BHI260AP Soft Iron Calibration matrix

[tonny1010]

Hi Bosch,

We are using BHI260AP + BMM150 in our product. We would like to get the 9dof quaternion  from the sensor.

The datasheet 13.3.3 said the BSX library can use the soft iron calibration matrix to improve the estimation accuracy. We have successfully read the 3x3 SIC matrix in 72 bytes from bhi260. Could you please provide more information about the SIC matrix ? For example, how is the SIC matrix value coded? LSB or MSB first? and what is scale? max and min of the value?

Thanks
