Unofficial Web Bluetooth remote for Canon cameras
This is a Web Bluetooth-based implementation of remote control for Canon EOS cameras based on prior reverse engineering work by Ian Douglas Scott.
Disclaimers
First of all, this project is in no way affiliated with Canon and you use it at your own risk.
It mostly works, but I'm having an issue where, once camera goes to sleep, it can't connect again and needs to be unpaired, power-cycled & paired again - still not sure whether that's just my camera or the implementation should be doing some kind of regular pings to keep connection alive.
