Unable to discover device by Type

[dough]

Using the ohNet C API, when I create a device list to discover all UPnP devices, following a successful CP start, I get device discoveries.

Code:

stb_list_handle = CpDeviceListCreateUpnpAll(&UPnPDeviceDiscoverSink, NULL, &UPnPDeviceRemoveSink, NULL);

However, if I create a device list for discovering a specific type of device, I get no discovery call back. I am a little confused about the type parameter in the API guide for the CpDeviceListCreateUpnpDeviceType function...
I have used it like this...

Code:

const char domain[]  = "schemas-upnp-org";
const char dv_type[] = "DigitalSetTopBox";
uint32_t   version   = 1;
                

stb_list_handle = CpDeviceListCreateUpnpDeviceType(domain, dv_type, version, &UPnPDeviceDiscoverSink, NULL, &UPnPDeviceRemoveSink, NULL);

...When using ohNetGen, the domain argument was the same as I have used here, but the "type" represented the type of service. On one UPnP browser I have, it shows "Device Type" as the complete URN. Like this:

Quote:urn:schemas-upnp-org:device:DigitalSetTopBox:1

Am I using this call correctly? Should I need to refresh the device list? Any advice is appreciated...

Sincerely,
Doug

Use "upnp.org" as the domain and "DigitalSetTopBox" as the type. The device list will handle the canonical -> upnp domain translation for you.
