I've found the library posted above and I was trying to implement the library within my project to create my JSON payload that was to be sent to the cloud. I was previously using the CJSON library which was a very simple library to use however this gave issues within my application and was causing the unit to crash. Hence I wanted to try this library as it was more embedded specific.

What I've tried so far:

User's image

Then tried using the MQTT client publish function to send the data which I've added to the buffer and also print it to the Segger_RTT viewer:

User's image

However nothing is sent or printed to the console, a push in the right direction would be greatly appreciated as I'm new to using RTOS and is probably something I've not understood from the documentation.

Thanks,

CF.

    Hello cf_tru_mmu,

    What is the size of the payload? did you try a smaller payload size, just wanted to make sure if this is not the issue?
