Thank you Robin, I guess I overlooked this description from BSEC documentation. I have only one more question in regard to sensor calibration. I have noticed that one of the provided BSEC examples (for Arduino, namely) uses a "hand sanitizer" configuration data for its example. Does this mean that calibration data (given as an array of 1974 bytes) may be modified somehow to adapt BME688 to a specific gas or mixture of gases? Or is there a different approach to calibrate sensors to detect only a specific gas? If there is such approach, how is this done in practice? Luke
