Problem with BNO055
I am using BNO055 sensor, RTK GNSS module and Raspberry Pi 4 to get the North heading. After fully calibrating and saving calibrated data to the Raspberry Pi, I still got the wrong heading angle. I have already bought 2 BNO055 sensors to check the result but their heading angle was varied. Then I tried applying EKF, but I didn't get the desired result. Does anyone have the same problem?
