Interoperability testing at EclipseCon 2014

January 22nd, 2014 - No Comments

The Eclipse Paho project is rapidly becoming a source of some great MQTT clients – currently it contains implementations in C, Java, Javascript, Python (contributed from the mosquitto project), Lua, C++, embedded/minimal C, Go… and an Objective-C client is about to be added. The very popular mosquitto broker recently moved under the Eclipse umbrella too – the Eclipse Mosquitto project contains both mosquitto, and a fully open-sourced Really Small Message Broker from IBM, which also happens to support MQTT-SN.

EclipseCon 2014, coming up in March, has a strong focus on the Internet of Things.

As part of EclipseCon, the Eclipse Foundation is delighted to host an interoperability testing day for MQTT developers and vendors. The goal is to have representation from a wide range of MQTT brokers, clients, and MQTT-enabled devices. If you work with MQTT, take a look at the Eventbrite page to sign up for the interoperability testing, and check the Eclipse Paho wiki page for more infomation. If you are building APIs or devices on top of MQTT, this is a great way of interacting with the community, broadening awareness of your project or product, and making sure that things work smoothly for you users and customers!

Feel free to contact the Eclipse Paho team via their mailing list, if you have any questions.

OASIS announce 30-day Public Review for MQTT Version 3.1.1

January 10th, 2014 - No Comments

A significant milestone has been reached in efforts to standardise MQTT. The OASIS MQTT Technical Committee have approved a Committee Specification Draft which is now open for a 30-day public review.

The public review starts 13 January 2014 at 00:00 GMT and ends 11 February 2014 at 23:59 GMT.

This is an open invitation to comment. OASIS solicits feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of its technical work.

More details are available in the announcement.

MQTT for Sensor Networks – MQTT-SN

December 2nd, 2013 - 3 Comments

The nomenclature of “MQTT-S” (sensors? security? sausages?) has been confusing to some people, so recently there was a discussion about renaming the protocol to MQTT-SN.

The new name would be MQTT-SN, standing for exactly the same long name, MQTT for Sensor Networks.  Some people had assumed that the S in MQTT-S stood for secure, so we hope this change will avoid that confusion.

As part of this change, the copy of the specification now available from the mqtt.org Documentation page now reflects that name change, and links to all previous versions of the specification have been permanently redirected. This is still version 1.2 of the specification, updated to reflect the changed name. MQTT for Sensor Networks is aimed at embedded devices on non-TCP/IP networks, whereas MQTT itself explicitly expects a TCP/IP stack.

So, how can you get started with MQTT-SN? Here’s the exciting part – Really Small Message Broker and Mosquitto are coming together in a new Eclipse project, called Eclipse Mosquitto (here’s the project proposal). The RSMB source code is now available at Eclipse, and it has built-in MQTT-SN support… Ian Craggs shares a very quick getting started guide on his blog. It turns out that Nicholas Humfrey’s tools for MQTT-SN work well with RSMB as well!

MQTT proposed as an OASIS standard

February 5th, 2013 - 1 Comment

Per the announcement on the OASIS website:

The purpose of the Message Queuing Telemetry Transport (MQTT) Technical Committee is to define an open publish/subscribe protocol for telemetry messaging designed to be open, simple, lightweight, and suited for use in constrained networks and multi-platform environments. The TC will accomplish this purpose through the refinement of an input specification.

The intention is to use the current MQTT v3.1 specification as the input to the Technical Committee and incorporate clarifications that the community has been curating on the wiki.

The deadline for joining the process is March 18th 2013 – please take part if this is of interest to you and/or your organisation.

MQTT inventors speak at TEDx

November 5th, 2012 - No Comments

Worth sharing a couple of videos of the two main inventors of the MQTT protocol – Andy Stanford-Clark and Arlen Nipper – speaking at two different TEDx events in the past few months.

First up a few months ago was Andy, with his appearance at TEDx Warwick in the UK – “Innovation begins at Home”

[youtube https://www.youtube.com/watch?v=s9nrm8q5eGg]

More recently, Arlen went on stage at TEDx New Bedford in the US – “The Internet of Things is Just Getting Started”

[youtube https://www.youtube.com/watch?v=qA1Nt_0XomY]

Both videos are worth watching to get some insight into what these guys are working on, thinking about, and (in part) how MQTT came about!

What do you think? Tweet us @mqttorg and let us know your views!

Free webinar – learn more about MQTT

September 21st, 2012 - No Comments

Just a note to point out that the Eclipse M2M Industry Working Group is currently running a series of free webinars about machine-to-machine / Internet of Things development. The next one in the series, on Thursday September 27th, focuses specifically on MQTT with two of the lead developers from IBM.

Here’s the abstract:

MQTT is a connectivity protocol designed for M2M. It is an extremely lightweight publish/subscribe messaging transport that is ideal for connecting small devices connected on networks with minimal bandwidth. The Eclipse Paho project is the reference implementation for the MQTT protocol. This webinar will introduce developers to MQTT and then show how you can develop your very first MQTT based application using Paho and the Eclipse IDE.

So, just to recap – free education, provided by some of the leading developers in the MQTT community. Sign up and get it in your calendar!

(oh, and the other talks in the series are also worth joining – they have already covered the goals of the M2M efforts at Eclipse, and the anatomy of an M2M application, with more technical talks to come!)

Mosquitoes! Rabbits! Facebook! Portals! (news round-up)

September 13th, 2012 - No Comments

Lots of community news to talk about this time around… I was about to type “let’s start with the big stories”, but then realised that they are all big!

Mosquitto 1.x

After a couple of years in development, the popular fully Open Source MQTT broker, mosquitto by Roger Light, hit version 1.0. Check out the long list of enhancements in the announcement post, including comprehensive SSL/TLS support, better password management, a rewritten pure Python client, a Javascript/websockets client, and “masses of bug fixes”. A couple of additional point releases followed quickly after the major release, so it’s looking very polished. Roger has given a lot of time to the MQTT community, so if you use mosquitto please let him know – and why not donate, as a thank you for all his hard work? There’s a link to do so on the mosquitto homepage.

(even) More brokers

The Software page has been updated to list a number of new server/broker implementations including Apache ActiveMQ and Apollo, and the just-announced RabbitMQ adapter for MQTT. The latter is particularly exciting, as it offers interoperability between the AMQP and MQTT protocols.

As there are a number of publically-accessible brokers now, we’ve made a list so that you can get testing with MQTT more quickly. We’ve also started to look at protocol compliance / completeness on a new page on the wiki – please help to update this page (and all of the wiki!).

update: moments after posting this, moquette-mqtt also released an early version of a new Java broker implementation. Worth a look.

More software

Beyond the brokers, we now have more clients (new Javascript, Objective-C, Python APIs) listed; and some client tools for testing, such as the excellent mqtt.io.

Facebook apps using (more) MQTT

A year after Facebook first went public about their use of MQTT within Facebook Messenger, the new native iOS Facebook app also credits the libmosquitto library and their blog post mentions that they are using MQTT extensively for notifications and updates. This has led to analysts like James Governor and news outlets like ReadWriteWeb writing pieces on the change. Of course, the endpoints themselves are not public – but that’s not the point.  It’s a good use of the protocol (it is efficient on battery, CPU and network in mobile scenarios), and it’s a great validation for the use case.

Eclipse Paho and Eclipse M2M Portal

The Eclipse Paho project is the primary home of the reference MQTT clients that started at IBM. Paho is a core project inside the Eclipse M2M Industry Working Group. The Java and C clients are being cleaned up, there is a nice Eclipse view for testing, and a Lua client has been contributed, so progress is being made. As of today, there’s also a brand new portal where developers can go to find their way around the projects, frameworks, and resources provided by the M2M initiative at Eclipse. You’ll find MQTT featured on the Protocols page, and a Sandbox page which discusses how to connect to the test broker provided by Eclipse.

MQTT, the book

IBM published a Redbook, Building Smarter Planet Solutions with MQTT and IBM WebSphere MQ Telemetry. This should be a great read both for those wanting to learn the basics of MQTT, and also those looking to integrate with WebSphere MQ. Redbooks are very comprehensive and this one weighs in at 268 pages, available for free in PDF and Ebook formats. Take a look.

 

Places to talk about MQTT

July 4th, 2012 - No Comments

There are a number of mailing lists and discussion groups and spaces for MQTT now, so I thought it might be useful to quickly summarise the main ones – and clarify what they are for.

Users of all of the lists are generally very friendly and can help you to navigate between them, but I just thought it would be useful to explain the “main purpose” of each group. Discussions are not limited to mailing lists and happen on Twitter, in IRC, and across the web. We try to follow as many of them as possible! There’s an additional list on the Community page.

For more about MQTT and the relationship to Eclipse, check our wiki page MQTT at Eclipse. For more on mosquitto, check out that project’s excellent website!

MQTT Service Hook added to Github

May 3rd, 2012 - 5 Comments

Thanks to a pull-request from friend of MQTT @zer0c00l, GitHub now has the ability to publish an MQTT message whenever a repository has a change pushed to it.

To get your repository publishing, find your way to its admin page.

From there, under the Service Hooks tab, select the MqttPub hook in the list to bring up the configuration options.

The options speak for themselves, but there are some handy notes provided to help you figure it out. Be sure to check the ‘active’ box before hitting Update Settings.

With that done, you should start to get messages published whenever something is committed to the repository. The message itself is a json blob that contains all of the information about the commit that you could possible want.

You can read more about the contents of the blob on GitHub’s Post-Receive Hooks help page.

Initial Eclipse Paho contributions completed

March 29th, 2012 - No Comments

At EclipseCon 2012 in Reston, VA this week, it was announced that both of the initial code contributions for Eclipse Paho are now available in the Eclipse code repositories. These comprise the source code for the production-level C and Java clients, which are currently shipped by IBM with WebSphere MQ.

What is Eclipse Paho? There’s a page on the wiki about this, but in brief, it’s part of a broader machine-to-machine (M2M) initiative at the Eclipse Foundation. Code is licensed under the Eclipse Public License (EPL).

For more on Paho, take a look at the project page and project wiki at Eclipse, which include links to the core paho-dev mailing list, Bugzilla, and the code repository where the C and Java clients can be found. Binary downloads will follow in future. There is also a public test broker instance at m2m.eclipse.org. An update on progress on the Paho project has been posted on Slideshare.

Other news at EclipseCon included demonstrations by Sierra Wireless of an end-to-end application using the Eclipse Koneki Lua Development Tools receiving data from Arduino sensors, via an MQTT broker to an Android application; a demonstration of the Eclipse-based test tooling for MQTT which Eurotech will be donating to the Paho project in the coming months; and an initial offer of the existing third-party Lua client to the Paho project. It’s exciting to see this kind of momentum behind this industry initiative, and the opening up of the MQTT client code.

Oh, and what does the word “paho” actually mean? Simple. It’s the Maori word for “broadcast”. So, tell everyone!

Eclipse Paho started, more clients and servers emerge

March 11th, 2012 - No Comments

After a slightly longer-than-anticipated proposal and setup period, the new Eclipse Paho project now has an initial repository containing the IBM MQTT C client (with the Java code to follow very soon). If you want to read more about it, Andy Piper has a handy blog post describing how to compile and test the C client code. Ongoing discussion happens on the paho-dev Eclipse mailing list. There’s also the forthcoming EclipseCon event in Reston, Virginia, where there will be a talk on MQTT as well as various meet ups and birds-of-a-feather sessions to discuss the Machine-to-Machine space.

As part of the same project, there’s now a public test “sandbox” of the mosquitto broker at m2m.eclipse.org – again, more information has been posted in the paho-dev mailing list.

In other “cloud” news, our friends over at Pachube are now beta-testing MQTT support. This is very cool. Pachube is a neat cloud service which lets you store and chart data in a variety of ways. Roger Light has posted a nice quickstart guide to MQTT and Pachube.

On the client side of things, Nick O’Leary has updated his very popular Arduino client. A new pure Python implementation has started over on Github, too.

As always, feel free to join us on IRC or on the protocol/community mailing list, update the wiki with your examples, or talk to us on Twitter to let us know what you think!

Community news and activity roundup

February 6th, 2012 - No Comments

It has been a really busy few months in “MQTT land” and there have been a lot of changes and updates – if you haven’t been following us on Twitter, Google+ or the mailing list, it might be worth recapping some of the news here.

Wiki

The mqtt.org wiki has had a thorough facelift – upgraded, new capabilities added, a mobile web UI, and a lot more information added. Over time, the static Documentation and FAQ pages will probably migrate there as well. We now have a section dedicated to the protocol itself including some of the clarifications and questions around the spec that have come up via the mailing list; a much more extensive page listing example uses; some ideas for people wanting to develop new “things”; and the coding examples section is being worked on (did you know there’s an iPhone example now?). Wikis work best with lots of contributors, so please help to build it up into a better resource – even if only to add some headings for new sections that you’d like to see created!

New implementations

The Software page continues to grow. That’s very awesome, as it means that more people get to try out MQTT in their languages of choice. There are device implementations for the Netduino and Nanode now, the node.js implementation has been significantly improved, there are some more Java implementations, and there’s also now a “plugins” section that lists extensions which add MQTT support to other runtimes.

Excitingly, there are also a couple of new broker implementations due soon – ELWIX (an embedded UNIX variant) is due to support MQTT in the next release, and Nirvana have announced early access to MQTT support in v7 of their messaging product.

Podcasts

A couple of podcasts featuring MQTT content came out during January:

Events (and Awards)

A quick round-up of recent and forthcoming events:

  • IBM announced a (funded) residency to write a Redbook on MQTT during March.
  • The first face-to-face meeting of the Eclipse M2M Industry Working Group took place in Hursley, UK, on January 31 2012. The Eclipse Paho roadmap was discussed (more on this to come).
  • EclipseCon takes place in Reston, Virginia, March 26-29 and will feature M2M/IoT content and birds-of-a-feather sessions.
  • MQTT on an Amazon Kindle (!) won the Innovation Award at the London Green Hackathon, January 28-29 – check it out!

Goodies!

If you’ve ever wanted a cool MQTT Inside sticker for your project, Ben Hardill has come up with a neat tool that uses the MOO API to enable you to self-serve purchase stickerbooks filled with them. That’s over on the new Goodies page, and the plan is to add more handy promotional schwag over there in time. What kinds of things should we make available? Let us know!

Eclipse Paho, Open Source, and other news

November 3rd, 2011 - 5 Comments

A big day for MQTT… “the little protocol that could”? :-)

Back in August, we mentioned the intent to take MQTT to a standards body – that process is in progress.

On November 2, IBM and Eurotech, the originators of the MQTT protocol specification, announced that they were joining Sierra Wireless and the Eclipse Foundation in a new Machine-to-Machine (M2M) Industry Working Group at Eclipse. Sierra Wireless have already contributed M2M frameworks and tooling to the proposed Eclipse Koneki project.

Today, November 3, IBM and Eurotech also announced the donation of Java and C MQTT clients to the newly-proposed Eclipse Paho M2M messaging project.

What does this mean? Well, to start off with, the IBM Java and C clients will be donated to the Paho project. The project proposal defines the ongoing scope as:

…to provide open source implementations of open and standard messaging protocols that support current and emerging requirements of M2M integration with Web and Enterprise middleware and applications.  It will include client implementations for use on embedded platforms along with corresponding server support as determined by the community.

In order for M2M device and client developers to integrate, develop and test messaging components end-to-end, Paho will address the development of frameworks and sample code needed to support testing and development of end-to-end device connectivity with a server. The project will make these available in an Eclipse M2M sever “sandbox”, as recommended by the Eclipse M2M Industry Working Group.

The Paho project scope includes the development of tooling that will support effective use, integration and testing of the messaging components.

This has created a lot of buzz, as tweets and articles we’ve been seeing today confirm. It’s great news, and we encourage everyone to join the Google Group for more discussion on the future of MQTT, or to watch the progress of Eclipse Paho and other related projects as they develop.

As always – we also thank everyone involved in the MQTT community for their passion and interest – it’s just amazing that there are so many implementations out there already. Here’s to the M2M space powered by MQTT!

 

PubSub Huddle

September 23rd, 2011 - 2 Comments

I presented on MQTT today at the PubSub Huddle event in London – a developer meetup for all those interested in messaging topics. 0MQ, RabbitMQ, SockJS (websockets) and other projects were all represented. You can watch the video of the talk on the Skills Matter website.

The talk included a short demo of how great MQTT can be to connect up tiny devices like Arduinos – I had my Arduino with a temperature sensor and an XRF module passed around the audience, and showed MQTT publishing the data via a simple Python script to my Really Small Message Broker. We also did a live link-up to an automated home system in IBM and showed that being controlled using MQTT over the web. Later in the afternoon I had a Wifly shield attached with the MQTT client running on the board, and clients running in C, Java, node.js, Python, and an Android app receiving the data concurrently.

There’s a real buzz around messaging at the moment, and it was great to see so many different people at the event. Lots of interesting folks around – including the author of the Perl and Ruby MQTT clients, Nicholas Humfrey. One piece of news from him is that the Ruby gem now has a new home on Github, so it’s worth checking out there if you are interested.

Finally – our new discussion group is up-and-running so do join us there if you’d like to talk about any MQTT-related topics!

Wikipedians unite!

A brief note to point out that MQTT is now represented by an entry on Wikipedia (thanks to one of our user community, @abusule) – feel free to help to maintain the information, and add citations and references as relevant.

Growing the MQTT community

August 26th, 2011 - 2 Comments

A couple of weeks ago it was announced that plans were being put in place to move the MQTT protocol forward for standardization, along with a call for participants to that process.

As part of that change, a number of things have been added “behind the scenes” on mqtt.org, including a new Get Involved page listing the different places where conversations happen – including a new MQTT discussion group that will be properly launched shortly. There’s also a new Twitter ID, @mqttorg, where site updates and other news is being posted.

The site design has been freshened slightly (including a nicer mobile interface), and the upper menu will be reorganized soon to make sure that the Get Involved community page is visible. Expect more use to be made of the wiki in future, too. There has been a huge growth in interest in the use of the protocol over the past few weeks, and it would be great if more people could share their experiences on the wiki and in the different discussion areas. Remember to let us know if you are doing anything cool with MQTT – tag your tweets #mqtt to make sure you get our attention!

One final piece of news… if you are in the UK and interested in learning more about MQTT then you should check out the free 1-day messaging PubSub Huddle on September 23rd, where MQTT will be one of the technologies being discussed.

MQTT used by Facebook Messenger

August 12th, 2011 - 4 Comments

This one has come slightly out of the blue. We’ve always known around here that MQTT is ideal for mobile messaging; the small-footprint, low bandwidth nature of the protocol helps to minimise both battery use and network traffic. Just what you want to stay connected.

Lucy Zhang, a software engineer at Facebook, has written about their new Facebook Messenger app:

One of the problems we experienced was long latency when sending a message. The method we were using to send was reliable but slow, and there were limitations on how much we could improve it. With just a few weeks until launch, we ended up building a new mechanism that maintains a persistent connection to our servers. To do this without killing battery life, we used a protocol called MQTT that we had experimented with in Beluga. MQTT is specifically designed for applications like sending telemetry data to and from space probes, so it is designed to use bandwidth and batteries sparingly. By maintaining an MQTT connection and routing messages through our chat pipeline, we were able to often achieve phone-to-phone delivery in the hundreds of milliseconds, rather than multiple seconds.

You can read her full post here.

[edit: of course, MQTT has also been used to build a Facebook "presence" device before, by our friends at Isidorey, but this new deployment inside Facebook is obviously something with much broader reach!]

Open Invitation to join the MQTT Standardization discussion

August 12th, 2011 - 7 Comments

MQTT has been around for over 10 years. It has seen many successful, wide-scale implementations in that time, too. Until now, the protocol specification has been shared between IBM and Eurotech, although it is published under royalty-free terms for ease of use, understanding and implementation.

Today, we’re delighted to announce that the specification will be moved toward formal standardization. Since so many groups, communities, and individual developers have expressed an interest, we’re also very excited to make this process open for anyone to join:

The MQTT protocol specification, in the public domain since 1999, was published under royalty free terms in 2010. New M2M solutions, fuelled by exponential growth in wireless device connections, bring the need for reliable and scalable messaging. To support industry growth and ensure open connectivity, Eurotech and IBM are planning to bring the MQTT protocol to a standards organization. We welcome your interest and participation in this standardization initiative.

You can download the full announcement (PDF), which includes details of who to contact in order to get involved.

MQTT and Android make great partners

August 1st, 2011 - 5 Comments

For some reason we missed updating the site when this was first posted, but Dale Lane wrote a fantastic blog post back in February highlighting how MQTT can be used for push notifications in Android applications.

He’s even included a thorough set of sample code and some detailed thoughts on how to optimise the way the application uses the Android system APIs. It is a great reference!

It doesn’t end there. Developers have been using MQTT and Android together for a while now. Ben Hardill created a simple Android app for monitoring the state of his TV. As well as that, the new Android device ADK, Android@Home, and the emergence of cool cloud services like Isidorey (another new addition to the Software page) that support MQTT natively, enable some extremely cool things. Folks continue to bridge cloud services like Pachube with MQTT, too – there’s great synergy there.

In the same way that the MQTT protocol has been ideal for minimising data usage on sensor networks in the past, it is a perfect partner for mobile applications, too.

… so… webOS or Windows Phone samples next, anyone? :-)

More client API goodness

July 29th, 2011 - No Comments

The Software page has just been updated to reflect the addition of a new Lua client API thanks to Andy Gelme aka geekscape.

Andy created the Lua library as part of his work on the Aiko platform, a way of joining up the Internet of Things being created thanks to Open Source hardware like Arduino and the ability to run Linux on platforms like OpenWRT. He also notes that it will run on a Playstation Portable! In theory it should also be possible to run on other platforms that support Lua scripting such as Android using the Android Scripting Layer (although some work might be needed to add the library to the SL4A environment).

The Software page now lists the client APIs in alphabetical order of language implementation, with the exception of the 2 device-specific implementations for Arduino and mbed. As the note at the top of the section says…

… not all of the client APIs … are current. Some are at an early or experimental stage of development, whilst others are stable and mature … some may not provide full support for all of the features of the latest MQTT specification.

It continues to be great to see developers working with the protocol and providing their APIs for others in the community to use. We’re happy to list them here on mqtt.org, so please let us know if you are working on anything that should be shared. Thanks for your contributions!

Related: the mosquitto blog has been updated with a post about the Lua client.

MQTT gets a landing page, and a video

July 29th, 2011 - No Comments

The IBM website has recently been updated to give WebSphere MQ Telemetry its very own “landing page” with more information about the product and how it interoperates with WebSphere MQ.

The MQonTV channel on YouTube also now has a nice video which talks about how MQTT can be used to connect the Internet of Things and a Smarter Planet. Take a look!

[youtube=http://www.youtube.com/watch?v=WVWAXnbnV3w&hd=1]

Finally, in case you missed them, MQTT was featured in a couple of IBM podcasts over the past 12 months. Check out the developerWorks podcast series, and the Connectivity and Integration podcasts (MQTT is featured in episode #3).

MQTT ported to the mbed platform

December 20th, 2010 - 2 Comments

One of the cool things about the MQTT specification being available for royalty-free implementation is that anyone can create their own clients (or brokers) for different and, well, more niche or “interesting” platforms. There has been an MQTT library available for Arduino for some time, but one of the cool alternative prototyping boards that has emerged recently is the mbed platform. Yilun Fan of the CEIT at the University of Queensland has just released an early version of a publish-only MQTT client which will run on the mbed (details also available in the mbed cookbook). He credits the inspiration for the work to Nick O’Leary’s Arduino client. If you have an mbed and have access to a breakout board with an Ethernet socket, then this will definitely be worth a look.

mbed

We’ve added the mbed client to the list of available clients on the Software page. If you are working on an implementation for a different platform, or just have an alternative to one that is already out there, do let us know so we can keep the community updated.

MQTT v3.1 specification available

August 20th, 2010 - 1 Comment

A protocol isn’t much use without a specification that allows others to understand how it works and how they can implement it. This has been a missing piece to the MQTT story for a while. The specification was originally made available as a part of the WebSphere Message Broker InfoCenter. This was done to get the protocol ‘out there’ with the intent that others could adopt it, but it came with the InfoCenter license that didn’t allow for others to implement it. With MQTT support moving from Message Broker to MQ, the protocol needed a new home.

One week ahead of the planned availability date of MQTT support in MQ, the MQTT v3.1 specification has been published on IBM developerWorks. This has been done with a royalty free license so anyone is free to create their own implementations.

You may notice the version has bumped to v3.1. There are some updates to the spec that adds support for security and clarifies the use of UTF-8 versus US-ASCII. The spec has also had a rewrite to make it a clearer and more complete document.

MQTT (definitely) coming to MQ

July 8th, 2010 - 10 Comments

IBM has formally announced its plans for bringing MQTT support to MQ. Unlike the preview announcement made previously, this includes the concrete details on what is being done, including the planned availability date – August 27th, 2010.

Known as MQ Telemetry, this will allow applications to use the MQTT v3 protocol to communicate with their MQ queue manager. A pair of client libraries are provided for applications to use, in both C and Java.

An advanced client is also provided – the MQ Telemetry daemon for devices. This is based on RSMB that was previously only available via IBM alphaWorks on an evaluation license.

A key part of this will be a much clearer statement on the use of the MQTT protocol itself – something the community has needed for some time.

The formal announcement is here and the MQ product pages have been updated here.

MQTT coming to MQ

April 28th, 2010 - No Comments

Yesterday, IBM made a preview announcement that brings good news to fans of MQTT:

IBM plans to offer a new optional feature for WebSphere® MQ to provide messaging designed for connecting smart sensors and telemetry devices. This new feature will enable existing WebSphere MQ applications and networks to connect with remote sensors and devices enabling connectivity to the edge of the enterprise, supporting sense-and-respond solutions that enable smart work. [...]

MQ Telemetry Transport (MQTT) support was previously provided by WebSphere Message Broker. This new optional feature reduces the prerequisites needed for Telemetry messaging solutions while still enabling WebSphere Message Broker to connect to sensors and devices leveraging this optional feature of WebSphere MQ.

Capabilities to include:

  • Optional feature for connecting telemetry devices like sensors and actuators
  • Support for MQTT protocol optimized for resource-constrained sensors and devices
  • Integrated configuration for telemetry messaging with WebSphere MQ Explorer Eclipse tooling
  • MQ Telemetry toolkit, clients, and samples

For more information, you can read the full announcement here.

10th Birthday Party

July 23rd, 2009 - 2 Comments

To mark the event of MQTT’s 10th birthday, we had a bit of a party for those that have been involved over the years. Arlen Nipper and Andy Stanford-Clark, the fathers of MQTT were there to tell the tale of how it all came to be.

All photos by Tony Whitmore.

Welcome-

July 20th, 2009 - No Comments

With MQTT celebrating its 10th birthday this year, we decided it was time that mqtt.org was given a face-lift. This new site should make it easier to find out what MQTT is and how it’s used.

There are also pointers to implementations of the protocol that are available – both official IBM products and community-written software.

If you have anything you’d like added to the site, please let us know: mqtt@mqtt.org.
