+# Meshtastic Firmware - Copilot Instructions
+
+This document provides context and guidelines for AI assistants working with the Meshtastic firmware codebase.
+
+## Project Overview
+
+Meshtastic is an open-source LoRa mesh networking project for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware enables text messaging, location sharing, and telemetry over a decentralized mesh network.
+
+### Supported Hardware Platforms
+
+- **ESP32** (ESP32, ESP32-S3, ESP32-C3) - Most common platform
+- **nRF52** (nRF52840, nRF52833) - Low power Nordic chips
+- **RP2040/RP2350** - Raspberry Pi Pico variants
+- **STM32WL** - STM32 with integrated LoRa
+- **Linux/Portduino** - Native Linux builds (Raspberry Pi, etc.)
+
+### Supported Radio Chips
+
+- **SX1262/SX1268** - Sub-GHz LoRa (868/915 MHz regions)
+- **SX1280** - 2.4 GHz LoRa
+- **LR1110/LR1120/LR1121** - Wideband radios (sub-GHz and 2.4 GHz capable, but not simultaneously)
+- **RF95** - Legacy RFM95 modules
+- **LLCC68** - Low-cost LoRa
+
+### MQTT Integration
+
+MQTT provides a bridge between Meshtastic mesh networks and the internet, enabling nodes with network connectivity to share messages with remote meshes or external services.
+
+#### Key Components
+
+- **`src/mqtt/MQTT.cpp`** - Main MQTT client singleton, handles connection and message routing
+- **`src/mqtt/ServiceEnvelope.cpp`** - Protobuf wrapper for mesh packets sent over MQTT
+- **`moduleConfig.mqtt`** - MQTT module configuration
+
+#### MQTT Topic Structure
+
+Messages are published/subscribed using a hierarchical topic format:
+
+```
+{root}/{channel_id}/{gateway_id}
+```
+
+- `root` - Configurable prefix (default: `msh`)
+- `channel_id` - Channel name/identifier
+- `gateway_id` - Node ID of the publishing gateway
+
+#### Configuration Defaults (from `Default.h`)
+
+```cpp
+#define default_mqtt_address "mqtt.meshtastic.org"
+#define default_mqtt_username "meshdev"
+#define default_mqtt_password "large4cats"
+#define default_mqtt_root "msh"
+#define default_mqtt_encryption_enabled true
+#define default_mqtt_tls_enabled false
+```
+
+#### Key Concepts
+
+- **Uplink** - Mesh packets sent TO the MQTT broker (controlled by `uplink_enabled` per channel)
+- **Downlink** - MQTT messages received and injected INTO the mesh (controlled by `downlink_enabled` per channel)
+- **Encryption** - When `encryption_enabled` is true, only encrypted packets are sent; plaintext JSON is disabled
+- **ServiceEnvelope** - Protobuf wrapper containing packet + channel_id + gateway_id for routing
+- **JSON Support** - Optional JSON encoding for integration with external systems (disabled on nRF52 by default)
+
+#### PKI Messages
+
+PKI (Public Key Infrastructure) messages have special handling:
+
+- Accepted on a special "PKI" channel
+- Allow encrypted DMs between nodes that discovered each other on downlink-enabled channels

+
+## Coding Conventions
+
+### General Style
+
+- Follow existing code style - run `trunk fmt` before commits
+- Prefer `LOG_DEBUG`, `LOG_INFO`, `LOG_WARN`, `LOG_ERROR` for logging
+- Use `assert()` for invariants that should never fail
+
+### Naming Conventions
+
+- Classes: `PascalCase` (e.g., `PositionModule`, `NodeDB`)
+- Functions/Methods: `camelCase` (e.g., `sendOurPosition`, `getNodeNum`)
+- Constants/Defines: `UPPER_SNAKE_CASE` (e.g., `MAX_INTERVAL`, `ONE_DAY`)
+- Member variables: `camelCase` (e.g., `lastGpsSend`, `nodeDB`)
+- Config defines: `USERPREFS_*` for user-configurable options
+
+### Key Patterns
+
+#### Module System
+
+Modules inherit from `MeshModule` or `ProtobufModule<T>` and implement:
+
+- `handleReceivedProtobuf()` - Process incoming packets
+- `allocReply()` - Generate response packets
+- `runOnce()` - Periodic task execution (returns next run interval in ms)
+
+```cpp
+class MyModule : public ProtobufModule<meshtastic_MyMessage>
+{
+  protected:
+    virtual bool handleReceivedProtobuf(const meshtastic_MeshPacket &mp, meshtastic_MyMessage *msg) override;
+    virtual int32_t runOnce() override;
+};
+```
+
+#### Configuration Access
+
+- `config.*` - Device configuration (LoRa, position, power, etc.)
+- `moduleConfig.*` - Module-specific configuration
+- `channels.*` - Channel configuration and management
+
+#### Default Values
+
+Use the `Default` class helpers in `src/mesh/Default.h`:
+
+- `Default::getConfiguredOrDefaultMs(configured, default)` - Returns ms, using default if configured is 0
+- `Default::getConfiguredOrMinimumValue(configured, min)` - Enforces minimum values
+- `Default::getConfiguredOrDefaultMsScaled(configured, default, numNodes)` - Scales based on network size
+
+#### Thread Safety
+
+- Use `concurrency::Lock` for mutex protection
+- Radio SPI access uses `SPILock`
+- Prefer `OSThread` for background tasks
+
+### Hardware Variants
+
+Each hardware variant has:
+
+- `variant.h` - Pin definitions and hardware capabilities
+- `platformio.ini` - Build configuration
+- Optional: `pins_arduino.h`, `rfswitch.h`
+
+Key defines in variant.h:
+
+```cpp
+#define USE_SX1262          // Radio chip selection
+#define HAS_GPS 1           // Hardware capabilities
+#define LORA_CS 36          // Pin assignments
+#define SX126X_DIO1 14      // Radio-specific pins
+```
+
+### Protobuf Messages
+
+- Defined in `protobufs/meshtastic/*.proto`
+- Generated code in `src/mesh/generated/`
+- Regenerate with `bin/regen-protos.sh`
+- Message types prefixed with `meshtastic_`
+
+### Conditional Compilation
+
+```cpp
+#if !MESHTASTIC_EXCLUDE_GPS        // Feature exclusion
+#ifdef ARCH_ESP32                   // Architecture-specific
+#if defined(USE_SX1262)            // Radio-specific
+#ifdef HAS_SCREEN                   // Hardware capability
+#if USERPREFS_EVENT_MODE           // User preferences
+```
+
+## Build System
+
+Uses **PlatformIO** with custom scripts:
+
+- `bin/platformio-pre.py` - Pre-build script
+- `bin/platformio-custom.py` - Custom build logic
+
+Build commands:
+
+```bash
+pio run -e tbeam              # Build specific target
+pio run -e tbeam -t upload    # Build and upload
+pio run -e native             # Build native/Linux version
+```
+
+## Common Tasks
+
+### Adding a New Module
+
+1. Create `src/modules/MyModule.cpp` and `.h`
+2. Inherit from appropriate base class
+3. Register in `src/modules/Modules.cpp`
+4. Add protobuf messages if needed in `protobufs/`
+
+### Adding a New Hardware Variant
+
+1. Create directory under `variants/<arch>/<name>/`
+2. Add `variant.h` with pin definitions
+3. Add `platformio.ini` with build config
+4. Reference common configs with `extends`
+
+### Modifying Configuration Defaults
+
+- Check `src/mesh/Default.h` for default value defines
+- Check `src/mesh/NodeDB.cpp` for initialization logic
+- Consider `isDefaultChannel()` checks for public channel restrictions
+
+## Important Considerations
+
+### Traffic Management
+
+The mesh network has limited bandwidth. When modifying broadcast intervals:
+
+- Respect minimum intervals on default/public channels
+- Use `Default::getConfiguredOrMinimumValue()` to enforce minimums
+- Consider `numOnlineNodes` scaling for congestion control
+
+### Power Management
+
+Many devices are battery-powered:
+
+- Use `IF_ROUTER(routerVal, normalVal)` for role-based defaults
+- Check `config.power.is_power_saving` for power-saving modes
+- Implement proper `sleep()` methods in radio interfaces
+
+### Channel Security
+
+- `channels.isDefaultChannel(index)` - Check if using default/public settings
+- Default channels get stricter rate limits to prevent abuse
+- Private channels may have relaxed limits
+
+## GitHub Actions CI/CD
+
+The project uses GitHub Actions extensively for CI/CD. Key workflows are in `.github/workflows/`:
+
+### Core CI Workflows
+
+- **`main_matrix.yml`** - Main CI pipeline, runs on push to `master`/`develop` and PRs
+  - Uses `bin/generate_ci_matrix.py` to dynamically generate build targets
+  - Builds all supported hardware variants
+  - PRs build a subset (`--level pr`) for faster feedback
+
+- **`trunk_check.yml`** - Code quality checks on PRs
+  - Runs Trunk.io for linting and formatting
+  - Must pass before merge
+
+- **`tests.yml`** - End-to-end and hardware tests
+  - Runs daily on schedule
+  - Includes native tests and hardware-in-the-loop testing
+
+- **`test_native.yml`** - Native platform unit tests
+  - Runs `pio test -e native`
+
+### Release Workflows
+
+- **`release_channels.yml`** - Triggered on GitHub release publish
+  - Builds Docker images
+  - Packages for PPA (Ubuntu), OBS (openSUSE), and COPR (Fedora)
+  - Handles Alpha/Beta/Stable release channels
+
+- **`nightly.yml`** - Nightly builds from develop branch
+
+- **`docker_build.yml`** / **`docker_manifest.yml`** - Docker image builds
+
+### Build Matrix Generation
+
+The CI uses `bin/generate_ci_matrix.py` to dynamically select which targets to build:
+
+```bash
+# Generate full build matrix
+./bin/generate_ci_matrix.py all
+
+# Generate PR-level matrix (subset for faster builds)
+./bin/generate_ci_matrix.py all --level pr
+```
+
+Variants can specify their support level in `platformio.ini`:
+
+- `custom_meshtastic_support_level = 1` - Actively supported, built on every PR
+- `custom_meshtastic_support_level = 2` - Supported, built on merge to main branches
+- `board_level = extra` - Extra builds, only on full releases
+
+### Running Workflows Locally
+
+Most workflows can be triggered manually via `workflow_dispatch` for testing.
+
+## Testing
+
+- Unit tests in `test/` directory
+- Run with `pio test -e native`
+- Use `bin/test-simulator.sh` for simulation testing
+
