it turn out, that default configurations such as "FieldAir_HandSanitazer" does not work. i got working the BSEC output without Configuration step "envSensor.setConfig(FieldAir_HandSanitizer_config);"... maybe you had a better ideas. Anyways, i write to you because  , i have two doubts: 1. ON my custom board there is only one BME688, However if define this variable "#define BSEC_MAX_PHYSICAL_SENSOR  " to 1, i get only temperatures.. it work with 8 (fake) physical sensor... 2. IAQ values differs strongly, with other IAQ values.. the iaq-bme is alway for a while 50 an then  oscillates on values of 90~130 on a ventilated room(should be 50~90)..Question:IAQ-BME, can be calibrated  or readjusted... ...

Hi Robin,   this link ""BSEC 2.x Software" https://www.bosch-sensortec.com/software-tools/software/bme688-software/?" just point me to the Home page of the BME688. There, one find 3 repos and other appications... Could you be please be more precise.. i implemeted the BME68x-Library.. this is one of these repos (https://github.com/BoschSensortec/Bosch-BME68x-Library). This API is working on the tree microcontrollers.  I tried to replicate the example (https://github.com/BoschSensortec/Bosch-BSEC2-Library/tree/master/examples/generic_examples/basic_config_state) on a custom ESP32S3 (NOT arduino)....but i got stocked at the moment to load the configuration...  the size of the file bmeConfig and the size of the FieldAir_HandSanitizer_config are not compatible..that says this function ( bsec_set_configuration(config, BSEC_MAX_PROPERTY_BLOB_SIZE, workBuffer, BSEC_MAX_WORKBUFFER_SIZE);), which is not accesible  😞 ...

Hi Robin,   Thanks for the reply. the outputs of the BSEC, seems to be more adequate for air quality specifications. Nevertheless, when i check the repo(https://github.com/BoschSensortec/Bosch-BSEC2-Library), i see basically that   raw data from the api is saved on a SD card or printed out. Therefore  i wanted to know, how to do the conversion on the MCU  (no further handling of data on Host Computers) Anyways , you are right. I dont need to deal with the BSEC  library, if i can handle the raw data directly on the MCU. However, i have a doubt about  one raw value: gas_index from <data[i]->gas_index = buff[off] & BME68X_GAS_INDEX_MSK;> How is this parameter related to air quality?..or ... is it just a heater step index?    ...
