Pretty much, yes. It does have some tiny file share capability IIRC (don’t trust me on this) but it’s pretty much just an off grid text based communication platform you connect to with your phone and Bluetooth. Can be extremely long range depending on terrain (line of sight is important)
Can it be used to set up a grid with other people? Kind of like creating put own off-grid grid?
Isn’t that the definition of off-grid?
The routing is simple. Every node repeats everything it hears. A message goes out with a counter - defaults at 3, maximum 7. Every time it’s repeated the counter is decremented. At 0 it won’t be repeated any more.
You can DM nodes you’ve seen. You can create your own encrypted channels with a pre-shared key. You can link meshes over the internet through MQTT if you have an internet connected node on each mesh.
