Which service do you want to use on the phone?  OPP to push a file to it, FTP to get a file from it, or perhaps SPP to connect to its modem?  See e.g. http://www.alanjmcf.me.uk/comms/bluetooth/Bluetooth Profiles and 32feet.NET.html

What service did you use in the Connect call??  What error (i.e. exception) occurred?

I would like to send be Bluetooth in me PC a file to me phone a service to connect PC witch phone i use private Guid service = BluetoothService.SerialPort;

You can't send a file to the SerialPort (SPP) service; it is likely expecting AT command.  Use class ObexWebRequest to send files to the OPP service.

 Hello i have done what you propose and i have get a exeption when i have run bellow code :

 

ObexClientSession sessionFileSending = new ObexClientSession(service1, 65535);

sessionFileSending.Connect();  - here i have get a error

 

{"Unexpected OBEX response code: 0x80 (128)."} What is wrong the lenght of buffor 65635 or somethink else

0x80 is a seriously odd result code.  How did you create "service1"?  If you used BluetoothClient, what BluetoothService did you use?  ObexObjectPush?

TheBluetoothService  i use serialport and  ObexObjectPush bot was thi same exetion the pad to create the service1 is

 

Guid service = BluetoothService.SerialPort;

bc = new BluetoothClient();
BluetoothEndPoint serverEP = new BluetoothEndPoint((BluetoothAddress)adres, service, 2);
bc.Connect(serverEP);

NetworkStream service1;
if (bc.Connected)
{

service1 = bc.GetStream();
ObexClientSession sessionFileSending = new ObexClientSession(service1, 65535);
sessionFileSending.Connect();

}

 thanks for help gregor

Glad to hear you solved it!  Yup, using ports is almost always unnecessary in Bluetooth.
