StreamingHueClient.Connect() Timeout

[richardoliverpearce]

Hi, I believe this is a bug - please correct me if I'm wrong (using Q42.HueApi.Entertainment 3.8.1). My Philips Ethernet Bridge is updated to the latest version (1810251352). I've just tried the sample in the source code and it exhibits the same problem.

I'm getting a TimeoutException thrown when trying to call StreamingHueClient.Connect(). Please find the stack trace below:

internal_error(80) ---> System.TimeoutException: The operation has timed out.

   at Q42.HueApi.Streaming.Connection.UdpTransport.Receive(Byte[] buf, Int32 off, Int32 len, Int32 waitMillis)
   at Org.BouncyCastle.Crypto.Tls.DtlsRecordLayer.ReceiveRecord(Byte[] buf, Int32 off, Int32 len, Int32 waitMillis)
   at Org.BouncyCastle.Crypto.Tls.DtlsRecordLayer.Receive(Byte[] buf, Int32 off, Int32 len, Int32 waitMillis)
   at Org.BouncyCastle.Crypto.Tls.DtlsReliableHandshake.ReceiveMessage()

The example code causing this exception is (very heavily inspired from your streaming documentation):

    class Program
    {
        static void Main(string[] args)
        {
            var applicationName = "applicationName";
            var deviceName = "deviceName";

            Task.Run(async () =>
            {
                var bridge = (await new HttpBridgeLocator()
                        .LocateBridgesAsync(TimeSpan.FromSeconds(5)))
                    .First();

                var localClient = new LocalHueClient(bridge.IpAddress);

                var appKey = await localClient.RegisterAsync(applicationName, deviceName);
                var streamingKey = (await LocalHueClient.RegisterAsync(bridge.IpAddress, applicationName, deviceName, true)).StreamingClientKey;

                var client = new StreamingHueClient(bridge.IpAddress, appKey, streamingKey);

                var all = await client.LocalHueClient.GetEntertainmentGroups();
                var group = all.First();

                var entGroup = new StreamingGroup(group.Locations);

                await client.Connect(group.Id);
            }).Wait();
        }
    }

You're registering your application twice with RegisterAsync and using the appkey and streamingkey from different app registrations.

This should work:

var registration = (await LocalHueClient.RegisterAsync(bridge.IpAddress, applicationName, deviceName, true));
var appKey = registration.Username;
var streamingKey = registration.StreamingClientKey;

Hi Michiel, you are absolutely right, I'll close the issue now thanks.
