# Initial Concept A tool for using Android with open-source mesh radios. # Product Guide ## Overview Meshtastic-Android is a Kotlin Multiplatform (KMP) application designed to facilitate communication over off-grid, decentralized mesh networks using open-source hardware radios. ## Target Audience - Off-grid communication enthusiasts and hobbyists - Outdoor adventurers needing reliable communication without cellular networks - Emergency response and disaster relief teams ## Core Features - Direct communication with Meshtastic hardware (via BLE, USB, TCP, MQTT) - Decentralized text messaging across the mesh network - Unified cross-platform notifications for messages and node events - Adaptive node and contact management - Offline map rendering and device positioning - Device configuration and firmware updates - Unified cross-platform debugging and packet inspection ## Key Architecture Goals - Provide a robust, shared KMP core (`core:model`, `core:ble`, `core:repository`, `core:domain`, `core:data`, `core:network`, `core:service`) to support multiple platforms (Android, Desktop, iOS) - Ensure offline-first functionality and resilient data persistence (Room 3 KMP) - Decouple UI and navigation logic into shared feature modules (`core:ui`, `feature:*`) using Compose Multiplatform
