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 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

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 – 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!
