Meshtastic Bridge

Connect two distinct radio Meshtastic networks using TCP.

WARNING: Traffic is sent insecure using TCP. Use a VPN to secure traffic between the nodes

Requirements

• Python3
• Two Meshtastic devices:
  • Local LOCAL_NODE_ADDR The IP address or Serial devPath (micro USB cable needed for serial access) of a local Meshtastic device
  • Remote REMOTE_NODE_ADDR The IP address of a remote Meshtastic device

Refer to https://meshtastic.org/docs/settings/config/wifi#wifi-client to configure a Meshtastic device to use wifi and expose a TCP address

Setup

Run the following steps to download and install the software locally

$ git clone https://github.com/geoffwhittington/meshtastic-bridge.git
$ python3 -m venv meshtastic-bridge
$ cd meshtastic-bridge
$ source bin/activate
$ pip install -r requirements.txt

Turn on the Bridge

In the meshtastic-bridge directory run the following - replacing BRIDGE_DISTANCE_KM, LOCAL_NODE_ADDR and REMOTE_NODE_ADDR with the proper values:

BRIDGE_DISTANCE_KM=0 LOCAL_NODE_ADDR=/dev/ttyUSB0 REMOTE_NODE_ADDR=182.168.86.123 python main.py

Bridge Options

• BRIDGE_DISTANCE_KM Do not bridge messages from nodes that more than BRIDGE_DISTANCE_KM kilometers from the local Meshtastic device. Default 0 (no limit)
