  • Try specifying Serial1 as the port. I'm doing this to data to a bluetooth LE module over the rx/tx pins.

  • What you're seeing is a very common problem in orientation sensing. As I understand it, the built-in DMP is fusing only the gyro and accelerometer. The magnetometer must be used for stable orientation on all 3 axes, which is the art of 9-DOF sensor fusion. This and many other relevant issues are well described in this wiki.

    As strider points out, there was support for 9DOF fusion in the previous razor board's library (which was in fact a fork from the repo by the author of that wiki), though it's mysteriously absent from this new version... it would be great to see this added!

No public wish lists :(
