Hi, I had an odd incident today where one of my sensors running arduino/esp8266 and lmroy pubsubclient was seemingly connected to the mosquitto server and sending publishes, in my loop I have if (client.connected()), but at the broker side, the last log entry at the time the sensor went down shows a socket error disconnect.
Im wondering how the pubsubclient could go on thinking it was connected and be making pubs for hours while in fact it was not "connected" at the broker side?
Is this the same issue as mentioned where we should really be checking the return value of client.loop() and reconnect if it fails? If so whats the point of client.connected()?
