    Hi Team, 

    I am working with BHI160B imu and reading orientation data continuously for our application using STM32-L053R8.

    Along with orientation data, we also read the Accuracy of measurement. But when I read the calibration status(Accuracy of measurement), It got fluctuated between 3 (calibrated) and other values. worrying about the data captured when status(Accuracy of measurement) got fluctuated.

    Clarification Required:
    Are BHI160B calibrators always-on by design -(calibration will always run in the background)? or

    Do I need to re-calibrate again everytime? If yes, Could you please recommend some workaround to avoid frequent re-callibration?


    Any help would be very thankful

    Hello vamshi,

    I am facing the same issue of the Magnetometer calibration value changing when reapplying after a power cycle, Did you find any solution for it?

    Hello Bosch team,
    Can you please provide a solution for the above issue with the magnetometer?

    Hi Saicharan,

    No, I did not find any soulution to that. I think we need to write calib values every time when accuracy changes. I am also waiting for the reply from BOSCH team. If you find the info on this please let me know.

    Thank you,
    vamshi.
