There’s an updated version of the Arduino MQTT client available. This fixes a bug where if the client lost its connection, you had to explicitly call disconnect before you could reconnect.

Not a major issue, but one that had caught a few people out.

    Would this be possible to get working with a username(DEVID)/password(APIKEY) like in MQTT v3.1? I have GO code that is somewhat similar, but can’t quite get it working.

    Hi Frank,

    it certainly is possible to add username/password support to the client. It hasn’t been high on my to-do list as I’ve tried to keep the size of the code to a minimum and no-one has needed it so far. I’ll have a play.

    Out of interest, what are you using on the server side?

    Thanks! It’s a bit crazy on the server side -> GO MQTT broker, with a codeigniter API allowing access to a Cassandra database. Basically, I’m trying to push data from lots of Arduinos, and I need some security.

    Another question. How difficult would this be to get working with any of the wireless shields (wishield?), at least for publishing/subscribing (no will)? Just some modification to Psub.h, it looks like?
