Flashing & Configuring a Companion Node

Flashing a Companion Node

The easiest way to flash a MeshCore-supported node is by using the official web flasher tool in Google Chrome:

MeshCore Web Flasher

Only Google Chrome supports the serial connection required for flashing.

Steps:

  1. Plug your device into your computer via USB.
  2. Open the MeshCore Web Flasher.
  3. Select your device hardware
  4. Select the firmware choice Companion Radio (Bluetooth)
  5. Click Enter DFU Mode.

  7. Click Flash to install the MeshCore firmware.

Note: Sometimes after erasing, the flash step may fail. If this happens, refresh the page, click Enter DFU Mode again, and then click Flash to retry.

Configuring a Companion Node

After flashing, follow these steps to set up your companion node:

  1. Pair the node with your phone or computer (usually over Bluetooth).
  2. Give the node a descriptive name (e.g. your callsign, location, or handle).
  3. Set it to the Ottawa frequency defaults: 910.525 MHz / BW: 62.5 kHz / SF7 / CR5.
  4. Test by sending a message in the Public channel.
  * If a repeater hears you, the message will show Heard X Repeats instead of just Sent.  

Tip: You may wish to disable Message Settings → Auto Reset Path. This isn’t required, but many users find it helpful when testing links that aren’t fully stable, as it prevents the path from constantly resetting.
