During last two weeks I continued to work on ESP32 part of this project. I needed to figure out how notification system works internally (could not make it work properly) and has to check the source code of the Arduino BLE library. In fact it's a very thin wrapper around functions provided by ESP IDF framework and I have tried to run some examples from there. Worked really good and I have rewritten the whole project without Arduino framework. The footprint of the application became 30% smaller with the same functionality.

So, at the moment ESP32 advertises itself as FIDO2 device, handles BLE connection and receives commands from the browser. I was able to process GetInfo command and respond with device's capabilities.

Next step would be to process MakeCredential command and create new credential for the user. It's more complex and I assume it'll take few weeks to complete.
