Join the mesh

Get a radio, flash it, and send your first message. Anyone can join.

What you need

Anyone can join the mesh. All it takes is a LoRa radio board, a USB cable, and a few minutes.

The flasher installs MeshCore from your browser onto these boards:

Buy the 915 MHz (US) version of whichever board you choose, and attach the antenna before you power it on. Transmitting without an antenna can damage the radio.

Steps

  1. Open the flasher in Chrome, Edge or another browser with Web Serial support, plug the board in with a data USB cable, and pick your board.
  2. Choose a role. A Companion is the one you carry and pair with your phone. A Repeater is for a high, powered spot and relays for others.
  3. Install. The newest build is selected by default. The Build menu lets you pick an older version.
  4. Pair with the app. Install the MeshCore app on your phone, connect to the radio over Bluetooth, and check that the radio settings match the ones on the firmware page.
  5. Send a message. If you are in range of other MeshCore nodes, they will start to appear.

Help it grow

The mesh is a volunteer effort, and it grows with every radio that joins. A repeater helps most from a high spot with power and a clear view in every direction. Check that its radio settings match the rest of the mesh before you put it up.
