How to increase the max in IdGenerator from client? #123

Open Shraddha-gami-source opened 3 years ago

Shraddha-gami-source commented 3 years ago

On sending messages/ack it is showing QoS query is full Is there any way to increase the max in IdGenerator from a client itself?

Attaching the stack trace for more info.

Hi @Shraddha-gami-source

We can't increase a number of ids, because this is a limitation of MQTT protocol. Why do you have so many pending messages?
