B4R Question Async MQTT client?

[BertI]

On attempting to connect to an MQTT broker I'm finding if the broker is not available it takes around 10s for the MQTT client to exit (give up) from its connection attempt, in other words if you are attempting reconnects you get 10s blocking periods. Is there a way to implement an asynchronous connection? Or anyone suspect that I might be doing something wrong in the first place? I'm using rMQTT_ex V1.02 and know there is a setsocketTimeout function but not relevant to this aspect as far as am aware.
