Hello, I am looking at using the BNO055 IMU to obtain heading in NDOF mode and am curious how auto calibration works. Is auto calibration writing its values on a regular basis (i.e. every minute) or is it triggered by events? How does it know to write to the offsets in the registers? How often would this be done? I understand auto calibration cannot be disabled, but I was wondering if there was some sort of way to work around this. Is it possible to write to the calibration offset registers at a regular basis to prevent auto calibration or perhaps be able to restore the desired calibration offset? The reason I am concerned about auto calibration is because I plan to use the IMU fixed on a moving vehicle. Once it is mounted it would be impossible to go through the initial calibration procedure. The best I could do would be to drive the vehicle in figure-eights. Any thoughts or feedback would be greatly appreciated. Cheers, Laura
