Make your own Meshtastic LoRa Node with our easy DIY guide. A complete step-by-step for building your customized mesh communication system
I donโt think I understand its purpose. Itโs a shared wireless communication network for text messages only? So, like, sms-only that is completely independent of the main grid?
Pretty much, yes. It does have some tiny file share capability IIRC (donโt trust me on this) but itโs 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?
Isnโt 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 itโs repeated the counter is decremented. At 0 it wonโt be repeated any more.
You can DM nodes youโve 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.
