# 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 is a community-driven mesh network across Eastern Australia. This repository provides tailored builds of MeshCore, including WiFi companion firmware with additional CLI tools and Observer firmware that integrates with our CoreScope telemetry platform.

CoreScope (<https://core.eastmesh.au>) offers visibility into the network, including repeater status, observers, and mapping data.

**Observer builds feed EastMesh Core telemetry and are intended for Eastern Australia repeaters only**; running them elsewhere can skew shared network data.

## What This Repo Adds

- `*_repeater_observer` firmware targets with:
  - native WiFi
  - MQTT over WSS with JWT auth
  - optional local HTTPS config panel on supported ESP32 targets
- `*_repeater_observer_espnow` firmware targets that add a local ESP-NOW mesh bridge
- `*_repeater_bridge_espnow` firmware targets for a plain upstream-style repeater ESP-NOW bridge, without MQTT uplink or the EastMesh web panel
- `*_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>

## Key EastMesh Features

### MQTT Repeater Additions

- curated broker support for:
  - `eastmesh-au`
  - `meshmapper`
  - `waev`
  - `letsmesh-eu` (retired)
  - `letsmesh-us` (retired)
- 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

### MQTT Mesh Bridge (Observer)

The `observer-eastmesh-bridge-mqtt` release track (`*_repeater_observer_mqtt_bridge`) bridges **raw mesh packets** between repeaters through a **peer MQTT broker you run** (for example Mosquitto on a LAN PC). This is **not** the same as MQTT uplink to EastMesh/MeshMapper:

| | MQTT uplink (observer) | MQTT mesh bridge |
| --- | --- | --- |
| Purpose | Publish JSON telemetry to curated brokers | Forward encrypted mesh packets between radios |
| Brokers | `eastmesh-au`, `meshmapper`, custom WSS | Your peer broker (`host:port`, TCP) |
| Topic | `meshcore/<iata>/...` (per IATA) | `meshcore/bridge/packets` (fixed) |
| Default on bridge builds | Off by default (enable in web panel / CLI) | On when `bridge.enabled` is on |

**First supported target:** `Xiao_S3_WIO_repeater_observer_mqtt_bridge`

**Related track:** `observer-eastmesh-bridge-espnow` (`*_repeater_observer_espnow`) uses ESP-NOW instead of MQTT for local bridging.

Build example:

```bash
uv run pio run -e Xiao_S3_WIO_repeater_observer_mqtt_bridge
```

Flash (update):

```bash
uv run pio run -e Xiao_S3_WIO_repeater_observer_mqtt_bridge -t upload --upload-port COM10
```

After a **full flash erase**, flash the merged image at `0x0` instead of only `firmware.bin`:

```bash
uv run pio run -e Xiao_S3_WIO_repeater_observer_mqtt_bridge -t mergebin
uv run pio pkg exec -p tool-esptoolpy -- esptool.py --chip esp32s3 --port COM10 write_flash 0x0 .pio/build/Xiao_S3_WIO_repeater_observer_mqtt_bridge/firmware-merged.bin
```

#### Peer Mosquitto broker (LAN)

Each bridge node connects to the **same** peer broker with the **same** credentials and `bridge.secret`.

1. Install [Mosquitto](https://mosquitto.org/download/) on a machine reachable from both repeaters (for example `192.168.1.145`).
2. Edit `mosquitto.conf` (Windows service install: `C:\Program Files\Mosquitto\mosquitto.conf`) and add:

```conf
listener 1883 0.0.0.0
allow_anonymous false
password_file C:\Program Files\Mosquitto\passwd
```

For lab/testing only, `allow_anonymous true` works without a password file.

3. Create a user (admin CMD):

```cmd
cd "C:\Program Files\Mosquitto"
mosquitto_passwd -c passwd bridgeuser
```

4. Restart the **service** (do not run a second `mosquitto -v` while the service owns port 1883):

```powershell
Restart-Service mosquitto
```

5. Confirm LAN listen and open the firewall:

```cmd
netstat -ano | findstr ":1883"
```

Expect `0.0.0.0:1883`, not only `127.0.0.1:1883`.

6. Test from another machine:

```cmd
mosquitto_pub -h 192.168.1.145 -p 1883 -u bridgeuser -P your-password -t test -m hello
mosquitto_sub -h 192.168.1.145 -p 1883 -u bridgeuser -P your-password -t meshcore/bridge/packets -v
```

Binary garbage on `meshcore/bridge/packets` is normal — payloads are XOR-encrypted mesh frames, not text.

#### Repeater configuration

Configure **both** bridge nodes identically for broker access; use the same `bridge.secret` on every node in the bridge group.

Serial or web panel CLI:

```text
set wifi.ssid YourNetwork
set wifi.pwd YourWiFiPassword
set bridge.peer.host 192.168.1.145
set bridge.peer.port 1883
set bridge.peer.username bridgeuser
set bridge.peer.password your-password
set bridge.secret your-shared-bridge-secret
```

Web panel: **MQTT Settings** → **Mesh bridge peer MQTT** (`host:port`, username, password). The section appears when `get bridge.type` returns `mqtt`.

Useful checks:

```text
get bridge.type
get bridge.peer.host
get bridge.enabled
```

Default admin password on dev builds is usually `password` unless you changed it.

Packets use magic `0xC03E`, a Fletcher checksum, XOR encryption with `bridge.secret`, then publish/subscribe on `meshcore/bridge/packets`. Duplicate detection limits loops when both nodes see the same traffic.

More detail:

- [Custom CLI — MQTT bridge settings](./eastmesh-docs/custom-cli.md)
- [Web panel — MQTT settings and bridge peer fields](./eastmesh-docs/web-panel.md)
- [Releases — track comparison](./eastmesh-docs/releases.md)

### Local Web Panel

On supported `*_repeater_observer` 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 observer deployments, disable the panel again when finished if you want maximum MQTT heap headroom.

### 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/eastmesh-build-companion-wifi-firmwares.yml`
- `.github/workflows/eastmesh-build-observer-firmwares.yml`
- `.github/workflows/eastmesh-build-repeater-bridge-espnow-firmwares.yml`

- `.github/workflows/eastmesh-pr-build-check.yml`
- `.github/workflows/eastmesh-push-build-check.yml`
- `.github/workflows/eastmesh-github-pages.yml`

The upstream MeshCore workflows are retained under their original filenames to reduce merge conflicts. They are not part of the EastMesh release flow and should stay disabled in GitHub Actions for this repository.

The current release workflows intentionally focus only on:

- `companion-wifi`
- `repeater-bridge-espnow`
- `observer-eastmesh`
- `observer-eastmesh-bridge-espnow`
- `observer-eastmesh-bridge-mqtt`

## Release Tags

Current release tags are:

```bash
git tag companion-wifi-v1.14.1
git tag repeater-bridge-espnow-v1.15.0
git tag observer-eastmesh-v2026.5.1
git tag observer-eastmesh-bridge-espnow-v2026.5.1
git tag observer-eastmesh-bridge-mqtt-v2026.7.0
```

Companion WiFi uses the upstream MeshCore version in the tag.

Observer uses:

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

See [RELEASE.md](./RELEASE.md) for the full release flow.
