    BNO055 Reads Inaccurate Acceleration Values When Configured to 16G Mode

    BNO055 Reads Inaccurate Acceleration Values When Configured to 16G Mode

     I'm building a flight computer for a high power rocket and I need to read at least 11Gs. To achieve that I configured my BNO055 to work at 16G but when I did that my BNO accelaration values became way too inaccurate. It senses up to 0.9 m/s^2 when idle and senses up to 1G when moved just slightly.

     On software I first change BNO055's mode to Gyro&Acc mode. Then I write "0x13" to BNO055 ACC Config register. Do I need to do additional things? I don't think it shouldn't go this inaccurate when configured to 16G.

    Note: It works fine at 4G configuration. Also I can't use fusion modes, it's not recommended on rockets.

    Hello Altay,

    Did you have log data when you tested it?

    Hello Altay,

    We set ACC range to 16G with BNO055 shuttle board, couldn't reproduce your feedback.

    Could you let us know how to reproduce your feedback?
