![]() ![]() The Audio/Video Remote Control Profile (AVRCP) is often used in conjunction with A2DP for remote control on devices such as headphones, car audio systems, or stand-alone speaker units. For example, music can be streamed from a mobile phone to a wireless headset, hearing aid/ cochlear implant streamer, or car audio alternately from a laptop/desktop to a wireless headset also, voice can be streamed from a microphone device to a recorder on a PC. This profile defines how multimedia audio can be streamed from one device to another over a Bluetooth connection (it is also called Bluetooth Audio Streaming). This article summarizes the current definitions of profiles defined and adopted by the Bluetooth SIG and possible applications of each profile.Īdvanced Audio Distribution Profile (A2DP) This may include an outline of the required service record, if appropriate. To perform its task, each profile uses particular options and parameters at each layer of the stack. ![]() Specific parts of the Bluetooth protocol stack used by the profile. ![]() Devices such as mobile phones can expose additional profiles by installing appropriate apps.Īt a minimum, each profile specification contains information on the following topics: For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies.Ī host Operating System can expose a basic set of profiles (namely OBEX, HID and Audio Sink) and manufacturers can add additional profiles to its driver and stack to enhance what their Bluetooth device can do. The profiles provide standards that manufacturers follow to allow devices to use Bluetooth in the intended manner. The way a device uses Bluetooth depends on its profile capabilities. For example, there are Hands-Free Profile (HFP) 1.5 implementations using both Bluetooth 2.0 and Bluetooth 1.2 core specifications. While the profile may use certain features of the core specification, specific versions of profiles are rarely tied to specific versions of the core specification, making them independent of each other. It resides on top of the Bluetooth Core Specification and (optionally) additional protocols. A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices.
