Hello BSTRobin, thank’s for your reply. I think I solved half of my problems concerning the sensor and BSEC. Just to make sure we have the same understanding: I connected the pi3g breakout board with BME688 sensor via a breadboard to the raspberry pi. I did a clean install of the pi3g Bosch bme68x-python-library and now can access values with get_bsec_data(). I used the pi3g library for the sensor (https://github.com/pi3g/bme68x-python-library) and the BSEC2 library from Bosch (integrated during install). The first initial install was done without BSEC, the second install with the BSEC library somehow didn’t install BSEC properly.The new clean install solved this problem. Now since I can read BSEC values I noticed that IAQ has a constant value of 25. Also other BSEC values seem to be static (e.g. co2_equivalent = 500, breath_voc_equivalent = 0.4999999..). I collected values for over 30 minutes without any changes. The non-BSEC values seem to be correct. Is there any way to speed up the calibration process – I think this process is responsible for not updating bsec values. And is there a way to store the calibration information and use it when the sensor gets powered up? I use a python-script to read values and write them to a mysql database. Thank’s again for your help!
