Revision history [back]

I am not sure I completely understand your question, but I don't think this will work if you want to check if there was a change by any exact amount. If you look at the IMU data you are streaming right now you will almost certainly see some noise even when the IMU is motionless. As a consequence you are unlikely to ever find that the orientation is exactly some angle; you would have to check that the angle was between some range.
