BerryGPS-IMU v4 Not Getting Compass value

[Hardik Raval]

Hi Ozzmaker Team,

We just perchased one BeryyGPS IMU V4 and Started Work with Raspberry Pi 4 Model B and Load the Code step by step of Compass like shown below

1. Basics

2. Tilt Compensation

3. Calibration

But I don’t get the 360′ degree complete in 4 angle i get like

89-> 249->297->348
so diffrent is 101 -> 160 -> 48 -> 51 and the correct should ber 90 angle.

Please help us out of this problem.

Thanks & Regrads
