The board of directors of the Bluetooth Special Interest Group (SIG) adopted Core Specification Version 2.1 + Enhanced Data Rate (EDR).

Through advances in security, simplified pairing and power consumption, the Bluetooth specification is designed to offer consumers a further improved Bluetooth experience, according to the Bluetooth SIG.

The Bluetooth SIG said silicon vendors such as Broadcom, CSR, Infineon and Texas Instruments will have Bluetooth v2.1 + EDR chips available and that the first products will follow by the end of the year.

Features of Bluetooth Core Version 2.1 + EDR include:

Improved Pairing
The improved pairing is touted as providing a consistent and intuitive pairing solution that includes finding devices, securing the link and authenticating the devices.

The benefits of this secure, simple pairing include fewer steps for the user, improved security and connection in a few seconds, according to the Bluetooth SIG.

The new pairing process is designed to enable consumers to start using their Bluetooth devices together.

For example, pairing a Bluetooth headset and mobile phone requires turning on the headset, selecting "Add Headset" from the phone menu and then watching the phone confirm it was found, connect with an encrypted link and pair the headset.

For pairing scenarios that require user interaction, eavesdropper protection makes a six digit passkey. Improved pairing also offers "Man in the Middle" Protection that is designed to eliminate the possibility for an undetected middle man intercepting information.

Near Field Communication (NFC) technology may also be used in the new pairing system whereby a user would hold two devices together at a very short range to start the quick pairing process.

Enhanced Power Optimization
Bluetooth Version 2.1 + EDR is designed to offer further optimized power consumption through a feature called Sniff Subrating, which increases current battery life by up to five times in many devices like mice, keyboards, watches, home sensor networks and medical devices, said the Bluetooth SIG.
