MQTT publish large message


I’m using Quectel EG91 to connect mqtt and its working. I know the maximum length of the message is about 1500 byte, however I want to publish the large message (over 5000 byte). Any way I can do that?

Thank you.

hello test2012vnz, thanks for your question
Our standard module has a maximum sending limit of 1500 Byte, you can try add a teminator as a symbol of data send end in your program, thank you.
