    BNO055 "Self Test Failed" and "Fusion algorithm configuration error"

    Hi

    I am using the BNO055 with the Bosch api.

    On startup, in the CONFIG Mode, I get those errors: "Self Test Failed" and "Fusion algorithm configuration error"

    And when I load 9-DOF Mode, I get the same errors.

    If I reset the sensor, the "Fusion algorithm configuration error" does not show again, but the self-test still fails.

    Also, without doing calibration, and having the IMU placed still on the bench, the calibration results for Accel, Gyro and Mag always read 0x03 instantly after power-on, which is not realistic.

    I get the same response with more than one IMU.

    I am not sure what I am doing wrong.

    I attached the log from the IMU that I capture during startup

    any help ? thanks

    Hello Salam,

    Do you refer example code from github? https://github.com/BoschSensortec/BNO055_driver/blob/master/bno055_support.c

    Hi

    I only used the bno055.c and bno055.h library files in the same GitHub. I did not use the bno055_support.c

    thanks
