BNO055 yaw initial value behavior

[jspear16]

Hello all,

I have a (hopefully) simple question. I looked over the datasheet and could not find a direct answer to my question so I figured I would ask you. I am trying to test the yaw readings for the BNO055 and noticed during my tests, the beginning of the data included these rather strange spikes (see the depressed region of the graph below). This entire dataset included 10000+ points, and the rest are fine, however, this initial behavior is odd and something we are trying to figure out and qualify. It appears to be some sort of searching algorithm, but I frankly have no idea what would be causing this behavior, so I was hoping someone may be able to provide an adequate explanation. 

Thank you!

Hello jspear16,

When the accuracy is 3, the data is credible. Could you check the curve of data accuracy?
