Q1 :  What is Bluetooth?
A1 : Bluetooth wireless technology revolutionizes the personal connectivity market by providing freedom from wired connections - enabling links between mobile computers, mobile phones, portable handheld devices, and connectivity to the Internet. Interface, synchronize, exchange. All of the above, and more. Bluetooth technology redefines the very way we experience connectivity.

Q2 : Where does Bluetooth work?
A2 : Everywhere. Hardware that complies with the Bluetooth wireless specification ensures communication compatibility worldwide. As a low cost, low power solution with industry wide support, Bluetooth wireless technology allows you to bring connectivity with you. You define the boundaries of your productivity - in whatever place your business may take you.

Q3 : Why does Bluetooth work?
A3 : Establishing a standard means integrating well-tested technology with the power efficiency and low-cost of a compliant radio system (about the Specification). Establishing a standard also means a group of industry leading promoter companies who drive the specification forward (about the Bluetooth SIG). Bluetooth technology works because it has been developed as a cross industry solution that marries a vision of engineering innovation with an understanding of business and consumer expectations.

Q4 : Who's making it work?
A4 : Bluetooth wireless technology is supported by product and application development in a wide range of market segments, including software developers, silicon vendors, peripheral and camera manufacturers, mobile PC manufacturers and handheld device developers, consumer electronics manufacturers, car manufacturers, and test and measurement equipment manufacturers.

Q5 : What is Pairing?
A5 : Normally, for security reasons, two Bluetooth devices always need to be initially paired before they can exchange data. The term, pairing (or bonding as it is sometimes referred to), normally means that two devices are exchanging protected passkeys. Once paired, all information sent over the Bluetooth link is encrypted and will only be able to reach devices that are authorized to do so by the pairing process. At certain instances it makes sense to override pairing procedure. E.g. When exchanging business cards between two mobile phones, it may be too cumbersome for pairing with password. Usually there is a setting in the device where you can set a lower level of security for such instances. It should also be noted that on some devices you will always need to make the device discoverable by setting the "discoverable menu" or preparing to accept business card.

Q6 : Why my mobile phone cannot print to a printer with Bluetooth enable?
A6 : For devices to work together, it is important that each device that communicates share the same profile. Your mobile phone may not support "Basic Printing Profile" so cannot print to a printer.

Q7 : Why I cannot use my bluetooth headset with a Bluetooth mobile phone?
A7 : For devices to communicate with Bluetooth wireless technology, you will need to make sure that both devices have the Bluetooth functionality turned on. Even though the basic design of Bluetooth provides for an extremely low power consumption, the functionality can be switched off to save even more power, or to disable radio functionality in special situations such as during airplane take off. In most devices, the Bluetooth functionality is switched on by software. This is typically done from a menu choice, "Turn Bluetooth radio on".

Q8 : Why my mobile phone cannot be paired with my headset?
A8 : Your mobile phone or headset may not be in "discoverable mode". Make the unit you are trying to find and pair with visible/discoverable by either turning this on from the appropriate menu, or by a sequence of keystrokes usually on devices with limited user interface. You may have also entered a wrong pass code to pairing.

Q9 : How to pair my Bluetooth devices?
A9 : Typically, pairing is done in two ways depending on the type of devices. For example, pairing a headset and a mobile phone necessitates setting one of the devices into pairable mode and activating the pairing from the other device. For most devices, there is no need to perform additional operations to establish a connection once paired.

Q10 : What is Master/Slave and Multipoint?
A10 : These are technical terms that most users do not need to worry about. However, for each small personal network (piconet), one device always acts as master and the other units are slaves. All devices independent of capability can take both master and slave roles. If you have many devices connected in a personal network (more than one slave to a master), it is called multipoint. I.e. A computer could simultaneously connect and transmit data to both PDA, camera, and a mobile phone at the very same time.
