no commands were given to do so (RCIN.CH4 is constant all the time). It seems to me, these rotations corelate with ATT.DesYaw in the log.
It’d be greatly appreciated if anybody could take a look.
