I just found out about it. Open Source messaging. It seems intriguing although I'm not sure I would have much to do with it. I honestly can't find too much information about it except for the website and a few YouTube videos. I was just curious if anyone has had experience with it.
This Meshtastic, I take it? I haven't personally used it, but it sounds interesting! Not too surprising there's not much info about it though, as it does sound rather niche.
That's the one. I just ordered some stuff to try it out.
