Connecting and publishing

[mladedav]

Hi, I really like the library and I'm trying to use the master version (which I noticed is considerably different from 0.3 which is latest), but I can't seem to be able to publish. The problem seems to be in that the connection is never established, so all the publish calls are silently dropped (might I suggest logging that?) but I have not seen any API for connecting.

Can you point me to the correct function to establish a connection so that I can publish messages to a broker?

For the record, I have found out that calling Minimq::poll() several times helps, but I believe there should be some other way to start the connection.

Hi there @mladedav! The current design requires that poll() is called continuously in a low-priority task to execute the MQTT state machine. If poll() is not called regularly, the MQTT connection will not be established and publish() calls will be silently ignored.

You're right that the docs here are lacking - I've noticed even myself forgetting this fact sometime. I'll look at a way to make this more obvious.
