    BNO055 Axes Order

    Hello!

    I am new to BNO055. I have a BNO055 mounted vertically with:

    • X axes pointing downwards
    • Z axes pointing towards observer horizontally
    • Y axes pointing towards observer's right

    What should be the Axes Order to obtain Euler angles? The default ZYX works well when the sensor is placed horizontal where Z is the heading, Y is the pitch and X is the roll. But unfortunately when I mount the sensor in vertical position (as required by the application), I am unable to obtain usable values.

    Pardon my ignorance but in NO_FUSION mode I have tried all 12 combinations and observed that for GYRONLY mode:

    • Calibration status is always s0 g0 a0 m0
    • All angles never change from zero values despite movement in all coordinate directions

    If I do not need accelerometer and magnetometer data and want only gyroscope data shouldn't I use NO_FUSION and GYRONLY? Your advice will help me to use the sensor in the correct intended manner. Thanks.

    Kind regards.

    Hello baqwas,

    If you want to get Euler angles, suggest you config sensor to IMU or NDOF mode.

    Thanks! Will do as advised. Again thanks to other threads, I've been doing some more reading and definitely will make progress.

    Kind regards.
