CC3235S: Starting out on mqtt_client example

Dear all

That's probably a stupid beginner question, but I'd be glad to have some help.

I can build and download the mqtt_client example onto the Launchpad_cc3235S. I wanted to follow the instructions from the readme. It says to fill the networking data into network_if.c

I found that file in the SDK source code

TI\ccs1230\simplelink_cc32xx_sdk_7_10_00_13\examples\rtos\CC3220S_LAUNCHXL\demos\mqtt_client_server

Do I need to copy this file into my project? I was actually hoping, that the demo explains how the driver and library structure is meant to work.

Any help appreciated

Chris
