How to increase the max in IdGenerator from client?

[Shraddha-gami-source]

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?
