Use roll and pitch agles in 0-360 format: The roll and pitch values are provided as pos/neg angle values which causes problems in the vector calculation for the motion detection => changed the implementation to store the calibration data with a 180? offset. Also shift value by 180? before they are used for vector calculations.
