Experiencing an issue with the AI model freezing or becoming unresponsive #28

I am experiencing an issue with the AI model freezing when I give it to “smell” something different with the Wio Terminal and the Grove - Multichannel Gas Sensor v2. But just testing it in training mode works just fine. I haven’t found anyone who has this problem. I have recorded a video of this problem. I guess it does not have enough memory due to newer firmware on Wioterminal.

I have attached the video with this issue https://www.youtube.com/watch?v=hiUD3TPLzSI

Thank in advance

I am experiencing difficulties while conducting scent detection using the Wio Terminal and the Grove Multichannel Gas Sensor v2. During the training mode, the detection results do not match the expected outcome. It should detect "ambient (surroundings)" initially as there is no smell present, but it instead shows "coffee".

Furthermore, when I attempt to detect the scent of hand sanitizer containing alcohol, the result indicates "Whiskey", but the machine freezes when displaying the percentage (%) likelihood.

I would like to ensure more accurate scent detection results. Are there any suggestions or steps I can take to address these issues? Thank you.
