BHI160 plus BMM150 calibration procedure, if any

[carlosande]

In our application we are getting sensor output for both Game Rotation Vector and Linear Acceleration.

1-We are supposing the BHI160/BMM150 has the similar feature set as BNO055 and as demonstrated in the video (https://youtu.be/Bw0WuAyGsnY) procedure to calibrate it with BSX3.0. Can we apply the BNO055 procedure to BHI/BMM?

If not, otherwise, is there a procedure we shall apply to BHI/BMM to calibrate its sensors ?

2-The estimated accuracy is always output as zero for Game Rotation Vector, why is that?

3-Is the STATUS byte in Vector+ Data format related to calibration of physical sensors and automatic adjust of internal parameters of motion processor algorithms?

Hi Carlos,

Thank you for your post.

1. Yes indeed BNO055 and BHI160 are using more or less the same sensor fusion algorithm. Calibration procedure is the same
2. The BHI160 reports the accuracy in a different manner than BNO055, it is following the Android standard. Please refer to Android's documentation regarding this.
3. The STATUS byte in the Vector+ format is the same as you are used to with BNO055. Yes, the sensor fusion algorithm takes this into account when calculating hte sensor fusion.
