Re: [mqtt-comment] Public review comments for mqtt-v3.1.1-csprd02: Figure 3.5 Keep Alive bytes

Hi Paolo,

Our broker’s timeout is set to 30 seconds. It would be nice to specify this more clearly, or at least suggest a value.

From this :

“If a Client does not receive a PINGRESP Packet within a reasonable amount of time after it has sent a PINGREQ, it SHOULD close the Network Connection to the Server.”

How much is “reasonable” amount of time ?

In the actual spec 3.1 the clients has a timeout equals to keep alive period to wait PINGRESP message.

Best regards.
