This developer-led video covers everything from setup to configuration. Recommended if you prefer a guided overview before diving into the steps below.

Step 1: Flash Your Device

  1. Visit the MeshCore Web Flasher page using a Chrome-based browser.
  2. Connect your LoRa-compatible device to your computer via USB.
  3. Select your board from the dropdown list on the flashing page.
  4. Choose the firmware labeled “Companion Bluetooth” to connect via Bluetooth or “Companion USB” if connecting to a computer with a USB cable and using the Web Client.
  5. Click Connect, then Flash and wait for completion.
Note: Some devices require holding a reset or boot button when plugging in to enter flash mode. You may also need to install USB drivers for your specific board before your computer can detect it. Visit your board manufacturer's site for drivers.

Step 2: Connect via Bluetooth

  1. Install the MeshCore Companion App:
  2. Ensure Bluetooth is enabled on your phone.
  3. Power on your device and open the Companion app.
  4. When your device appears in the list, tap it to connect via Bluetooth. Enter the pairing code on your device's screen
  5. Wait for confirmation that the connection is successful.
Note: If your device doesn’t appear, try restarting both your phone and the device. You may also need to reflash if pairing fails repeatedly.

Step 3: Configure for Canada

  1. In the app, tap the Settings icon. It will look like a gear.
  2. Scroll down to Choose Preset and select Canada.
  3. This automatically sets:
    • Frequency: 915 MHz
    • Bandwidth and power settings compliant with Canadian laws
  4. To join our local room, return to the home screen, tap the three dots in the top right corner, tap Add Channel and scan the QR code at the top of this page using Menu → Add Channel → Scan QR Code.
  5. Save your settings and reboot your device if prompted.
Important: You must configure your frequency and encryption settings to match your local network or your messages will not be relayed.

Step 4: Test and Explore

Return to the Channels screen in the Companion app and try sending a message by tapping on the Public channel and typing a message. If you are within range of another node or repeater, your message will be transmitted across the mesh network.

Experiment with different rooms, check packet statistics, connect to room servers, and explore how your node connects to others.
