BME688 AI Application fails

[bsec]

HI,

I created 2 AI models, one for coffee similar to the youtube video and one for foul vegetables. Both algorithms produce probabilities > 95%. I checked the configuration file output from AI Studio with 3 different applications: Arduino ESP32 (exact the ino example in BSEC 2.0), ESP32 in eclipse development environment and on a STM32 nucleo platform, all linked with libalgobsec.a (depending of the MCU used). In every test I get the result Gas Estimate 1 (normal air -> 1.0). Whatever I do I never get any probability > 0.0 in Gas Estimate 2, even if probe within the Coffee glas or in the fouled vegetable container. Any experience with BME688?

For sampling I used BME 688 dev kit board (8 sensors) on Adafruit HUZZAH32

Thanks for the reply. But its not possible to access this video, please upload to youtube or so, then its possible for us to see. Thanks

Hello Falkenbergo,

You could refer the video in BME AI-Studio tool. See my previous reply.

Hello, I collected data using the BME688 Development Kit, then I trained and evaluated the algorithm and exported it as an .aiconfig file, similar to the video. Now, I want to connect the BME688 Dev kit board with the LoRa-E5 Development Kit (with STM32WLE5), using I2C to test the sensors with STM32. How do I integrate the .aiconfig file into my CubeIDE project?
