I’ve got an ESP32 board sitting in a box somewhere that I’ve been meaning to get out and fiddle with. This has certainly piqued my interest.

Are there any good resources you could link to that you found useful when connecting to those kind of boards from Web APIs please?

On the device side I've used a lot of code from the CanAirIO project: https://github.com/kike-canaries/CanAirIO. I do want to switch my code to the NimBLE stack instead of the default bluetooth stack at some point - apparently it uses a lot less memory.

On the web side I don't currently have any good public examples, but the generic Web Bluetooth samples here are a good starting point: https://googlechrome.github.io/samples/web-bluetooth/

Maybe I'll write a proper blog on this if I get some spare time.
