Hello i am currently working with the BNO055 driver api (version 2.0.6) that is provided by BOSCH.My sensor software revision is 3.11. I am having a bit of trouble calibrating the BNO055 sensor. No matter how long i try to calibrate the sensor the SYS_Calib status remains 0 however i am able to get the accel,mag and gyro fully calibrated. i heard that the sensor can still be used if accel,mag, and gyro all reach 3 and that its ok to ignore the sys status but i would like to confirm this. I would like to reuse the calibration profile but the offset values that i am seeing are all 0 except for the mag radius which is 480. I suspect that these offset values are mostly zero because the sys status that was not fully calibrated but i am not sure. I have also noticed that the system error code register is set to 5 which means that "Register map address out of range" as stated in the manual. The system error code register is always at a value of 5 after the bno055_init function and i am not sure why. I suspect that this might be the reason why the sys status wont change at all. I have another BNO055 sensor that is new and has the same software revision 3.11 and it works completely fine running the same code and the system error code register on the new one is 0. I would like to get my other sensor to work though because it used to work before and this problem only started recently. I am using the read template function from BOSCH's api with some added code to read the system error code register and calibration so its nothing special, i dont think the code is the issue as i have said before it works on the new sensor. Is there any thing i can do to fix the system error code value of 5? Thank you
