Unfortunately it seemed to work at first, but after changing the sample rate (of the example file) from High Performance to ULP the gas resistance seems to be fixed again. Only things i changed: - sample rate to BSEC_SAMPLE_RATE_ULP - deleted BSEC_OUTPUT_RAW_GAS_INDEX, BSEC_OUTPUT_GAS_ESTIMATE_1, BSEC_OUTPUT_GAS_ESTIMATE_2, BSEC_OUTPUT_GAS_ESTIMATE_3, BSEC_OUTPUT_GAS_ESTIMATE_4 from the sensor list, because I don't need it for my project. Now Gas Resistance gets stuck at around 5000 ohms. Using direct readout (not by BSEC) is fine. Or using the high performance, but not suitable for the battery operated device. It's really a pity Bosch seems to not be fine with some lite version of an algoritm like Sensirion shares with its vocindex. Sensirion is not usable for the project because of the 1Hz recommendation.

Thanks for the reply! I already use this version (18.104.22.168). It’s strange the Adafruit lib works (except for the iaq index), bsec doesn’t. Please also consider the dropping iaq index by applying an ethanol aerosol in the room, where it should rise! Maybe i should therefore consider bsec 2. Only it’s unclear for me after downloading the v2 how to install in Arduino. Should i just replace the precompiled lib with the 22.214.171.124 one? The zip file seems to not be importable into Arduino, I didn’t found clear instructions how to import, maybe missed it. (Only reference to the old library instructions) Edit/Update -> After downloading the version 2 BSEC i unzipped everything and put the examples\bsec2 contents in the erased 'old' 126.96.36.199 directory. It works now!
