What is Bluetooth wireless technology?
Bluetooth technology is a personal area wireless networking standard. It uses low-power, short-range wireless technology designed for local areas voice and data communications. It operates in the 2.4 GHz ISM band, providing license-free operation in the United States, Europe and Japan.
What is pairing and why is it important?
Pairing is the process by which you establish a connection between two Bluetooth enabled devices, such as a headset and mobile phone. Because different Bluetooth products connect in different ways, you should read the Pairing Instructions for your new accessory. You may also need to consult the users' manual for your Bluetooth enabled phone.
Do I need to go through the pairing process every time I want to use a device with my Bluetooth phone?
No. To help conserve energy, usually the default Bluetooth setting on your phone is "Off." When you complete a pairing process, it only temporarily powers on. You can enable automatic connection between your compatible Bluetooth enabled device by changing the default Bluetooth setting on your phone to "On", and verifying that your Bluetooth device is set up to allow automatic access. When the phone is on, it enables Bluetooth power so you connect automatically when you turn on your Bluetooth device. You can also be paired with several Bluetooth enabled devices at the same time, such as a headset and stereo headphones.
What are Bluetooth Profiles and why are they important to me?
Profiles are what drive the communication between two different devices. The devices must have the same profile in order to communicate.
Like the drivers in computers, Profiles are software built into the device enabling communication. Bluetooth creates the connection used by Profiles to communicate with each other. If the devices do not have the same profile, they are unable to communicate.
Profiles are defined by use case. For example, there is a hands-free profile (HFP) which is found in most mobile phones and headsets to facilitate the hands-free experience. With the Advanced Audio Distribution Profile (A2DP) and Audio Video Remote Control Profile (AVRCP), you can stream music from your PC, home stereo or MP3 player with your Bluetooth phone.
Is Bluetooth compatible with every manufacturer's Bluetooth devices?
If the other device is qualified and supports the same Bluetooth profiles as the device, then the devices will be compatible.
Can I use a Bluetooth compatible PDA with my Bluetooth accessory?
For a PDA device you will need to contact the original manufacturer to get information on Bluetooth compatibility and directions to make use of certain Bluetooth profiles to communicate with another device.
Bluetooth is the standard for connecting devices together wirelessly. The PDA would need to support the same Bluetooth profile as the device in order to communicate.
How secure are Bluetooth products?
Bluetooth products are very secure. Majority of phones are only discoverable by another device when first turned on or when the user makes them discoverable. Even then, the phones only remain discoverable for usually 60 seconds, severely limiting the time for an intruder to gain access. Additionally, in most cases for Bluetooth, pairing is required before access is allowed for any service.
What is the latest Bluetooth standard? What standard do Girl Talk products adhere to?
