    According to the datasheet the 3 dB cutoff frequency is always lower than for the other axes? Is there a particular reason for this? And is it possible to get unfiltered data?

    thanks

    Hi,

    BMX160 accel unfiltered data is at 1600Hz ODR and gyro unfiltered data is at 6400Hz ODR where you can get them through FIFO. You cannot have both at 1600Hz for both unfiltered data. Unfiltered data doesn't have aliasing problem. The internal low pass filter curves require NDA. Please contact your local sales person or field application engineer to get the NDA placed.

    Thanks.

    Hello..to initialize the sensor, you will first need to create a device structure. You can do this by creating an instance of the structure bmi160_dev. Then go on to fill in the various parameters
