Hello,
I'm trying to create a connection between two universal apps. But i cant make them find each other.
Client side:
txtOutput.Text += "\nConnect() - Starting";
txtOutput.Text += "\nConnect() - starting searching for devices running this app...";
deviceServiceInfoCollection = await DeviceInformation.FindAllAsync(
RfcommDeviceService.GetDeviceSelector(RfcommServiceId.FromUuid(RfcommServiceUuid)));
txtOutput.Text += "\nConnect() - ended searching for devices running this app";
txtOutput.Text += "\nConnect() - starting processing list";
if (deviceServiceInfoCollection.Count > 0)
{
foreach (var device in deviceServiceInfoCollection)
{
txtOutput.Text += "\nConnect() - processing " + device.Name;
if (device.Name.Equals("MYPC"))
{
txtOutput.Text += "\nConnect() - MYPC found!";
}
}
}
}
From which im getting this output (even when i take my BL dongle off!! no errors!!):
Connect() - Starting
Connect() - starting searching for devices running this app...
Connect() - ended searching for devices running this app
Connect() - starting processing list
Server side:
private const uint ServiceVersionAttributeId = 0x0300;
private const byte ServiceVersionAttributeType = 0x0A;
private const uint ServiceVersion = 200;......
txtOutput.Text += "\nStartListen() - Starting";
provider = await RfcommServiceProvider.CreateAsync(
RfcommServiceId.FromUuid(RfcommServiceUuid));
txtOutput.Text += "\nStartListen() - provider received.";
StreamSocketListener listener = new StreamSocketListener();
listener.ConnectionReceived += HandleConnectionReceived;
txtOutput.Text += "\nStartListen() - listener received.";
await listener.BindServiceNameAsync(
provider.ServiceId.AsString(),
SocketProtectionLevel.BluetoothEncryptionAllowNullAuthentication);
txtOutput.Text += "\nStartListen() - bindServiceNameAsync.";
var writer = new DataWriter();
txtOutput.Text += "\nStartListen() - dataWriter created.";
writer.WriteByte(ServiceVersionAttributeType);
writer.WriteUInt32(ServiceVersion);
txtOutput.Text += "\nStartListen() - service version defined.";
var data = writer.DetachBuffer();
provider.SdpRawAttributes.Add(ServiceVersionAttributeId, data);
provider.StartAdvertising(listener);
txtOutput.Text += "\nStartListen() - started advertising.";
also:
private void HandleConnectionReceived(StreamSocketListener listener, StreamSocketListenerConnectionReceivedEventArgs args)
{
txtOutput.Text += "\nHandleConnectionReceived() - Starting";
provider.StopAdvertising();
listener.Dispose();
listener = null;
txtOutput.Text += "\nHandleConnectionReceived() - stopped advertising.";
this.socket = args.Socket;
this.dataReader = new DataReader(this.socket.InputStream);
this.Run();
}
private void Run()
{
txtOutput.Text += "\nRun() - Starting";
while (true)
{
try
{
txtOutput.Text += "\nRun() - starting reading";
uint stringLength = dataReader.UnconsumedBufferLength;
String message = (String)this.dataReader.ReadString(stringLength);
txtOutput.Text += "\nRun() - message read";
}
catch (Exception)
{
return;
}
}
}
From which i get (this time, when i disconnect the BL dongle, it wont run - which seems good):
StartListen() - Starting
StartListen() - provider received.
StartListen() - listener received.
StartListen() - bindServiceNameAsync.
StartListen() - dataWriter created.
StartListen() - service version defined.
StartListen() - started advertising.
(adapted from this example: http://www.silverlightshow.net/items/Windows-8.1-Play-with-Bluetooth-Rfcomm.aspx)
Also, in both manifests:
<Capabilities>
<Capability Name="privateNetworkClientServer" />
<Capability Name="internetClientServer" />
<m2:DeviceCapability Name="bluetooth.rfcomm">
<m2:Device Id="any">
<m2:Function Type="serviceId:(THE SAME ID BOTH WAYS)" />
</m2:Device>
</m2:DeviceCapability>
</Capabilities>
I also tried in client:
PeerFinder.AlternateIdentities["Bluetooth:PAIRED"] = "";
var devices = await PeerFinder.FindAllPeersAsync();
var device = devices.FirstOrDefault();
But it just gets stuck (with or without my BL dongle on), wont even get to the device line.
So what am i doing wrong? Can someone help please?
Thank you in advance!
