LoRaWAN Network Server
Overview
The LoRaWAN module transforms Ignition into a complete LoRaWAN network server. It accepts connections from LoRaWAN gateways using the industry-standard Semtech Packet Forwarder protocol, manages device registrations, handles join procedures, and exposes all device and gateway data through real-time Ignition tags.
Features
- Complete Network Server - Full LoRaWAN network server implementation
- Multi-Gateway Support - Connect multiple gateways with automatic uplink deduplication
- OTAA & ABP Activation - Support for both Over-the-Air and pre-provisioned device activation
- Class A & C Devices - Support for battery-optimized and always-listening devices
- Real-Time Tags - All device and gateway data exposed via
[LoRaWAN]tag provider - Payload Decoders - JavaScript-based payload decoding with dynamic tag creation
- Adaptive Data Rate - Automatic optimization of device transmission parameters
- Downlink Queue - Queue and manage downlink messages to devices
- MAC Command Support - LinkCheck, LinkADR, DevStatus, RXParamSetup, and more
- Web Configuration - Full web UI for settings, gateways, and device management
- REST API - Complete API for device registration and downlink management

Architecture
The module implements a complete LoRaWAN network server inside the Ignition gateway. When a device transmits data:
- LoRaWAN gateways receive the RF transmission and forward it via UDP (Semtech Packet Forwarder protocol) to the module's built-in UDP server (port 1700)
- The network server performs uplink deduplication across multiple gateways
- The device registry validates the frame (OTAA join or data frame) and manages session keys
- Payload decoders (JavaScript) transform raw bytes into meaningful values
- All data is exposed in real time through the
[LoRaWAN]tag provider (Devices/, Gateways/, _Meta/*) - For downlinks, messages are queued and transmitted during the device's next RX window
Data Flow
- Uplink: Device transmits → Gateway receives → UDP to Ignition → Tags updated
- Downlink: Queue via API/tags → Wait for RX window → Gateway transmits → Device receives
- Join (OTAA): Device sends JoinRequest → Server validates → JoinAccept sent → Session established
