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.

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.

Hi yohai i think there is a problem in wires that you use this code works with i2c wiring.regard

Wait I didn't understand what you wrote.

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