Frequent axis dropout from BMM150 on the BMI270 shuttleboard

Hi,

 

I've been experimenting with the BMM150 sensor that comes with the BMI270 shuttleboard and have noticed a really odd issues.  On one axis (normally z) the reading keeps dropping to zero.  I've attached a screenshot from Dev Desktop.

Also the ranges are way off - z axis ranges from 20 to 130, x from -40 to 50 and y from -30 to 70.  There doesn't seem to be anyway of calibrating this built into Dev Desktop or am I missing something?

 

Cheers,
Chris
