Unable to get properties of remote device

[lovefamilyC]

I obtained the remote VTS device through the code and it showed that the communication was successful, but when getting the device object property value, a timeout exception occurred. code show as below:

public class TestMy { public static void main(String[] args) throws Exception { //创建一个虚拟设备 用于与设备交流 广播地址"255.255.255.255",端口47809 IpNetwork network = new IpNetworkBuilder() .withLocalNetworkNumber(0) //第二从参数是子网掩码位数 .withBroadcast("255.255.255.255",24) //.withBroadcast("192.168.1.255", 24) //.withSubnet("192.168.1.174",24) .withLocalBindAddress("192.168.1.174") //配置第一个网络，确保我们设置了重用地址 .withPort(47808).withReuseAddress(true).build();

    Transport transport = new DefaultTransport(network);
    LocalDevice ld = new LocalDevice(1, transport);
    ld.initialize();
    //创建设备结束--------------
    ld.startRemoteDeviceDiscovery();

    //通过地址、设备号 获取远程设备属性
    RemoteDevice rd = ld.getRemoteDeviceBlocking(10);

    Map<PropertyIdentifier, Encodable> values = RequestUtils.getProperties(ld, rd, new ObjectIdentifier(ObjectType.device, 10), null,
            PropertyIdentifier.objectList);

    System.out.println(values);

    ld.terminate();

}

}

You need to bind to the wildcard address to receive UDP broadcast responses. 0.0.0.0

Discovery does a WhoIs which is a broadcast request. Its likely that you aren't seeing the responses.
