[paho-dev] PINGREQ message timing.

[ನಾಗೇಶ್ ಸುಬ್ರಹ್ಮಣ್ಯ (Nagesh S) <nageshblore@xxxxxxxxx>]

Hi,
If a client receives a PUBLISH message from the broker - because it had subscribed to some topic - within the keepAlive number of seconds, should the client send the PINGREQ message ? I am not following the text in bold below; the text is from the spec.

The Keep Alive timer, measured in seconds, defines the maximum time interval between 
messages received from a client. It enables the server to detect that the network
connection to a client has dropped, without having to wait for the long TCP/IP timeout.
The client has a responsibility to send a message within each Keep Alive time period. In
the absence of a data-related message during the time period, the client sends a
PINGREQ message, which the server acknowledges with a PINGRESP message.
