Inertial sensor heading swaying

All four of our inertial sensors randomly sway sometimes in the heading after calibration

The value in a video it took that I cannot post the sensor value will just slowly increase

Running latest firmware 1.0.9

You may have a problem with vibration skewing your inertial data.
There are a lot of posts on this topic as well.

But it does it when it’s stirring still right after calibration before any movement
