Bluetooth

Bluetooth is a wireless technology that is designed to replace cables between devices, such as printers, keyboards, and mice.



Bluetooth wireless technology operates over a short distance. Bluetooth devices use radio transmission, which enables computers, mobile phones, printers, keyboards, mice, and other devices to communicate with each other without cables.

Bluetooth wireless technology has been included in Service Pack 2 for Windows XP. This support was not previously available directly from Microsoft.



Bluetooth is essentially a spread-spectrum frequency hopping radio transceiver, which means that it operates in a spread-spectrum mode and changes frequency for every data packet some 1,600 times per second.Bluetooth operates on 79 1 megahertz (MHz) bands between 2.4000 GHz and 2.4835 GHz.





Bluetooth defines several profiles, which identifies the services and features supported. Several available Bluetooth profiles are supported in SP2 including the following:

● Human Interface Device (HID):-

● Personal Area Networking (PAN)

● Dial-up Networking (DUN)

● Object Exchange (OBEX)

● Hard Copy Replacement

● Serial Port Profile (SPP)

Adding a device-pairing or bonding the two devices:-

When a Bluetooth device is added to your computer, address information is exchanged. Sometimes, access keys are also exchanged. It is known as pairing or bonding the two devices. When you add a device, one of the devices must be discoverable. Some devices let you turn discovery on and off. When We use Bluetooth to connect two computers, the computer that is added as a device must have discovery turned on. Turn on discovery by using the Options tab in Bluetooth Devices.



Steps to take on the computer:-



Start> Run>type bthprops.cpl>Ok



click Add in Bluetooth Settings>



In the Add Bluetooth Device Wizard>select the My device is set up and ready to be found check box>Next>Once you click Next, the search begins for any devices within range that are discoverable>Select the device>Next



After selecting the device, you have an option to enter a passkey for the device. This is a code used to control device access. In some cases the device will not require a passkey. Note that not all devices use or require a passkey for the pairing process,but HID don't require passkeys.

The passkey for the connection is valid for only 30 seconds.



Steps to take on the device:-

When the passkey has been verified, or the connection established without a passkey, the connection is complete. At this point, the device should be visible on the original computer.

In this case, you will see the computer name of the Windows XP computer that was added as a device.
