Maximum payload allowed for MQTT client (from knolleary).

Projects Programming

Hello,

I have written a MQTT client program which publishes a few remote parameters via MQTT. Now concatenating all the parameters to one string to publish gives me a string length of 117. Sniffing with wireshark shows me an added 16 bytes (total 133). But exceeding beyond that size, not far but to about 160, resets my network connection and the setup runs all over again and goes on. Many a times it refuses connection to the boker.

Any help on this.. Thanks. Will be happy to post a code snippet if required.

Don't bother. Now, posting all of your code is a different story.
