`:core:model` (Meshtastic Domain Models)

Overview

The :core:model module is a Kotlin Multiplatform (KMP) library containing the domain models and data classes used throughout the application and its API. These models are platform-agnostic and designed to be shared across Android, JVM, and future supported platforms.

Multiplatform Support

Models are plain commonMain Kotlin types — @Serializable (kotlinx.serialization) data classes and @JvmInline value classes — with no Android Parcelable dependency, so they are shared verbatim across Android, JVM, and iOS.

Key Models

DataPacket: Represents a mesh packet (text, telemetry, etc.).
Node: Contains detailed information about a node (position, SNR, battery, etc.).
NodeAddress / ContactKey: Type-safe node addressing (Broadcast/Local/ByNum/ById) and contact-key parsing, replacing stringly-typed "^all"/"!hex" handling.
DeviceHardware: Represents supported Meshtastic hardware devices and their capabilities.
Channel: Represents a mesh channel configuration.

Usage

This module is a core dependency of most feature modules.

// In commonMain
implementation(projects.core.model)

Structure

commonMain: Contains the majority of domain models and logic.
androidMain: Contains Android-specific utilities and implementations for expect declarations.
androidUnitTest: Contains unit tests that require Android-specific features (like Parcel testing via Robolectric).
