NodeRadioTransport runs a meshtastic-node-kmp MeshNode inside the app and speaks the firmware phone API to it over PhoneApiSession, so every screen works on top of the phone's own node with no radio in the path: BLE advertisements and mesh-peer GATT to other phones and BLE-mesh radios, and LoRa through a CH341 stick on the USB-C port. Config writes land in the node's AdminService and persist; a lora write rebuilds the bearer the way a radio reboots for one. TX power is capped at 10 dBm for a bus-powered stick. Offered as "This device as a mesh node" behind the Demo Mode gate, address prefix 'p'. BLUETOOTH_ADVERTISE joins the manifest and the runtime set, since the node is a peripheral and an advertiser. Demo branch for VCF Midwest: depends on node-kmp from ~/.m2 (-PuseMavenLocal=1, 0.1.0-pb2.8.0.35-g3b3df2a-SNAPSHOT, built from e808296 against this app's protobufs pin), so it is not mergeable as-is and skips the spec lifecycle on purpose. No foreground service yet; Wi-Fi Aware and UDP not wired in.
:androidApp
Overview
The :androidApp module is the entry point for the Meshtastic Android application. It orchestrates the various feature modules, manages global state, and provides the main UI shell.
Key Components
1. MainActivity & Main.kt
The single Activity of the application. It hosts the shared MeshtasticNavDisplay navigation shell and manages the root UI structure (Navigation Bar, Rail, etc.).
2. MeshService
The core background service that manages long-running communication with the mesh radio. While it is declared in the :androidApp manifest for system visibility, its implementation resides in the :core:service module. It runs as a Foreground Service to ensure reliable communication even when the app is in the background.
3. Koin Application
MeshUtilApplication is the Koin entry point, providing the global dependency injection container.
Architecture
The module primarily serves as a "glue" layer, connecting:
core:*modules for shared logic.feature:*modules for specific user-facing screens.
