If you read the BME AI software after saving the config it states cintact this forum for an example of using the config and running inferences using the bsec software. Where are these examples for instance the coffe or not config and sample arduino code.
Also how to use a single sensor rather that the board to generate the initial readings,
Re: BME688 inference examole using the bsec 2 library
Currently, it can only run on demo hardware and software. If you have a project to develop, you can contact your local distributor, and apply for the relevant software for single sensor in your project.
