I've just uploaded Smack 4.1.8 and 4.2.0-beta2 to Maven Central.

 

Smack 4.1.8 fixes a few minor issues and is expected to be the last release of the 4.1 branch. As always, Smack releases with the same major and minor version numbers are drop in replacements. Ideally you just need to change a single variable somewhere in your build system.

 

Smack 4.2.0-beta2 is the latest beta of Smack's current development branch. Notable additions include support for XEP-0313: Message Archive Management (MAM) and the IoT XEP series.

Starting with b91978dcc4ae partial support for the IoT XEPs was added to Smack. The XEPs consists, amongst other XEPs, of

  • XEP-0323: Data
  • XEP-0324: Provisioning
  • XEP-0325: Control
  • XEP-0347: Discovery

The XEPs are in experimental state, which means changes to them are possible.

Smack does currently only support a partial set of the mechanisms specified, especially when it comes to Data and Control. For example only boolean and integer values can be read and written But support for more data types can be easily added.

 

The IoT API for those XEPs is available in the latest snapshot builds of Smack, which are available via Maven Central's snapshot repository.  A quick start guide can be found here.

 

The development of the API was sponsored by Clayster.

Clayster creates technology to secure trust in the transactions between physical and digital entities, and strives to be that generic foundation for your physical assets digital life.

Clayster has an IoT discovery and provisioning platform supporting XEP-0347 and XEP-0324. The platform is available for those who are interested to explore XMPP and IoT further.  If you don't want to run your own infrastructure, Clayster is able to provide an XMPP Server and the discovery/provisioning platform for you. Feel free to reach out to rikard at clayster.com if you are interested to learn more about using XMPP for your next IoT project. www.clayster.com
