BNO055 : accuracy of the magnetometer

[ciramor]

Hi,

I am using a BNO055 with arduino uno. After calibration of the BNO055, I test it by set the sensor on the specific position (my reference), I read especially the azimuth (my interested value) and after I move the BNO by oscillated right/left, and/or up/down during few minutes. Then I set again the BNO to the beginning specific position. I expect to have same value on Roll/Pitch/Yaw. I can see that it is not the case. Somebody can explain why ?

thanks in advance

regards

Can you please provide more data? Which working mode you are using, what values you are reading, how much error you are seeing, etc.

The best would be a datalog of the BNO055 raw data, output data and calibration statuses.

In general we would expect the error to stay within ~2,2,5 degrees (tilt, roll, heading)
