    Re: BNO055 losing calibration

    But the magnetometer is the most hardcore sensor to calibrate (to my eyes).
    When the magnetometer calibration status goes to zero because of external distortion, is it easier to get it back to status 3 than it would be calibrating from scratch?
    In the author’s case, a robot boat is only able to perform planar motion, will it be able to recalibrate to 3 with only planar rotation ?

    I think you might be already see this video for BNO055 calibration.

    Even we support the fast magnetic calibraion,  the planar rotation is not able to achieve the calibration level 3 from level 0.  

     

    How did you make the calibration?  if the major magnetic distortion is not coming from the lake,  you can try to calibrate the sensor nearby the final position to make the fusion lib know about the magnetic environment.  

     

    In the other word,  when you do the system design,  you should keep the magnetic sensor away from the magnetic material as well as the big current lines.

    I gave up trying to use it... It's not stable unless it's sitting perfectly still.
