Meshcore
MeshCore is a multi platform system for enabling secure text based communications utilizing LoRa radio hardware. It can be used for Off-Grid Communication, Emergency Response & Disaster Recovery, Outdoor Activities, Tactical Security including law enforcement and private security and also IoT sensor networks.
Joining
Are you interested in joining the mesh? You will need to purchase a LoRa radio from the MeshCore Supported Devices list. Outside of the mesh, we are most active on our public Discord Server including a whole section for MeshCore discussions.
Roles
- Companion: Intended role for end-user devices which provide an interface via the phone or web app (via BLE or USB)
- Repeater: Nodes in this role extend the range of a MeshCore Network. It does NOT forward or retransmit every packet it receives.
- Room Server: Turns the node into a simple BBS server for sharing posts. Room servers store message history on them and push the stored messages to users. Room servers allow roaming users to come back later and retrieve message history.
- Room-Peater: A combination of Room Server and Repeater roles. Install the Room Server then enable repeater role via the "set repeat {on|off}" command.

Repeaters
Meshcore works well with neighborhood repeaters, increase the range and reliability of Puget Mesh by setting up your own repeater. The Repeater Setup Guide walks you through the process.
