I’ve received a number of emails about Windows Phone’s support for Bluetooth. Windows Phone utilizes Bluetooth 2.1 + EDR, the latest core Bluetooth specification, providing increased battery life and better security than previous versions. It also supports the following Bluetooth profiles:
Hands-Free Profile (HFP) 1.5. This is typically used for hands-free interfaces in automobiles.
Headset Profile (HSP). The most common BT profile, HSP provides support for wireless headsets.
Advanced Audio Distribution Profile (A2DP) 1.2. This provides high quality mono and stereo audio playback over Bluetooth.
A/V Remote Control Profile (AVRCP) 1.0. This allows a Bluetooth device to be used as a remote control. Windows Phone supports only the most basic remote control features (play, pause, stop, and so on).
Phone Book Access Profile (PBAP). This allows a BT-compatible device to exchange address book (contacts) data with another BT-compatible device. It is typically used with car kits so that contact names can appear on the in-car display.
Hope this helps.
