For AWS mqtt, you can see here

Connecting wp77 to AWS IoT

yes, I did get the AWS SDK for embedded C, did create the app, component and used pretty much the source code from them with just some small adjustments. Only problem I had was with the port, which I had to change from 8883 to 443 for the TLS to work properly. So, once the cm data is connected, I can connect subscribe and publish to the AWS backend. Haven`t done anything fancy really, just implemented the SDK as it came from AWS website, then compiled for the wp77xx target.
