April 22, 2014 (Project Leader Call)


  1. Review plans for Java stack launch - Launch plan
  2. Build support for Windows and OS/2 - Reference bug 415757
  3. New sandbox servers for CoAP and Lightweight M2M
  4. Other questions and issues from project leaders


  • Ian Skerrett
  • Kai Kreuzer
  • Mattias Kovatsch
  • Jens Reimann
  • Marco Carrer
  • Jan Rellermeyer

IoT Java Launch

  • Review [draft plan]
    • Discussion about what are the packages and key deliverables. It was decided we have two main deliverables: 1) A set of foundation building blocks for IoT Java developers, including Paho, Calfornium, Kura and Concierge. 2) Solutions for IoT, including a solution for Industrial IoT in Eclipse SCADA and a solution for home automation in Eclipse SmartHome. These solutions make use of the foundation building blocks. NOTE: OM2M might be another solution for Telecos?
    • Discussion about the demos. The target will be to have at least 3 demos: 1) Green house demo that shows the foundation building blocks using Kura, MQTT, CoAP, etc. 2) Eclipse SmartHome demos and 3) Eclipse SCADA demo. The goal is to show each of these demos sharing data via MQTT and CoAP. Also show a consistent programming model using OSGi and Concierge.
    • Discussion about deployment targets. Initial target will be Raspberry Pi and BeagleBone but this might need to be refined.
    • ACTION ITEM: Ian will update the plan based on this discussion.

April 8, 2014 (WG call)


  • New time for the bi-weekly call
  • Ecosystem page on update
  • Java for IoT – with many Eclipse IoT projects running on Java, it would be nice to discuss what can be done to improve and demonstrate our Java end-to-end story

  • Benjamin Cabé
  • Ian Skerrett
  • Hilary Thomasson
  • Linda Ariani Gunawan

New time for the call

  • It's proposed to have the call 2 hours later (and not necessarily on a Tuesday), in order to allow participant in Pacific time to join
  • ACTION ITEM: Benjamin will send a Doodle poll

Ecosystem webpage

  • Web page will go live at the end of the week
  • ACTION ITEM: Benjamin to put the page live, and send a mail to the mailing list

Java for IoT

  • Good progress on the technology side – great story for Java developers
  • Ian would like to put together a plan for JavaOne: tutorials, documentation, deliverables
  • Hilary: Eurotech will be at JavaOne
  • Marco: we should start a wiki page
  • We should target more interoperability demos
  • ACTION ITEM: Ian/Benjamin -> create a wiki page

IoT Events

April 1, 2014 (Project leads call)


  • Build infra and integration needs
  • Java demo at JavaOne
  • Misc


  • Benjamin Cabe
  • Ian Skerrett
  • Kai Kreuzer
  • Mattias Kovatsch
  • Scott Lewis
  • Ian Craggs
  • Jurgen Rose
  • Jens Reimann
  • Mahdi Ben Alaya

Build Infra

The goal was to discuss what projects do today for building for MacOSX, Windows, ARM, ... and what could be done to simplify project lives.

  • Getting an Equinox launcher for ARM sounds like something that would be useful to projects like SCADA and possibly SmartHome (Equinox is bootstraped manually when SmartHome runs on e.g. Raspberry Pi)
  • Build for Windows and Mac
    • Eclipse SCADA is using Hudson Windows slave to build signed MSI installers for Windows
    • ACTION ITEM: Benjamin will discuss with Eclipse Webmaster what is the best practice for Win and Mac build (Hudson slaves seem to be for testing only)
  • Signing
    • Eclipse SCADA is building RPM and DEB packages already
    • There is no proper solution for signing such packages which need to be signed using gpg
      • ACTION ITEM: Benjamin to coordinate with Eclipse Webmaster to discuss the opportunity of using gpg for signing linux packages
    • It appears interesting to provide debian or rpm package repositories at Eclipse in a central way
      • ACTION ITEM: Benjamin to coordinate with Eclipse Webmaster to discuss thoughts on package repos.


  • Ian explained that it would be great to have a nice demonstration of our Java story for JavaOne in September
  • Idea would be to start collecting thoughts for a really compelling Java story, and start producing articles, demos, tutorials, ... for JavaOne
  • Kai Kreuzer details his vision for a SmartHome demo
    • already discussing with Jan from Concierge to get SmartHome running on Concierge
    • Paho is already being used, if Moquette comes to Eclipse SmartHome could also repackage an MQTT broker
    • Kai discussing with Marco on how to integrate w/ Kura
  • Jens explains that SCADA also plans on doing a demo together with eTrice and 4DIAC, targetting end-Sept
    • demo would be something more industrial, using Modbus
  • Scott Lewis described that ECF's implementation of standards-based OSGi Remote Services currently runs on Concierge (or any R5 OSGi framework), and that ECF has an MQTT remote services provider currently based upon the Paho Java Client. Given this, and the existing tutorials and examples, it would be straightforward to put together a JavaOne demo...perhaps even for/with SmartHome...based upon Concierge, OSGi Remote Services, and MQTT...with standardization/interoperability being operative at all levels (OSGi framework, remoting/distribution, and messaging protocol/transport).
  • ACTION ITEM: Ian will put together a plan of what could be done for JavaOne
    • Of course projects will have to be willing to provide support and help on actually implementing demos


  • Mattias explains he's now ready to contribute Californium to Eclipse, the current code base being now "frozen" after successful participation to IETF CoAP interop testing event.
  • Kai is interested in having CoAP support in SmartHome
  • Mahdi lets us know that two students are currently working on 1/ a CoAP Californium binding in OM2M and 2/ an Eclipse SCADA integration
  • Everyone is invited to use the WG mailing list to post updates on cross-IoT-project work on the mailing list to encourage collaboration and sharing of knowledge

February 11, 2014


  • Live demos on the website
  • Ecosystem promotion on the website
  • Eclipse IoT/M2M Rebranding update


  • Benjamin Cabé
  • Mattias Kovatsch
  • David Sciamma
  • Julien Vermillard
  • Jens Reimann
  • Andy Piper
  • Jurgen Rose
  • Ian Skerrett
  • Hilary Tomasson

Live demos

  • The Eclipse IoT website should help demonstrate and showcase the open-source IoT technologies available at Eclipse. Benjamin suggests that project leads should think about the demo they'd have to contribute
  • Jens: SCADA team has a limited bandwidth to work on a live demonstrator over the next couple weeks
  • Eurotech
    • It's been discussed to try to have an always running version of the people counter. Hilary will synchronize with Marco
  • Mattias: it is hard to provide live/web demos of CoAP. Video would be an option
    • A test server could be hosted on, and you could download Copper for Firefox (CoAP plugin) for doing some tests
  • Benjamin suggests to have videos of the projects that are diffcult to demonstrate live
  • ACTION ITEM: Hilary/Marco and Ian to discuss about people counter demo
  • ACTION ITEM: Ian to ping Bitreactive regarding what demo content they would have
  • ACTION ITEM: Benjamin to follow up with Mattias to setup a CoAP sandbox server at

Ecosystem promotion on the website

  • The ecosystem webpage draft available at
  • After a discussion between Hilary and Ian, it's agreed to rework the page to list the Steering Committee members at the top of the page
  • Ian: each member company needs to provide product description, and company description
  • Mattias: could we provide an overview of the building blocks that are part of the ecosystem?
  • Ian: we need to create a better presentation of what the projects do together
  • ACTION ITEM: Benjamin to update ecosystem webpage to list SC members at the top
  • ACTION ITEM: Ian to ask members to provide content on the WG mailing list

Eclipse IoT/M2M Rebranding update

  • ACTION ITEM: Ian to create iot-wg mailing-list and subscribe everybody who's on m2m-iwg to this new list

Additional topics

Google Summer of Code (GSoC)

  • Google has a program for university students. Students are being paid for working on OSS projects (4500USD per student)
