Hello everyone, I am currently facing the following challenge and I would greatly appreciate any input. I apologise in advance if my questions sound stupid, I am just starting out :)

I need to send some very basic measurements to the AWS IoT Broker. The implementation core involves a (resource limited) PIC24F connected to a SARA G350 GRGSM-/GPRS-Module.

Currently I am able to establish and communicate over a direct link TCP/IP connection, using ATCommands within my C Code.

Would I be able to port the Embedded C Paho client on this PIC ? (I have approx. 1kB RAM left). If this idea is impossibe and considering that I only need to do something as simple as publishing like 3 bytes, which of the following approaches sounds more viable :


Trying to extract only the absolutely essential parts of the libs as functions

OR

Trying to manually create the needed MQtt packets as a series of bytes and send them over the (TLS/SSL secure) TCP/IP direct link I have developed?

Thanks,
Pavlos
