Euler angles sudden shifts

kra

Hello, 

I am using the MetaWear Android app with the Meta Motion R with firmware v.1.3.3 to generate Euler angles. But I get some sudden drops or shift in the angles, like in the attached image at x=100, x= 210, x=243, x=276, etc. 

Why do I get these sudden drops? And what can I do to prevent them?

Thanks,

Klaus

How are you rotating the board?  Are the boards near any external magnetic fields?

Just by hand. The boards are not near any external magnetic fields!

What I mean is the exact motions you are doing.
