Re: [paho-dev] MQTT v5 - Interop

[Ian Craggs <icraggs@xxxxxxxxxxxxxxxxxxxxxxx>]

Thanks Christoph, I was about to talk about MQTT v5 activities.  As well as server/client development, we should take this opportunity before the specification is finalized to feed back suggestions to the OASIS Technical committee.  The mailing list is here:

https://www.oasis-open.org/committees/comments/index.php?wg_abbrev=mqtt

There will be a 90 day period public review period soon, before it is finalized, but the sooner any comments are made, the better.  Once the specification is finalized, we'll have to live with the consequences for a long time!

James has completed a Java MQTT packet library, and aims to build on that for a complete client.  We took the view that a totally new client was appropriate, given the differences in the standards, and that the old client had so much historical baggage.  It does mean that an application would have to be coded differently from V5 to V3, but the extra features in V5 are substantial, so that writing common code for both V5 and V3 is probably not worthwhile.

Ideally, I would like to get a V5 Paho (Python) test broker up and running as soon as I can, but that will depend on my ability to fit it in.  (James has just offered to help me with that.)

I think the community would benefit from an status update on v5 implementation projects and interoperability testing opportunities.

To make a start for MQTTClient Objective-C https://github.com/ckrey/MQTT-Client-Framework :

- I assume the v5 spec to be quite stable.

- I will start implementing client side v5 now and will use any publically available broker for testing.

Cheers
