Meshtastic-Android

This is a tool for using Android (and Compose Desktop) with open-source mesh radios. For more information see our webpage: meshtastic.org. If you are looking for the device side code, see here.

If you have questions or feedback please Join our discussion forum or the Discord Group. We would love to hear from you!

Features

Highlights from the latest release:

• Full-text message search across your conversation history.
• Mesh network discovery to surface nodes and channels around you.
• Android Auto support for hands-free use while driving (google flavor).
• Air-quality telemetry — PM1.0, PM2.5, PM10, and CO₂ readings from supported sensors.
• Device hardware links via msh.to for quick access to hardware details.
• App Functions / system-AI integration so on-device assistants can trigger common workflows.

Get Meshtastic

The easiest and fastest way to get the latest releases is to use our GitHub releases. It is recommended to use these with Obtainium to get the latest updates automatically.

Alternatively, these other providers are also available, but may be slower to update.

The play store is the last to update of these options, but if you want to join the Play Store testing program go to this URL and opt-in to become a tester. If you encounter any problems or have questions, ask us on the discord, create an issue, or post in the forum and we'll help as we can.

Desktop

Meshtastic Desktop installers (macOS DMG, Windows MSI/EXE, Linux DEB/RPM/AppImage) are available from GitHub Releases. A Flatpak package is maintained at vidplace7/org.meshtastic.MeshtasticDesktop.

Documentation

Both sites are deployed to GitHub Pages automatically on every push to main.

Architecture

Modern Android Development (MAD)

The app follows modern Android development practices, built on top of a shared Kotlin Multiplatform (KMP) Core:

• KMP Modules: Business logic (core:domain), data sources (core:data, core:database, core:datastore), and communications (core:network, core:ble) are entirely platform-agnostic, targeting Android and Compose Desktop.
• UI: JetBrains Compose Multiplatform (Material 3) using Compose Multiplatform resources.
• State Management: Unidirectional Data Flow (UDF) with ViewModels, Coroutines, and Flow.
• Dependency Injection: Koin with Koin Annotations (K2 Compiler Plugin).
• Navigation: JetBrains Navigation 3 (Multiplatform routing with RESTful deep linking).
• Data Layer: Repository pattern with Room KMP (local DB), DataStore (prefs), and Protobuf (device comms). Protobuf models are consumed from the upstream org.meshtastic:protobufs Maven artifact, pinned in gradle/libs.versions.toml.

Bluetooth Low Energy (BLE)

The BLE stack uses a multiplatform interface-driven architecture. Platform-agnostic interfaces live in commonMain, utilizing the Kable multiplatform BLE library to handle device communication across all supported targets (Android, Desktop). This provides a robust, Coroutine-based architecture for reliable device communication while remaining fully KMP compatible. See core/ble/README.md for details.

Module Documentation

Each module has its own README with details on its responsibilities, API surface, and internal design.

Module	Description
core/domain	Business-logic use cases (radio config, sessions, exports)
core/repository	Data & infrastructure contracts (RadioTransport, NodeRepository, ServiceRepository)
core/takserver	Meshtastic ↔ TAK (ATAK/iTAK) bridge — CoT server & conversion
core/ble	Multiplatform BLE transport (Kable)
core/network	Internet comms: firmware metadata, map tiles, radio transports
core/data	Repository layer — orchestrates DB, network, and service data
core/database	Room KMP local persistence
core/datastore	DataStore preferences
core/service	Meshtastic Android service abstractions
core/navigation	Type-safe Navigation 3 route model
core/resources	Centralised CMP string & drawable resources
core/model	Shared domain models
core/ui	Shared UI components
core/common	Common utilities
core/di	Koin DI modules
core/testing	Shared test fakes & utilities

Translations

You can help translate the app into your native language using Crowdin.

Integration

The app includes a built-in Local TAK Server feature that can be enabled in settings. This runs a local TCP server on port 8089 to allow ATAK clients to connect directly and route their traffic over the mesh.

Building the Android App

[!WARNING] Debug and release builds can be installed concurrently. This is solely to enable smoother development, and you should avoid running both apps simultaneously. To ensure proper function, force quit the app not in use.

https://meshtastic.org/docs/development/android/

Note: when building the google flavor locally you will need to supply your own Google Maps Android SDK api key MAPS_API_KEY in local.properties in order to use Google Maps. e.g.

MAPS_API_KEY=your_google_maps_api_key_here
