Large-scale LoRaWAN deployments become easier through QR codes and relays

LoRaWAN devices typically require users to enter parameters such as the DevEUI, JoinEUI (formerly AppEUI), AppKey, and potentially the DevAddr plus the session keys, depending on the activation mode (ABP vs OTAA). This is manageable for a handful of devices, but becomes time-consuming, error-prone, and costly at scale. To make the onboarding process easier and scale LoRaWAN networks more effectively, the LoRa Alliance has now introduced three new documents: the TS014 and TS018 specifications and the TR016 technical recommendations. They should all help users get a device onto a network quickly, securely, and with minimal manual work, such as scanning a QR code. Here are the links and summaries for all three documents: TS014-1.0.0 – LoRaWAN End-Device Capabilities API Specification – TS014 eliminates manual data entry and proprietary workarounds by enabling LoRaWAN networks to automatically pull device profiles. It specifically describes a standard interface which enables the hNS (Home Network […]

RAKwireless WisMesh Pi HAT RAK6421 turns your Raspberry Pi 4/5 into a modular Meshtastic gateway

RAKwireless WisMesh Pi HAT RAK6421 meshtasticd HAT for Raspberry Pi

RAKwireless WisMesh Pi HAT RAK6421 is a modular Meshtastic gateway expansion board for Raspberry Pi 4/5 that adds support for the company’s WisBlock ecosystem. Designed for users running meshtasticd (the Linux-native Meshtastic service), it enables scalable, always-on Meshtastic base stations, MQTT gateways, and backbone relay nodes. Unlike other LoRa solutions based on Raspberry Pi, the RAK6421 takes a modular approach. Instead of a built-in radio, it offers two WisBlock IO slots and four sensor slots, allowing users to easily plug in or swap modules. This means you can choose between standard LoRa modules like the RAK13300 or higher-power 1W versions like the RAK13302, without dealing with messy USB adapters or breadboard wiring. RAK6421 WisMesh Pi HAT RAK6421 specifications: Compatibility Raspberry Pi 4, Raspberry Pi 5, and Raspberry Pi Zero 2W SBCs Potentially other SBC with standard 40-pin Raspberry Pi GPIO header (HAT+ compliant) Expansion 2x WisBlock IO slots for LoRa radio […]
