Hi Digisolve, I setup a example code to demonstrate how to get calibration accuracy on MCU(STM32) for your reference. After you get calibration accuracy 3, test the performance and give feedback.

Hi Digisolve, Yes, you could get heading information from BHI260AP in DD2.0 like you did from the BNO055. After you load firmware successfully and set the following sample rate of accel, gyro, mag, you also need to set orientation sample rate. Set Sample Rate to 25Hz for Acceleromter Passthough(Non-Wakeup) Set Sample Rate to 25Hz for Gyroscope Passthough(Non-Wakeup) Set Sample Rate to 25Hz for Magnetomoter Passthough(Non-Wakeup) See pitch, heading, roll values:

Hi Digisolve, We saw your latest feedback in https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/BNO055-unreliable-calibration-amp-heading-readings/td-p/57796/page/3

Hi Digisolve， You could refer chapter 3.11.4: Multiply your floating-point matrix by the 14th power of 2 to get the matrix to be written into BNO055. Call this function to write SIC matrix. struct bno055_sic_matrix_t { s16 sic_0; /**< soft iron calibration matrix 0 data */ s16 sic_1; /**< soft iron calibration matrix 1 data */ s16 sic_2; /**< soft iron calibration matrix 2 data */ s16 sic_3; /**< soft iron calibration matrix 3 data */ s16 sic_4; /**< soft iron calibration matrix 4 data */ s16 sic_5; /**< soft iron calibration matrix 5 data */ s16 sic_6; /**< soft iron calibration matrix 6 data */ s16 sic_7; /**< soft iron calibration matrix 7 data */ s16 sic_8; /**< soft iron calibration matrix 8 data */ }; BNO055_RETURN_FUNCTION_TYPE bno055_write_sic_matrix(struct bno055_sic_matrix_t *sic_matrix);
