BMX160 Mag Data ajustment

[JayLynkz]

Hi, 

I would like to know how to ajust the Mag Data out of a BMX160 device. After ajusting the accel. and gyro data with the appropriate conversions from LSB units, I don't find any conversions for the mag data. I linked pictures of what I get, which turns around 100 for z and around -30 for x and y. 

Am I right to be expecting something around 50 in an axis (earth's magnetic field) and close to 0 for the 2 remaining axis ?

Thanks for your help!

BMX160 has built in BMM150 inside sensor. 

So you can refer to the BMM150 API on Github with function: "bmm150_aux_mag_data". 

Within this funciton,  you can find how to convert the register output to uT.

This solution is accurate. 

I would add that we should follow the advice at the end of this topic to get the correct z values. 

Thank you !
