MeshCore-EastMesh

MeshCore-EastMesh originates from the upstream MeshCore project:

• https://github.com/meshcore-dev/MeshCore

Credits to Scott Powell / Ripple Radios and the MeshCore contributors for the original firmware and project foundation.

EastMesh firmware builds for MeshCore, with MQTT repeaters, WiFi companions, and simple release downloads for supported boards.

This repository keeps the upstream MeshCore firmware intact and adds an EastMesh layer on top for packaging, release automation, WiFi-enabled companion builds, and MQTT-enabled repeater builds.

What This Repo Adds

• *_repeater_mqtt firmware targets with:
  • native WiFi
  • MQTT over WSS with JWT auth
  • optional local HTTPS config panel on supported ESP32 targets
• *_companion_radio_wifi firmware targets for WiFi-connected companion devices
• EastMesh-specific release workflows and versioning on top of upstream MeshCore releases
• docs and release guidance for EastMesh users instead of the full upstream MeshCore docs set

Releases

Prebuilt firmware is published on GitHub Releases:

• https://github.com/xJARiD/MeshCore-EastMesh/releases

For flashing guidance, including when to use .bin vs -merged.bin, see:

• docs/releases.md

The custom firmware flasher site is:

• https://flasher.eastmesh.au/

Install uv

This repo uses uv for Python tooling and runs PlatformIO through uv run.

Official install docs:

• https://docs.astral.sh/uv/getting-started/installation/

Common install methods:

macOS and Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Homebrew:

brew install uv

Windows PowerShell:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Common Repo Usage

Install tooling:

uv sync

List available build targets:

bash build.sh list

Build a single target:

uv run pio run -e heltec_v4_repeater_mqtt
uv run pio run -e heltec_v4_companion_radio_wifi

Build with release-style version metadata:

export FIRMWARE_VERSION=v1.14.1
export EASTMESH_VERSION=v1.0.1
bash build.sh build-firmware heltec_v4_repeater_mqtt

Flash a target:

uv run pio run -e heltec_v4_repeater_mqtt -t upload --upload-port /dev/tty.usbmodemXXXX

Open a serial monitor:

uv run pio device monitor --port /dev/tty.usbmodemXXXX --baud 115200

Build docs locally:

uv run --group docs zensical serve
uv run --group docs zensical build

Key EastMesh Features

MQTT Repeater Additions

• hardcoded broker support for:
  • eastmesh-au
  • letsmesh-eu
  • letsmesh-us
• WSS transport at /mqtt
• JWT auth using the device identity
• CLI controls for:
  • WiFi credentials
  • WiFi powersaving
  • board battery reporting on supported targets
  • MQTT endpoint enablement
  • MQTT packet and raw publishing
  • owner public key and email
  • local web panel enablement

Local Web Panel

On supported *_repeater_mqtt ESP32 targets, the repeater can expose a local HTTPS config panel over WiFi.

Features include:

• password-gated access using the existing repeater admin password
• allowlisted CLI execution
• grouped quick actions
• light and dark themes
• optional disable via set web off

Recommended use is initial setup and occasional troubleshooting. On MQTT repeater deployments, disable the panel again when finished if you want maximum MQTT heap headroom.

Some constrained targets disable the panel to stay within flash limits. For example, Xiao_C3_repeater_mqtt builds with WITH_WEB_PANEL=0.

Companion WiFi Additions

*_companion_radio_wifi targets now support persisted WiFi rescue commands:

• open a serial monitor at 115200 baud
• reboot the device
• long-press the user button within the first 8 seconds after boot to enter CLI Rescue
• wait for ========= CLI Rescue =========
• send the commands from the serial monitor

These rescue commands are only available after entering CLI Rescue:

• get wifi.status
• get wifi.ssid
• get wifi.powersaving
• set wifi.ssid <ssid>
• set wifi.pwd <password>
• set wifi.powersaving none|min|max

Active GitHub Workflows

• .github/workflows/build-companion-wifi-firmwares.yml
• .github/workflows/build-repeater-mqtt-firmwares.yml
• .github/workflows/pr-build-check.yml
• .github/workflows/push-build-check.yml
• .github/workflows/github-pages.yml

The current release workflows intentionally focus only on:

• companion-wifi
• repeater-mqtt

Release Tags

Current release tags are:

git tag companion-wifi-v1.14.1
git tag repeater-mqtt-eastmesh-v1.0.1

Companion WiFi uses the upstream MeshCore version in the tag.

Repeater MQTT uses:

• OFFICIAL_MESHCORE_VERSION from GitHub Actions variables as FIRMWARE_VERSION
• the EastMesh tag version as EASTMESH_VERSION

See RELEASE.md for the full release flow.
