No idea. Do the individual byte counts seem OK? Maybe you have set a high
pass filter or something inadvertently.

Hi Kris,
I´m setting the sensor to those settings after reset. The accel only
changes its values when I move the device. There is no recognition of
earth´s G, when I let one of the axes pointing to the ground, what I would
expect.. Just a bit fluctation around 0. gyro and magnetometer values seem
to be reasonable.
Do you have an hint for me, please?
