so how does bluetooth work?
Discussion
Oh no no, I don't know the technical answer to that. It's like how does a remote control work. I also don't know. It's a short distance thing, um, yeah. Waves.
ok so you can only chat with people within your wavelength? how short is short distance?
I think it's like 300m or something. But I don't know. If you are 300m from someone and theres a chain further and further out, I believe you are connected(?) maybe
Apparently it's similar to firechat which was used in the Hong Kong protests when the internet was down.
sounds pretty cool
