MQTT uses a TCP/IP connection that is normally left open by the client so that is can send and receive data at any time.
But what happens when or if the connection fails?
To detect a connection failure MQTT uses a ping system where it sends messages to the broker at a predetermined interval if no messages have been sent after a certain period (KeepALive)
In this tutorial will explain what keep alives are for and we will take a detailed look at PINGREQ and PINGRESP examples.
We will also see what happens when keep alive messages fail.
