I wondered if each BME680 sensor has its own unique serial number written into its non volatile memory somewhere, e.g. together with its calibration data.
It would be helpful to be able to identify each sensor to assign collected measurement data after swapping devices or replacing them within our setup.
If there is some register providing this information, could you please share ist address to be read out?
I don't know how to identify each sensor as well by their own unique serial number.
Maybe each BME680 has its own unique serial number, but it has never been shared for external users, only for internal trace.
About pressure sensor or enviroment sensor, the different sensors have the different trim value, you can know them by the datasheet.
Recommend you to have a try to verify the trim value of BME680 to distinguish each sensor.
