    BMI270 Gyro issue :: drift in zero-rate offset

    BMI270 Gyro issue :: drift in zero-rate offset

    A random change is observed in the bias values of BMI270 Gyro data in its stable state. This change in the zero-rate offset values is random and can be seen on all X, Y, Z axes. Also I have used the latest BMI270 API version. BMI270 is tested on different boards to ensure that the issue is not board specific. The Gyro data output remains to be erratic. I am using only the Gyro for my application. Hope this is not the expected behaviour.

    Any explanation on why is it so? Has anybody else observed this issue with BMI270?

    Graphs attached below. Hope to get a reply back soon.

    Hi JCAeron,

    Can we know detailed information about how you tested it?
    What is the corresponding relationship between axis 1,2,3 and axis x, y, z?
    Are run1-run5 axis data obtained at different times? If so, is the sensor always stationary when you record axis data?

    Hi @BSTRobin 

    The device is mounted on a static platform while taking logs. All three axis data is recorded at the same time. The time difference between each run is 1 minutes and the device is turned OFF during this time. Axis 1, 2, 3 corresponds to sensor axis x, y, z respectively
