1. Why Legacy Devices Are Difficult to Integrate into IoT Systems Industrial sites still rely heavily on RS485 meters, pulse counters and proprietary-protocol instruments. These devices usually suffer from: LoRaWAN provides long-range, low-power and cable-free connectivity, making it ideal for upgrading legacy devices. A practical solution, however, requires edge logic and a lightweight cloud platform. […]

As LoRaWAN deployments expand across smart cities, industrial IoT, smart buildings, utilities, and agriculture, enterprise users increasingly require secure, stable, and manageable network architectures. The LoRaWAN gateway, typically deployed outdoors or at industrial sites, is the core connectivity node of the entire network. Its long-term remote accessibility directly affects the system’s reliability and operational efficiency.

EdgeBus is a low power event driven virtual machine framework designed by Manthink for IoT edge devices operating on resource constrained MCUs. It provides a unified mechanism for data acquisition, protocol parsing, data encapsulation, uplink transmission and firmware upgrade over LPWAN networks such as LoRaWAN. EdgeBus solves essential system challenges including version management, remote FUOTA,

In a LoRaWAN architecture, the gateway forms the core link between end devices and the Network Server (NS). Its capability to receive, decode, and forward uplink frames is primarily determined by its RF front-end and the baseband processing architecture. Modern LoRaWAN gateways commonly adopt the Semtech SX1302 chipset, which significantly enhances concurrent reception and multi-channel

Over the air firmware update is a core requirement for large scale IoT deployments especially when LoRaWAN devices are distributed in remote and inaccessible environments Since LoRaWAN provides low data rate strict payload limitation and downlink constraints FUOTA becomes a technical challenge This article explains the engineering difficulties behind LoRaWAN FUOTA and presents Manthink’s mature

In large-scale IoT deployments, many devices operate in locations where physical maintenance is nearly impossible. Firmware Update Over the Air (FUOTA) becomes indispensable for long-term device stability, especially for LoRaWAN devices operating on low bandwidth and limited payload size. This article explains the technical principles behind FUOTA, analyzes LoRaWAN-specific challenges, and introduces Manthink’s engineering-grade upgrade

1. Introduction LoRaWAN is widely adopted as an LPWAN technology due to long-range communication, low power consumption and cost-effective deployment. The Network Server (NS) is a critical component within the LoRaWAN architecture: it handles device activation, message routing, encryption/decryption, network management and operator-level controls. Selecting the appropriate NS has direct implications for reliability, scalability, operational
