I was trying to do something similar with esp32+lora development boards. And I got like 3km range in my city so it was great ! But then I wanted to make it a ""usable"" thing and started getting stuck on designing a protocol that allows multiple senders at the "same time". I thought of doing a time slice system since this whole project was inspired by a telecommunications class I had, but the issue would be that people you would need to know in advance the number of slices and your assigned one and also the devices would have to be synchronized, and I really wanted to make it dynamic, do anyone can just turn on their thing and it does a sort of handshake until everything works. If anyone has pointers It'd be very appreciated, I found out about meshtastic.org while doing this project too. In the end this was my first embedded experience, and my first embedded with Rust, so at least I got something "working" but I would love to make something as "usable" as this post.
