Sensor fusion and absolute position?
Has anyone out there implemented absolute position using sensor fusion with the MetaWear chips? Do you have a prefered library? Anything for Android in particular?
I am not aware of any such work. Until recently, it was not possible to do sensor fusion as we just put a megnetometer on the board.
Thanks Eric. From what I understand (which is very basic), you can still do sensor fusion without a magnetomter, but it's not as good as having three sensors to work with (i.e. 9DOF vs 6DOF).
We've decided to use the BNO055 which does on-board sensor fusion tied in via I2C. That unfortunately is presenting its own set of challenges:
