    Re: Calculate co2 and h2s with Bme688

    Hi ilcnet,

    BME688 Development-Kit was used to record sensor RAW data and verify the trained algorithm.
    BME AI-Studio Software was used to train BME688 sensor data and generate configuration file.
    You could get document and software from the link: https://www.bosch-sensortec.com/software-tools/software/bme688-software/
    Follow the guide to start your work.

    Hi, I'm trying to run the example code you mentioned, and I got the following error:

    BME68X error code: -2

    Do you have any idea why I get this error?

    I'm using the Nicla Sense Me tool, which has the BME688 sensor.

    Wait I didn't understand what you wrote.

    Ok, there is probably a problem with the wire, but how do I fix it?
