testing the effect of the temperature on BMI270 readings I noticed a strange behavior. I expected to see a drift on readings according to increasing temperature, instead I see many different steps, like if there is something acting internally to compensate the changing temperature.
I searched on the datasheet, but I have not found any explanation.
You can appreciate what I'm saying in the attached 30' plot of the Gyro value for the Z axis where also the temperature value is reported.
Any idea about what can be the cause of those steps?
PS the sensor was steady and I verified that nothing was acting on it while testing.
Solved! Go to Solution.

o_o, you've said that the "BMI085 is an order of magnitude more stable". I do not see this in the datasheets. Are you mistaken?
|Sensitivity temperature drift||0.02 %/K||0.03 %/K|
|Zero-rate offset change over temperature||0.015 dps/K||0.015 dps/K|
