Question

我需要使用wifi直接连接Windows设备。我们的应用是cordova应用。下面是我写的wifi直接广告的代码。执行m_Publisher后，完整的代码执行无错误，start()状态会发生变化。但其他设备仍无法看到WiFi Direct设备。

function enableStartWiFiDirect() {

    var Api_DeviceName = Windows.Networking.Proximity.PeerFinder.displayName;
    m_Publisher = Windows.Devices.WiFiDirect.WiFiDirectAdvertisementPublisher();
    m_Listener = new Windows.Devices.WiFiDirect.WiFiDirectConnectionListener();

    m_Listener.addEventListener("onconnectionrequested", onConnectionRequested);

    m_Publisher.advertisement.IsAutonomousGroupOwnerEnabled = false;

    m_Publisher.advertisement.ListenStateDiscoverability =
        Windows.Devices.WiFiDirect.WiFiDirectAdvertisementListenStateDiscoverability.Normal;

    var IE = new Windows.Devices.WiFiDirect.WiFiDirectInformationElement();

    // IE blob
    var dataWriter = new Windows.Storage.Streams.DataWriter();
    dataWriter.UnicodeEncoding = Windows.Storage.Streams.UnicodeEncoding.Utf16LE;
    dataWriter.writeString(Api_DeviceName);
    IE.Value = dataWriter.detachBuffer();


    // OUI
    var dataWriterOUI = new Windows.Storage.Streams.DataWriter();
    dataWriterOUI.writeBytes([0xAA, 0xBB, 0xCC]);//(Globals.CustomOui);
    IE.Oui = dataWriterOUI.detachBuffer();

    IE.ouiType = 12;//(byte)Api_DeviceName.Length;

    m_Publisher.advertisement.informationElements.push(IE);

    m_Publisher.start();
    console.log('WiFi Direct Started');

    return "Advertisment started sucessfully";
}

希望有人可以帮我解决这些问题。任何帮助将不胜感激

我可以在cordova应用程序中从下面启动WiFi Direct广告。

startAdvertisment: function (successCallback, errorCallback, args) {

        if (publisher === null) {
            publisher = Windows.Devices.WiFiDirect.WiFiDirectAdvertisementPublisher();
        }

        if (listener===null) {
            listener = new Windows.Devices.WiFiDirect.WiFiDirectConnectionListener();

            listener.onconnectionrequested = OnConnectionRequested;
        }
        publisher.advertisement.isAutonomousGroupOwnerEnabled = false;

        publisher.advertisement.listenStateDiscoverability =
            Windows.Devices.WiFiDirect.WiFiDirectAdvertisementListenStateDiscoverability.normal;
publisher.start();

    }

适用于Cordova Windows平台的WiFI Direct
