Sub 1 GHz Wi-Fi examples

I have my BeaglePlay up and running, it is working great and so far very happy with the performance. I am able to connect using the standard Wi-Fi and Ethernet methods, but now I need to transition to the Sub 1 GHz Wi-Fi connection and test the range limitations for my application.

Has anyone got this functionality working yet? Please provide tutorials or links to GitHub repos.

Thank you!
