Euler angles sudden shifts


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. image

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



  • 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.
