Bluetooth is a proprietary open wireless protocol technology standard for exchanging data over short distances. In order to use Bluetooth technology, a device must be compatible with the subset of Bluetooth profiles necessary to use the preferred services.
A Bluetooth profile resides on top of the Bluetooth Core Specification and (optionally) additional protocols. Though the profile may use certain features of the core specification, specific versions of profiles are rarely tied to specific versions of the core specification. For example, there are HFP 1.5 implementations using both Bluetooth 2.0 and Bluetooth 1.2 core specifications.
Windows Phone supports Bluetooth 2.1 + EDR. With this enhanced version of Bluetooth, Windows Phone has a streamlined pairing procedure which diminishes user input and automates pairing with Bluetooth devices.
Windows Phone supports the following Bluetooth user profiles:
- Advanced Audio Distribution Profile (A2DP 1.3)
- Audio/Video Remote Control Profile (AVRCP 1.0)
- Hands Free Profile (HFP 1.5)
- Headset Profile (HSP 1.1)
- Phone Book Access Profile (PBAP 1.0)
Note: Certain Bluetooth devices may not fully toe the line to industry-standard Bluetooth protocols, so changes in the Windows Phone software may affect these devices. This is expected behavior and does not mean there’s an issue with your phone.
