Hi ilcnet,
1. If you want to run BSEC algorithm, you could use BME688 shuttle board or the board with BME688 designed by you. 2. If you would like to use BME AI-Studio, you need to get BME688 dev kit. 3. After you download BSEC2 software from https://www.bosch-sensortec.com/software-tools/software/bme688-software/, you could find integration guide from "BSEC_2.0.6.1_Generic_Release_04302021\integration_guide" folder, and see if the output you need is already in the list.
4.For example code, you could refer "BSEC_2.0.6.1_Generic_Release_04302021\examples\bsec2\examples\basic_config_state" or more example on github: https://github.com/BoschSensortec/Bosch-BSEC2-Library/tree/master/examples/generic_examples
