IoT Projects with Arduino Nano 33 BLE Sense: Step-By-Step Projects for Beginners

I bought this book mainly for the AI chapter. Unfortunately this chapter is unusable as it refers to a file called Gesture Training.ipynb which should be found under the source code for the book. However the source code is not available under the book's product page on GitHub, as claimed on the book information on the page before the contents. Basically without this source code the chapter on AI is useless and unusable. The rest of the book is very basic and certainly not worth the price I paid for it.
