Issue receiving large mqtt packets. Can we change max packet size? #491

Hi,

I am using mqtt over a9g module. I am trying send a large audio file of about 35kb. But the payload gets broken down into 128 byte packets and are received one by one. Major issues is that it takes over 25 sec for complete reception.

How can this be solved? Any way to change maximum payload size so as to increase it?
