Your (Desktop)Release throws a ‘System.NotImplementedException’ when I try to discover devices. Using the dll in my own application shows, that the reason for the exception can be found in the BluetoothEndPoint Class.

For some reason a vital piece of code was cut from the build packaged with the desktop example. This was causing the BluetoothEndPoint.Create method to fail. I’ve placed an updated version of the zip file online to correct this.

The ObexFileTransfer service only initiates a connection to the required service on the receiving device, there isn’t a wrapper to do all the Obex communication (yet at least). Note you should use ObexObjectPush for an outgoing file push.
This article describes implementing the OBEX protocol over IrDA so the same applies when using Bluetooth:-

thank you for the link. I’ve tried to translate the connect part into c#, but it doesn’t work.

I’ve used the following byte array for the obex connect
byte[] tSendByte = new byte[MAX_SEND_BUFF_LEN];
tSendByte[0] = OBEX_CONNECT;
tSendByte[1] = 0x00;
tSendByte[2] = 0x07;
tSendByte[3] = OBEX_VERSION;
tSendByte[4] = OBEX_CONNECT_FLAGS;
tSendByte[5] = 0x08;
tSendByte[6] = 0x00;

and send it in this way
Stream stream = client.GetStream();
stream.Write(tSendByte,0,tSendByte.Length – 1);

The only response I get is 0xC0(192) = Bad Request. (of course the response is 3 bytes long 192 0 3)
I don’t see any mistake in my connect-array, is it possible that the bluetooth implementation has an error?
