I've been tinkering about Bluetooth USB adapter that Purchasing , I requested for the unit for R&D purposes with a planned kiosk project I have that needs to dispense digital music files onto bluetooth devices like mobile phones.
Several companies offer a wireless PAN USB adapter which is also called a wireless dongle. For example, you can purchase a USB Bluetooth adapter and connect it to a USB port on your PC. This makes the PC able to synchronize with other devices having Bluetooth connectivity.

802.15.1— This working group, Task Group 1, defines a wireless PAN standard based on Bluetooth v1.1 specifications, which uses frequency hopping spread spectrum (FHSS) and operates at up to 1 Mbps. The 802.15 group published 802.11.1 in June of 2002, and it is meant to serve as a resource for developers of Bluetooth devices.

Where the program connects directly to a Bluetooth RFCOMM service, and sends and receives the raw data for that connection. The BluetoothClient provides the Stream to read and write on -- there is no need to use virtual COM ports and the System.IO.Ports.SerialPort class.

Establishing OBEX client and connects to a server, and sends or GETs a file/object. The server side function can also be provided. See section OBEX http://obexdata.com/ .

Here we do not want the program to connect directly to those services, as we wouldn’t know what to do with the raw bytes, but instead want the OS to send audio to the headset, or form a network connection with an access-point or similar.

Where the program connects directly to a Bluetooth L2CAP service, and sends and receives the raw data for that connection.

//Here we define the Library and other thing like server/client Bluetooth.

Local Radio Information .

Local Bluetooth Radios are represented by the BluetoothRadio class, and an instance representing the primary radio can be accessed via the BluetoothRadio.PrimaryRadio static (Shared in Visual Basic) property. The class provides various information about the radio: the Bluetooth Address, the Class of Devices bits and the manufacturer, etc. The radio mode can be configured be setting the Mode property: it can be enabled, disabled, and put in discoverable mode. See the example below.

BluetoothRadio MyB_Radio = BluetoothRadio.PrimaryRadio;

RadioMode mode = MyB_Radio.Mode;

MyB_Radio.Mode = RadioMode.Discoverable;

Searching about the client around your device ..

publicvoid Search_client()

{

BluetoothClient devi_client = newBluetoothClient();

Device_s = devi_client.DiscoverDevices();

// store the device information in array "Device_s"

Devi_infobox.DisplayMember = "DeviceName";

//show devices name within listbox just showing the device name .

Devi_infobox.DataSource = Device_s;

}

When your bluetooth device begin receiving or sending files it using Obex protocol server/client and it will use thread to moving the data from pc to other mean that during the transferring from digital data to analog data ,

// open the Obex

Obex_listen = newObexListener();

Obex_listen.Start();

// Start threading

Begin_in = new System.Threading.Thread(new System.Threading.ThreadStart(Listener_to));

Begin_in.ApartmentState = System.Threading.ApartmentState.STA;

Begin_in.Start();
