Bluetooth is a sort of wireless communication, initially developed in the 1990s by Ericsson, a Swedish telecommunications company. The name “Bluetooth” is derived from the 10th-century Scandinavian king Harald Bluetooth, symbolizing the technology’s intent to unite varying communication protocols like King Harald united Denmark and Norway.
Bluetooth operates in the 2.4 GHz ISM (Industrial, Scientific, and Medical) band, utilizing a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec.
The frequency hopping helps to minimize the effects of interference from other sources of radio frequency energy.
Here are solutions to some common problems with Bluetooth enabled devices:
1. When your Computer doesn’t recognize your Bluetooth enabled device.

There are several things to try:
* Make sure the device and your computer are the correct distance apart. The device information should include the correct distance.
* The device might be too busy or have too many connections (for example, other devices might be connected to a Bluetooth enabled printer). Wait until the device is less busy, and then try again. Or, to reduce the number of connections, set the other devices so that they are not discoverable. If you’re not sure how to turn off discoverability, check the information that came with the device or go to the manufacturer’s website.
* Make sure that your computer is trying to connect to the correct device. For example, you might have two Bluetooth enabled printers connected to your computer: one in your office and one in a co-worker’s office. Make sure the name and serial number shown in the Add Bluetooth Device Wizard match the name and serial number of the device by right-clicking the device icon in the wizard.
* Have you exchanged passkeys with the device? Some devices require a passkey before they can be listed in Bluetooth Devices in Control Panel.
* Maybe you typed an incorrect passkey, or the time limit expired for typing the passkey.
* Make sure Windows is configured to accept incoming Bluetooth connections. To do so, if you have Bluetooth wireless technology installed on your computer, you can check Control Panel for Bluetooth enabled devices.
Here’s how:
i. Click the Start button
ii. Click Control Panel,
iii. Click Hardware and Sound, and then click Bluetooth Devices.
iv. Click the Options tab, select the Allow Bluetooth devices to connect to this computer check box, and then click OK.
* If the device is close to other devices that use radio frequencies (such as microwave ovens, cordless phones, remote controls for electronics or lighting, or 802.11 wireless networks), those devices might be creating interference. Try moving the device that isn’t working farther away from the other devices.
4. The connection to your device is slow or intermittent.
There are several things to try:
* The device and your computer could be at the edge of their range or too close to each other. Move the device closer to your computer or farther away. The device information should tell you the correct distance.
* The device might be too busy or have too many connections. For example, other devices might be connecting to a Bluetooth enabled printer, preventing this connection. Wait until the device is less busy, and then try again. Or, to reduce the number of connections, set the other devices so that they are not discoverable. If you’re not sure how to turn off discoverability, check the information that came with the device or go to the manufacturer’s website.
* If the device is close to other devices that use radio frequencies (such as microwave ovens, cordless phones, remote controls for electronics or lighting, or 802.11 wireless networks), those devices might be creating interference. Try moving the device that isn’t working farther away from the other devices.
* Security might have been reset on either device. This is especially common with keyboards and mice. Other devices can have similar problems and might need to be reinstalled.
