WiFiDirect cppwinrt misplaced '}' about windows-universal-samples HOT 3 OPEN

I also saw this problem. After you fixed it, do you get the GO and GC connected?

I believe so. I worked more with the C# sample. So see also #1399.

Best way of testing is to make sure the devices aren't already paired and get the C# sample working first.

Life will be better if you make this change to Scenario2_Connector.cpp at approx. line 78.

            deviceWatcher = DeviceInformation::CreateWatcher(deviceSelector, { L"System.Devices.WiFiDirect.InformationElements", L"System.Devices.Aep.CanPair", L"System.Devices.Aep.IsPaired" });

It will make it correctly report the pairing status for the device you are connecting to and stop it from trying to pair when already paired (which fails).

          co_await clientSocket.ConnectAsync(remoteHostName, ServerPortString);

is throwing an exception for me at the moment, but it does make the WiFi Direct connection, but I haven't run this code for a couple of months.

I let all the GO settings default and add "Push button" configuration methods on both sides. I suggest trying this first.

Note that the Advertiser only advertises for a couple of minutes and the Connector only looks for a few seconds. Once it says the enumeration is complete, you won't see any more devices until you stop/restart the watcher.

You are better off doing this:

		WiFiDirectDevice wiFiDevice = WiFiDirectDevice(nullptr);
		hstring selector = wiFiDevice.GetDeviceSelector(WiFiDirectDeviceSelectorType::AssociationEndpoint);

		co_await resume_background();
		DeviceInformationCollection devices = co_await DeviceInformation::FindAllAsync(
			selector,
			{
				L"System.Devices.Aep.CanPair",
				L"System.Devices.Aep.IsPaired",
				L"System.Devices.WiFiDirect.InformationElements"
			}
		);
		co_await winrt::resume_foreground(_queue);

every 30 seconds or so while you aren't suspended.

@orineman After look at your reply and the link you mentioned, I realize that only GC needs to do DeviceInformationCustomPairing::PairAsync(...), then both side can get a valid IP address and ping each other. But the problem is that how to use WiFiDirectConfigurationMethod::DisplayPin and ProvidePin? PushButton is kind of unsafe.
I don't see WiFiDirectConnectionParameters::PairingRequested call back handler get called at any situation.
I mentioned this problem in issue #1406
