Re: [paho-dev] PINGREQ from Eclipse Paho client ?

[Dave Locke <locke@xxxxxxxxxx>]

Hi, 
I have modified the Java client to remove
the 10 sec restriction on both KeepAlive and Connect timeout. Will sync
across to the master repository in the next few days

All the best 
Dave

Hi Nagesh

The client handles the PINGREQ internally - there is nothing you have
to do to trigger a PINGREQ to be sent.

The javadoc for MqttConnectOptions.setKeepAliveInterval clearly says this:
  @throws IllegalArgumentException if the interval is less than 10
seconds.
.. which it is in your code.

That said, from a comment Arlen made (I've lost track where exactly..
perhaps over on the mqtt google group), I think we need to remove this
artificial restriction in keepAlive value in the client. I'll try to
figure out where/how to raise an issue on the paho bugzilla for this.

Cheers,
Nick
