Control your Canon Camera wirelessly

I am not a Canon shooter but I welcome really any open source efforts on this front; this is one area of tech where open source is really held back by various vendors' intransigence, API and protocol shenanigans (I'm looking at you Sony)

This is related, but not wireless, and works only for the Powershot series of cameras:

It is used for DIY book scanners.

This is kinda cool, but it's similar in function to the canon connect app which feels a little superfluous.

Maybe it connects better - I have a 70d and the connection process is annoying. Iirc it's WiFi direct but you have to connect and manage it yourself, and your phone will get cross there's no internet and disconnect you every so often.

My main camera now is a 90d which uses Bluetooth to connect first and then setup WiFi. Much easier process that makes the app much more useful. Although I've actually got an "unleashed" device that uses usb and hdmi for control, lets you do ramped time lapses and connect multiple cameras. No live view, but I can connect to both the 90d and 70d very smoothly which is more useful in general.

Olympus (RIP) published open documentation of their command protocols, which are just HTTP endpoints with URL parameters.

someone make this for Sony Alpha please...

It is ridiculous that such simple functionality is locked up.

I wrote an iOS app like that, for Nikon cameras, many moons ago. It was a real pain, but I did get it working. The biggest issue, is the streaming video.

If they use PTP-IP, you can do quite a bit.
