MQTT

Over ten years ago, the Eclipse Foundation launched the Eclipse IoT working group . MQTT was one of the pillars of that launch. The first three projects were Eclipse Paho , a collection of MQTT clients, Eclipse Mosquitto , an MQTT broker, and Eclipse Kura , a Java/OSGi solution for...

Boasting an audience of over 2,500 IoT enthusiasts, the Virtual IoT Meetup Group brings together a world-wide network of developers dedicated to discovering and creating new technologies that will make it easier to create IoT applications. In 2020, the group gathered four times through Eclipse Foundation organized events to discuss...

For many years, the Eclipse Foundation has offered an MQTT sandbox to the IoT developer community. That sandbox was maintained by Foundation staff and was running on Foundation infrastructure. The goal was to encourage and facilitate the evaluation of Eclipse Paho and Eclipse Mosquitto , and to foster interoperability among...

A couple of days ago, Google announced that they were essentially rebranding Brillo to Android Things (I do love that name, by the way!), and finally opening it for a Developer Preview. There are a few things I already like very much in Android Things: It is already supported on...

I was just asked how one can deploy a similar setup as the iot.eclipse.org MQTT sandbox , where MQTT over WebSockets is available on port 80, just like the rest of the website. There are actually two ways of achieving this. Mosquitto as the main frontend It’s a little-known fact...

I’ve recently been playing around with Snappy Ubuntu Core , and I thought it would be a nice exercise to try and package Mosquitto as a so-called “Snap”. This blog post will give you a quick introduction to Snappy, and what it means to have a technology like Mosquitto available...

What I really like with MQTT and CoAP is that they both are very simple protocols. When dealing with MQTT, the client itself has almost no state to maintain (at least when you stick to QoS 0 communications) and granted that you have an MQTT packet serializer/unserializer, it’s very simple...

In just about a week is EclipseCon France , and here’s one more reason why it’s going to be awesome! This year you will all be actors of a real-world Internet of Things setup, that leverages several Eclipse IoT technologies. We’ve been wanting to do this for a couple years...

The Rapiro is a nice open-hardware robot, controlled by an Arduino and a Raspberry Pi. Earlier this week, I decided that he’d be nice if I could run Eclipse Orion directly on the robot, allowing me to write an app that would bridge the Rapiro to the Internet (there’s a...

1. Wunderbar – looks like an interesting kit of hardware and software for IoT applications. They seem to be using MQTT for the message protocol. 2. Comparing bandwidth consumption between MQTT, AMQP and TCP – perfect illustration on why an IoT protocol like MQTT is needed. 3. New MQTT-SN (Sensor...
