Bluetooth is a wireless technology that allows computers, phones and other devices to talk to each other over short distances (typically about 10 meters). Bluetooth uses radio waves (in the 2.4 Gigahertz range), and is designed to be a secure and inexpensive way of connecting and exchanging information between devices without wires. You'll find Bluetooth in many of the newer mobile phones, handheld computers, laptops, printers, handheld organisers, as well as in all sorts of products. It uses a common protocol, so transmission of data (and voice) between two Bluetooth devices from different manufacturers should be straightforward. Uses of Bluetooth include: exchanging business cards, sending data over a modem, sending voice from a headset to a mobile phone, and real-time satellite navigation using GPS. This page provides some basic information on what Bluetooth has to offer, plus links to Bluetooth products.   Bluetooth products OK, so the promised Bluetooth fridge can't be bought at your local Comet store just yet, but here are a few examples of the Bluetooth products already available: Mobile Phone With a Bluetooth mobile phone such as the Nokia 6680 or the Sony Ericsson P910, you can do the following: Connect to your PC to transfer files and perform a backup. Exchange business cards, calendar entries and photos with other users Use a Bluetooth headset for hands-free calling Use the phone as a wireless modem from your Bluetooth-enabled laptop or PDA Connect to a Bluetooth GPS unit for satellite navigation Handheld PDA There's a wide range of Bluetooth-enabled Pocket PC or Palm OS handheld computers on the market. You can use Bluetooth for the following: Connect to your PC or laptop to transfer files. Share data with other users - including contacts, diary entries, documents and photos Connect to the Internet for surfing or email, via a Bluetooth-enabled modem or access point Connect to a Bluetooth GPS unit for satellite navigation This site has several pages on PDAs. We recommend that you check out the iPAQ range if you're looking for a powerful Windows Mobile Pocket PC with Bluetooth onboard. Phone Headset Hands-free calling from your mobile phone is possible with the aid of Bluetooth. OK, so you may end up looking like a Borg, but combining a Bluetooth mobile phone with a headset means you can use your phone without holding it to your ear, and without all those messy wires. Bluetooth headsets are available from a range of stores, such as the Carphone Warehouse and Add Ons World Printer / print adapter If you're looking to print without wires, there are a couple of options: Look for to a dedicated Bluetooth printer, such as the Samsung SSP-2040 , or the slightly older HP DeskJet 995C or HP DeskJet 450wbt Alternatively, you can buy a Bluetooth print adapter that lets you use Bluetooth with your existing printer. For instance, there's the BlueWalker Bluetooth Mobile Printer Adapter - With this printer adapter, you can enable wireless printing of data or photos from your Bluetooth-enabled desktop PC, Laptop, PDA and mobile phones. This printer adapter is designed to add more convenience and freedom to printing. It replaces the USB printer cable to enable wireless printing and has an additional USB port. It's easy-to-use and is able to activate wireless printing from up to 100 metres away. It's available for around £33 from amazon.co.uk. You'll find a selection of Bluetooth print adapters at online stores such as Amazon and Dabs.com. USB dongles and adapters Most PCs and laptops don't have built-in support for Bluetooth, but for around £15, you can add Bluetooth via a special USB Bluetooth adapter. We recommend the Belkin USB Bluetooth adapter available for around £12 from amazon.co.uk. - This lets you create cable-free connections between your USB desktop PC and devices using Bluetooth. The Adapter is compatible with Bluetooth v1.2-certified devices and enables you to connect wirelessly to up to seven other devices such as printers, PDAs, and mobile phones simultaneously. There's also a selection at Dabs.com. Modem / Access point Allows users to connect to the Internet using Bluetooth. The D-Link DBT-900AP Bluetooth Access Point is designed to extend LAN network services to Bluetooth-enabled devices such as laptop computers and PDAs. This Access Point provides a new solution for wireless connection of multiple users and devices on a Bluetooth network. For single use use, there's the Zoom Hayes Bluetooth 56K External Modem, which plugs into your phone line. Available from Misco and PC World GPS Navigation Connect your PDA, laptop or mobile phone via Bluetooth to a wire-free GPS receiver - these get a fix on your location from orbiting navigation satellites and overlays your position onto a map and/or route planner. For for on real-time mapping and route planning using Bluetooth, see our GPS page. If you have a Pocket PC, Windows Mobile or a Smartphone, consider TomTom Navigator 6 as your PC navigation software solution Many of the Bluetooth products mentioned above are available from UK supplier Dabs.com. Using Bluetooth Bluetooth presents a great way of exchanging data between devices. Here are the advantages: Cable-free, so less messy leads to worry about Interoperability - In most cases, you can use your portable Bluetooth device to connect with other existing Bluetooth points, without having to carry a data lead and CD of drivers around with you Here's an example of some of the things you can do with today's Bluetooth: Use your PDA and mobile to surf or check emails on the move Transfer files (such as mp3s and photos) to and from your mobile A wire-free headset for your mobile Backup your PDA or mobile to your PC Use a Bluetooth GPS device for satellite navigation on your PDA, laptop or mobile. Bluetooth Software: The good news is that if you have Bluetooth hardware in your mobile phone, PDA, GPS or headset, you probably won't need to worry about installing special Bluetooth drivers - the software is built-in and ready for use. If connecting to a PC, you'll need to install Bluetooth drivers (normally supplied on CD with your Bluetooth hardware, although you'll find that Windows XP Service Pack 2 comes with Bluetooth drivers that can be used with some plug-and-play Bluetooth hardware (such as the Belkin USB dongle), so there's less messing around. Windows XP SP2's Bluetooth driver with a Belkin Frequently-asked questions: Why Bluetooth? Where did the term Bluetooth originate? Bluetooth was originally developed by mobile phone company Ericsson in 1994. Looking for a unique name for the technology, they settled on "Bluetooth" after a tenth century viking king called Harald "Bluetooth" Blatand. During his reign, he united Denmark and Norway, and was well known for his ability to help people communicate. Presumably, Ericsson's hope was that Bluetooth technology could do the same. Passcode What is my passcode? In order two 'pair' one Bluetooth device to another, a passcode has to be exchanged between the two devices. When you first connect, one machine will ask you to enter a passcode... enter any 4 digit number. The other device will then ask you for a passcode. Enter the same 4 digit number. It doesn't matter what the passcode is, as long as you enter the same number at both ends. Phone to PC? If you have a Bluetooth-enabled mobile phone, then you can use Bluetooth to beam your photos and other objects from your phone to a PC or laptop. You'll need to have Bluetooth on your PC (if it doesn't already have Bluetooth, see our other FAQ on this). With Bluetooth switched on on both the phone and PC, you need to 'pair' the two machines, and then you can use the software on the phone and PC to transfer files. Bluetooth-enabled phones include the Series 60 range of smartphones (such as the Nokia 6680), as well as Windows Mobile phones such as the o2 XDA Orbit Bluetooth on a PC If you want to add Bluetooth functionality to your PC or laptop, the best bet is to buy yourself a Bluetooth USB adapter that plugs into a spare USB port on your PC. We recommend the Belkin USB Bluetooth adapter available for around £12. This comes with the software needed to get a Windows 98 SE, Me, 2000, XP or Vista PC enabled with Bluetooth. Wi-fi? Is Bluetooth the same as Wi-fi? Bluetooth is not to be mistaken for wi-fi (wireless networking) - Bluetooth runs at a lower speed and power than wi-fi. Are WiFi and Bluetooth compatible? Bluetooth and WiFi are both radio technologies, but they differ in the frequencies and protocols that they use. They don't interfere with each other, but the two don't talk to each other either - in other words you can't get a device with Bluetooth to communicate to a device that only supports WiFi. Security There seem to be a number of security concerns about Bluetooth - should I be worried? There have been some security concerns, and you should make your own judgment on the convenience of Bluetooth verses the risk of having someone gaining access. Here's a summary of the scare types: Bluejacking - A craze in 2004, where people with Bluetooth mobiles scan for other users with Bluetooth enabled, and beam a Contact Card containing a greeting. This is usually harmless, and exploits a common feature of Bluetooth - the ability to beam business cards. You still have to accept the card. Calls being overheard - some Bluetooth handsets and headsets use an obvious passcode, such as 0000, meaning that some hackers have apparently been able to hi-jack connections (to access the microphone or to eavesdrop on a call) Clever thieves have been known to use Bluetooth and Wi-fi checkers to see if a car's boot or glovebox contains a Bluetooth device There's some clever software out there that can make use of vulnerabilities in a small number of Bluetooth phones, to establish a data connection. For most people, the likelihood of something nasty happening is pretty low, but if you want to play it safe, here are a few tips: 1) when not using Bluetooth, turn it off. 2) Set your Bluetooth mode so that it isn't discoverable. 3) Be careful of devices that may have a guessable passcode. 4) Be careful when setting a device to "trusted" or "authorised", as that device can then access all of your devices services, features, and potentially - data. For more information on Bluetooth security, take a look at The Bunker's feature or Virus.org's Bluetooth FAQ Compatibility Are all Bluetooth devices compatible with each other? Thanks to Frank Kubanek for contributing the following note: Bluetooth is equivalent to a 'wireless USB cable' with the security and limitations. To prevent disappointment and angry buyers, note that Bluetooth is a new technology coming to market, and although the standards are established, implementation depends on the vendor. The hardware will work as advertised, but it's important to note that the drivers for the devices are not necessarily there to allow all Bluetooth devices to connect to all other Bluetooth devices. The standard exists and the hardware exists, hopefully the vendors of Bluetooth devices don't destroy the market by promises of compatibility and a failure to deliver. Got a question on Bluetooth?

We're using a Windows Mobile iPAQ as an example. We have instructions for the Loox here. Turn on the Bluetooth phone and enable Bluetooth - how you do this depends on the make and model. Some examples: On the SonyEricsson P900, go to Control panel, 'Connections' tab, 'Bluetooth', 'Settings' tab. Set 'Operation mode:' to "Discoverable" On the Nokia 6600/Nokia 3560, go to 'Connect', 'Bluetooth', On the first tab, press in the joystick button to set Bluetooth to "On" On the SonyEricsson T68, go to 'Connect', 'Bluetooth' and set 'Operation mode' to "On" On the Nokia 6310i, use the menu to navigate to 'Bluetooth' and select "On" Turn on the Pocket PC, and enable Bluetooth (On an IPAQ, this is Settings > Connections > Bluetooth > Turn on) You then need to search for the Bluetooth mobile from the Pocket PC. From the Pocket PC Bluetooth Manager (On an IPAQ, this is Settings > Connections > Bluetooth > Bluetooth Manager), select "New" to start the wizard. Select "Connect to Internet via phone" and press "Next" Assuming your phone isn't listed in "Phone selection", specify "Unknown" and press "Next" twice On the next screen, set the pull-down at the bottom of the screen to "All devices" and wait while the PDA scans for devices in range Select your phone from the list of detected Bluetooth devices You'll be prompted for a Passkey. Enter "1234" and press "Next". Look at the phone - you should be being prompted to enter a passkey - enter "1234" and proceed. The PDA will then discover what services are available. Tick the "use as default connection", and then tap on "New connection". Enter details of the dialup account you want to use (more here). Finish to exit the Wizard Now, go to the web browser, and try to visit a website - You'll be asked for your dialup username and password. Once you've entered this, the PDA should start dialling, and make the connection. You should now be ready to connect to the Internet. For more on connecting, see the following instructions: Connecting Pocket PC for Web and email Connecting Pocket PC for WAP access Searching and pairing on a SonyEricsson P800 / P900 Go to Control panel, 'Connections' tab, and select 'Bluetooth' From the 'Settings' tab, set 'Operation mode:' to "Discoverable" Search for devices by pressing 'Add' Select the device you want to pair to. When prompted, enter the passcode. If the device you're pairing to already has a passkey, you'll need to use that key, otherwise, enter a key (such as a 4 digit number) Enter this number on the device you want to pair to To send a file, select the object to send, and from the menu, select 'Send As > Bluetooth' Further information: P800 information, P900 information, P900/P910 Internet Searching and pairing on a Series 60 phone This section helps with using Bluetooth on a Series 60 phone such as a Nokia 6600, Nokia 7650 or the Nokia 3650 Go to 'Connect' and select 'Bluetooth' From the first tab, select 'Bluetooth', and by pressing in the joystick, set Bluetooth to "on" Move to the second tab, press "Options" and select "New paired device" Select the device you want to pair with. You'll be promoted to enter a passcode. If the device you're connecting to already has a passcode, then you'll be prompted to add this, otherwise you'll need to create a passcode. Use a number like 1234 (you only need this once to get a pairing, so you don't need to remember it You will be prompted to enter the passcode on the device you want to pair to (unless it already has a passcode). Enter the code that matches the one you entered on the phone, and "ok" it. To allow the phone to always connect without prompting and pairing, you can set the device as "authorised". Do this by selecting the device, and from the options menu, select "Set as authorised".
