Disconnect exactly every minute and also When publishing message about mqtt_client HOT 5 CLOSED

Hmm, this sounds like the default keepalive period(60s), try setting this to a lower value, i.e.

client.keepAlivePeriod = 20;

from mqtt_client.

@shamblett yes that's it. But it seems the behavior is wrong.

Ok, in what sense, do you mean the behaviour is wrong? 60 seconds seems a fairly common value, some of this depends on your broker of course. A value of 0 disables keep alive, is this what you would prefer as a default?

Ahh i was wrong, i thought that connection should be always up and Automatically reconnect when disconnected, as i seen in Paho.

It seems this package works properly (http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html#_Toc385349238).

But I think it should disconnect client only if it is idle for keepAlive time. (not sure if receiving packet count as activation).

Anyway thanks for your perfect job.

OK, no probs, closing
