Hello Experts,

I have a query concerning how to avoid duplicate messages arriving at Mqtt client. Even detection of a duplicate message will help me.

My question is as below ...

I am using eclipse paho android client (version : 1.0.2). MqttAndroidClient object is initialized with default Auto Acknowledge mode
and clean session = false.

However, on reconnection to broker , I receive "previously received" mqtt messages again with "duplicate = false"
I was expecting that messages should not be redelivered or should be sent with flag "duplicate = true". But , it is not the case.

Please help.
