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:
Connect to your Meshtastic device over Bluetooth, USB serial, or Wi-Fi.
Radios on firmware older than 2.5.14 stay connected and lead straight to the firmware update, which is now required. Back up and restore the app database. Failed messages resend in place. Reactions get their own notification channel. Radio settings open without a radio, and search lands on the setting. Site Planner coverage runs on the phone. Many stability fixes.
