When trying to run the final sketch, I'm getting the following error:

Edge Impulse Inferencing Demo
Inferencing settings:

Any idea how to fix this?

It's pretty hard to follow this at the time of writing as Edge Impulse seems different and trying to work out missing bits is pretty hard.

I have been dealing with an ongoing error with de version 3.0: error: 'esp_i2s' has not been declared

Sorry for the inconvenience. Due to version updates, this tutorial may no longer work as expected, and you might need to make some adjustments to use it.

I had the same issue and wrote a tutorial on how to get around the problem:

hmm, maybe useful for all. This tutorial doesn't work anymore but I wrote an updated version that works (for now Aug 2025):
