To help you understand how OpenDOF requestors and providers work using C, we’ve placed source code for a “helloWorldProvider” and a “helloWorldRequestor” in a GitHub repository for you to play with. You can access it here.

If you want to use the cst-iot-service as the OpenDOF router, you will need to (1) set the credentials and the IP address for the IoT service in the helloWorldRequestor.c and helloWorldProvider.c source files, then (2) build and run the applications.
