Meshtastic is an open-source, off-grid mesh networking project that lets
you send messages and view node locations over long distances without
cellular service or the internet, using inexpensive LoRa radio hardware.

Features include:

• Text messaging between nodes on the mesh network
• Encrypted channels for private group communication
• Node management and device configuration
• Works entirely offline — no internet required

Connect to your Meshtastic device over Bluetooth, USB serial, or Wi-Fi.
