Desktop App

The Meshtastic Desktop application shares its core codebase with Android via Kotlin Multiplatform. Most features work identically on Linux, macOS, and Windows.

Installation

Linux

• Download the .deb or .AppImage package from the releases page
• Or build from source using ./gradlew :desktopApp:run

macOS

• Download the .dmg package from releases
• Or build from source

Windows

• Download the .msi installer from releases
• Or build from source

Connecting Your Radio

USB Serial (Primary)

The most reliable connection method on Desktop:

1. Connect your Meshtastic radio via USB cable.
2. The app should detect the serial port automatically.
3. If not detected, select the correct serial port from the Connect menu.

TCP/IP

For network-connected radios:

1. Enter the radio's IP address and port (default: 4403).
2. Click Connect.

Bluetooth (BLE)

Bluetooth Low Energy is supported on Desktop via the Kable library:

1. Ensure your system has a Bluetooth adapter.
2. The app scans for nearby Meshtastic radios automatically.
3. Select your device from the Connect screen.

UI Differences

The Desktop app uses the same Compose Multiplatform UI with adaptations for larger screens and desktop interaction.

Keyboard Shortcuts

Shortcut	Action
⌘Q / Ctrl+Q	Quit the application
⌘, / Ctrl+,	Open Settings

Notification Preferences

The Desktop app provides in-app toggles for controlling which notifications are shown — messages, new nodes, and low battery alerts. Access these from Settings → Notifications within the app.

Built-in Documentation Browser

The Desktop app includes a built-in documentation browser for quick access to help content without leaving the application.

The browser supports full-text search across all documentation:

• Some Android-specific features (widgets, specific notification channels) are unavailable
• Performance may vary on low-spec hardware running Compose Desktop
• BLE bonding is not yet supported on desktop (pairing works without bonding)
