HMS eWON Flexy IIoT gateway

HMS Industrial Networks has announced that its IIoT gateway range, eWON Flexy, now supports Message Queue Telemetry Transport (MQTT) protocol, a simple and lightweight messaging protocol aimed at minimising network traffic and device resource requirements.

Initially created in 1999 to help oil and gas distribution firms control their pipelines effectively, MQTT has recently seen increased popularity because of the exponential growth of the IoT and the need to facilitate communication between low-powered smart devices.

MQTT is essentially a publish/subscribe protocol aimed specifically at low-powered embedded devices. One of the upsides of using the MQTT protocol with eWON Flexy includes the ability to resume operations from any breakpoint without data loss. In addition, during network interruptions, data can be buffered until network communication is resumed and a client device reads the data. This not only prevents data loss but also allows users to manage the information flow to network nodes.

Designed to facilitate the transmission of large volumes of data to numerous servers and client devices constrained by low bandwidth, high latency or unreliable networks, MQTT is suitable for dynamic communication environments. As the name indicates, the main purpose of the MQTT protocol is telemetry.
