Gyro and Accelerometer calibration issue

I've been using calibration code example which works only for magnetometer. I did modify the code to perform calibration for gyro and accelerometer. Unfortunately, result of calibration always states (Accuracy Unreliable (0)). I followed BOSH guideline for gyro and accelerometer calibration, but no changes in accuracy reading were present.

Any feedback would be highly appreciated :)

Start by reproducing the calibration code example and documenting the difference between magnetometer calibration and the modified gyro and accelerometer behavior. Compare the observed accuracy readings with the BOSH gyro and accelerometer calibration guideline. Done means the affected sensors report reliable calibration accuracy rather than “Accuracy Unreliable (0)”.
