Hi Sir:     Do you mean  accel, gyro and mag  raw data  or IMU mode or NDOF with FMC mode data differ from the last measured values while in calibration after loading the calibration file the values of system ?     Did you check their accuracy, which also have a value of 3?     If device was not moved, we ensure the environmental magnetic field has not been changed.     If these are all ok, you should compare the current accel, gyro and mag raw data and the last accel, gyro and mag raw data to know what happened.    ...

Hi Sir: Do you mean that you use 4.7.5 Slope / any-motion detection? I verified this feature, and maybe found the same phenomenon you said. I think it is normal, because in the temporary mode an asserted interrupt and selected pin are cleared after a defined period of time if you don't read int_status registers, you can browse BMA280 datasheet to know it more. Please see the 4.7.1 General features and Figure 6 in the datasheet. If you don't want the pin switches to low , you should choose latch mode. ... View more
