In these cases, it is impossible to connect certain A2DP headphones for high quality audio, while some vendors disable the A2DP functionality altogether to avoid devices rejecting A2DP sink.

Some Bluetooth stacks enforce the SCMS-T digital rights management (DRM) scheme. While designed for a one-way audio transfer - CSR has developed a way to transfer a mono stream back (and enable using headsets with microphones), and incorporated it into FastStream and aptX Low Latency codecs. For an extended list of codecs, see List of codecs §§ Bluetooth and Bluetooth lossless. It includes mandatory support for the low-complexity SBC codec (not to be confused with Bluetooth's voice-signal codecs such as CVSDM), and supports optionally MPEG-1 Part 3/ MPEG-2 Part 3 ( MP2 and MP3), MPEG-2 Part 7/ MPEG-4 Part 3 ( AAC and HE-AAC), and ATRAC, and is extensible to support manufacturer-defined codecs, such as aptX. These systems often also implement Headset (HSP) or Hands-Free (HFP) profiles for telephone calls, which may be used separately.Įach A2DP service, of possibly many, is designed to uni-directionally transfer an audio stream in up to 2 channel stereo, either to or from the Bluetooth host. 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). 37 Wireless Application Protocol Bearer (WAPB)Īdvanced Audio Distribution Profile (A2DP).35 Synchronisation Mark-up Language Profile (SyncML).32 Service Discovery Application Profile (SDAP).29 Phone Book Access Profile (PBAP, PBA).28 Personal Area Networking Profile (PAN).19 Human Interface Device Profile (HID).16 Hard Copy Cable Replacement Profile (HCRP).15 Generic Object Exchange Profile (GOEP).12 Generic Audio/Video Distribution Profile (GAVDP).3 Audio/Video Remote Control Profile (AVRCP).1 Advanced Audio Distribution Profile (A2DP).This article summarizes the current definitions of profiles defined and adopted by the Bluetooth SIG and possible applications of each profile. 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.For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies.Īt a minimum, each profile specification contains information on the following topics: 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.

If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.In order to use Bluetooth, a device must be compatible with the subset of Bluetooth profiles (often called services or functions) necessary to use the desired services. The BTHUSB service is using the BTHUSB.sys file that is located in the %WinDir%\System32\drivers folder. Close the command window and restart the computer. Copy the command below, paste it into the command window and press ENTER:ģ. Run the Command Prompt as an administrator.Ģ. Restore Default Startup Configuration for Bluetooth Radio USB Driverġ. Then Windows 10 will start up and notify the user that the BTHUSB service has failed to start due to the error.
