:core:service

Overview

Targets: Android · JVM (Desktop) · iOS

The :core:service module contains the abstractions and client-side logic for interacting with the main Meshtastic Android Service.

Key Components

1. MeshService

Android foreground service entry point that hosts the orchestrator lifecycle.

2. ServiceRepository

A high-level repository that wraps the service connection and exposes reactive Flows for connection status and data arrival.

3. ConnectionState

Represents the current state of the radio connection (Connected, Disconnected, DeviceSleep, etc.).

4. RadioControllerImpl

The in-process RadioController composition root (Desktop, iOS, and single-process Android). It assembles four focused sub-controllers — AdminControllerImpl, MessagingControllerImpl, NodeControllerImpl, QueryControllerImpl — via Kotlin interface delegation, and owns the cross-cutting concerns (connection state, packet-id, location, device-address switching). Commands are direct suspend calls to CommandSender; admin sends are fire-and-forget (the device is the source of truth). Config writes use the editSettings { } transaction.
