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,
According you previous description, could you confirm the following information you provided:
1. keep the sensor stationary;
2. record gyroscope data 1 minute;
3. Repeat step 2 four times to record the gyroscope data. Do you mean you close gyroscope and open it before you re record gyroscope data?
If your question is urgent, you can provide an email address and we will contact you.

1 & 2 are correct
3: We repeat 2 for four more times. Yes. Close as in we turn it off and then again reinitialize it after turning it on every time

Hi JCAeron,
During record sensor data, you close/reopen gyroscope, do you add enough delay time until gyroscope become stable before you record data?
