It is left in an inclined surface (without any motion), then I realize that there was an offset. The angle offset is reduced when the inclined angle is reduced, so...

Of course, it is fixed in the surface, but a smaller inclined surface will produce a smaller offset in the angle.

I mean that I doubt on the calibration of the accelerometer. Why did the output angles deviate an amount (constant offsets) from its true value when I fixed it on...

Because the offset of the angles is varied depending on the inclined angle of the surface. So I just think that even I put in a slightly inclined surface, the...

@ccopot I have the same problem as you. Did you get a solution? It took much time to follow, but nowadays no one maintains this project!
