BMP581 Temperature compensation

[Damon]

Hi,

I've got two BMP581 sensors. One reports the correct pressure (see right hand plots), the other does not and has a strong correlation with temperature (see left hand plots).

Is there any way to debug the temperature compensation parameters?

The datasheet describes checking the NVM CRC but I can't read the NVM memory using the functions in https://github.com/boschsensortec/BMP5_SensorAPI

Thanks for any help you can provide!

Hi Damon,

Thanks for your inquiry.
The BMP581 has integrated compensation function internally and does not require compensation outside the chip.
Did you design or purchase the hardware for your BMP581? In what environment were your two BMP581 tested?
