Meshtastic offers a text messaging service that operates without internet, satellite, or cellular connections, using radios to send and receive messages and GPS coordinates. It's designed for ease of use, allowing anyone to communicate in areas without cellular coverage or as a backup communication method.
Utilizing LoRa (Long Range) technology, Meshtastic connects nodes (small, battery-powered radios) within signal range, forming a mesh network. Messages hop from node to node, reaching recipients even without direct line-of-sight, thanks to the mesh's retransmission capability. Security is maintained through encryption, ensuring that only intended recipients can read messages.
Getting Started:
- Choose a Node: Select a LoRa node compatible with your region (915MHz for North America, 868/433MHz for Europe). Popular choices include the HelTec ESP32 LoRa V3 and the Seed Studios SenseCAP T1000-E.
- Install Meshtastic: Flash your node with Meshtastic software using instructions from flasher.meshtastic.org.
- Download the App: Install the Meshtastic app on your device to pair with the node and join the mesh.
- Join a Mesh: Connect with existing nodes in your area or start your own mesh network. Engage with local mesh groups via channels like LongFast for community interaction.
