We are using the BHI260AB in our product. We get acceleration data and angular velocity from BHY2_SENSOR_ID_ACC_RAW_WU and BHY2_SENSOR_ID_GYRO_RAW_WU virtual sensors. The max sampling frequency has been set to 800hz in the Firmware. and we set the sensor frequency to 400hz with bhy2_set_virt_sensor_cfg function.
The raw acceleration and angular velocity from BHI260AB is very smooth. At 400 hz, we expected to see some noise due to the vibration.
The question is : Does the bhi260ab do internal filtering on the acceleration and angular velocity signal? If yes, what is the frequency? Could you provide a corresponding table to show the filter setting for different ODR?
Thanks a lot

The IMU part of BHI260AB can refer to BMI160.
BHI260AB cutoff frequency will vary according to ODR. The relationship between cutoff frequency and ODR could be referred in BMI160 data sheet.
