java – 执行UPNP扫描不返回飞利浦色相桥

我在端口1900发送一个数据包到239.255.255.250,我发送以下数据：

M-SEARCH * HTTP/1.1
Host: 239.255.255.250:1900
Man: "ssdp:discover"
MX: 10
ST: ssdp:all

只需要进一步的信息,在我的Java代码(Android)我有以下,但我得到相同的响应作为数据包测试程序应用程序：

try
        {
            byte[] sendData = new byte[1024];
            //byte[] receiveData = new byte[1024];
            byte[] receiveData;
            String mSearch = "M-SEARCH * HTTP/1.1rnHost: 239.255.255.250:1900rnMan: "ssdp:discover"rnMX: 10rnST: ssdp:allrnrn";
            sendData = mSearch.getBytes();

            DatagramPacket sendPacket = new DatagramPacket(sendData,sendData.length,InetAddress.getByName("239.255.255.250"),1900);

            DatagramSocket clientSocket = new DatagramSocket();
            clientSocket.send(sendPacket);

            while (keepGoing)
            {
                receiveData = new byte[1024];
                receivePacket = new DatagramPacket(receiveData,receiveData.length);
                clientSocket.receive(receivePacket);

                String response = new String(receivePacket.getData());

                if (response == null || response.length() == 0)
                {
                    keepGoing = false;
                }
                else
                {
                    iupnpScan.updateText(response);
                }

            }
            iupnpScan.complete(true);
            return true;
        }
        catch (UnknownHostException ex)
        {
            Log.e("MainActivity","Unknown Host Exception: " + ex.toString());
        }
        catch (SocketException ex)
        {
            Log.e("MainActivity","Socket Exception: " + ex.toString());
        }
        catch (IOException ex)
        {
            Log.e("MainActivity","IO Exception: " + ex.toString());
        }
        iupnpScan.complete(false);
        return false;

我正在收到一些设备回来,比如我的智能电视,路由器和NAS,但是Phyips Hue Bridge从来没有在回复中返回.

飞利浦色相桥是否实现了UpNP的不同之处,我可以看到,现在所发现的响应是什么,需要什么才能找到.

谢谢
