wrong accel readings with cheap GY-91

[vinmicgra]

Im trying to use the cheap GY-91 module which should include bmp-280 and mpu-9250.

BMP-280 works fine but the mpu-9250 is acting strange. When I use "accel-calibration.ino" to check accel data the accelerometer shows working values for all 3 axis but those are way too high.

I think the values are exactly 8192 times too high (2^13). Is there any way to divide all accel readings by (2^13)?

`Ready to make measure. Don't move the accelerometer and wait... Starting measure... accel=(45.55667, 283.25000, 8223.03027) Standard deviation = 186.76228
