Meshtastic

Meshtastic is a decentralized wireless off-grid mesh networking LoRa protocol.

[1][2] The main goal of the project is enabling low-power, long-range communication over unlicensed radio bands.

It is designed around exchanging text messages and data in off-grid environments, with potential applications in IoT projects where a decentralized communication system is needed without existing infrastructure.

[5][6][2] Meshtastic uses hardware development boards, like ESP32 and nRF52840, that support LoRa and BLE communication technologies, along with GNSS receivers.

These devices enable seamless mobile app connectivity via Bluetooth or Wi-Fi, allowing long-range message retransmission across a mesh network using LoRa transceivers.
