For BLE you don't need anything like an URL. You need the ID of your BLE device so you can connect to it, but thats it.
The black board is a PRoC BLE, the red on a PSoC BLE (I think this is explained in the user guide).
A good example is the CySmart Android application, someone posted the sources here recently.
Well, I made some search and in this example they use a kind of serverUrl http://www.bluecove.org/bluecove/apidocs/overview-summary.html.
I will take a look at these codes that you said, because I think It is going to be more clear after I see an example directed to PSoC Ble 4.
