MeshCore

Meshes

ScotMesh has both Meshtastic and MeshCore — radio messaging systems for small LoRa devices. It lets people send short messages across a volunteer-run network without needing mobile coverage, Wi-Fi, or the internet. Carry a small companion node in your pocket, connect it to your phone, and you’re on the mesh.

The remainder of this document focuses on Meshcore.
