Hi I am currently trying to use the Bno055 sensor in a project where I need to find velocity relatively accurately for 30 seconds. I attempted to use the BNO055 in NDOF mode to get linear acceleration straight from the register this data however sees large amounts of drift due to inaccurate linear Accel readings. I checked the calibration status and all sensors and the system are reading 3. Is there any pointers someone may have on what I may be doing wrong. I am using the breakout made by adafruit for a school project and would appreciate any feedback greatly.
