How to Pair Smartphones Using Bluetooth Technology

Save

Bluetooth technology allows two devices, such as smartphones, computers, MP3 players or headsets, to quickly connect and begin sharing information within a range of about 10 meters. For security reasons, Bluetooth does not automatically connect whenever two Bluetooth devices are in range of each other. The two devices have to go through a connection process called pairing, where the device owners enter a passkey so that both parties agree to the connection.

  • Turn on Bluetooth technology on both your devices. Devices such as headsets and computers may always have Bluetooth on, but smartphones may have it off to conserve battery life. Turn it on by going into the "Bluetooth" menu, usually located in the "Settings" or "Connections" menus. There will be an option there to turn the technology on.

  • Place one of the devices into "pairing" or "discoverable" mode. If you are connecting a headset, follow the headset instructions to put it into pairing mode. If you are connecting two smartphones together, you only need to make one of them discoverable. There will be an option in the Bluetooth menu that will allow you to make the device discoverable.

  • Search for Bluetooth devices on the smartphone that you did not make discoverable. There will be an option in the "Bluetooth" menu to "Scan," "Search" or "Add." The smartphone will search for a few seconds and then list all of the nearby Bluetooth devices.

  • Select the device that you want to connect from the list of nearby Bluetooth devices.

  • Enter a passcode, or PIN, to complete the connection. If you are connecting to a headset, the passcode should be "0000." If it is not, you need to check the manual for that specific headset to get the passcode. If you are connecting two smartphones, or a smartphone and a computer, you can enter any passcode that you like, but you have to enter the same code on both devices. Once the passcode has been entered, the devices are paired.
