Windows 11 Support for Bluetooth 5.3: Profiles, Protocols, and Compatibility

Windows 11, as of version 22H2, supports Bluetooth Core Specification version 5.3, encompassing a comprehensive range of profiles and protocols to facilitate diverse wireless functionalities. Core Specification Support:

• Host Controller Interface (HCI): Facilitates communication between the host system and the Bluetooth module.
• Attribute Protocol (ATT): Manages the exchange of data between devices.
• Generic Access Profile (GAP): Handles device discovery and connection management.
• Generic Attribute Profile (GATT): Defines the structure for data exchange.
• Logical Link Control and Adaptation Protocol (L2CAP): Supports data multiplexing and segmentation.
• Service Discovery Protocol (SDP): Enables devices to discover available services.
• Security Manager Protocol (SMP): Manages encryption and authentication.

GATT Profiles and Services:

• Device Information Service (DIS) v1.1: Provides device-related information.
• Generic Media Control Service (GMCS) v1.0: Controls media playback.
• Generic Telephone Bearer Service (GTBS) v1.0: Manages telephony services.
• HID over GATT Profile (HOGP) v1.0: Supports Human Interface Devices like keyboards and mice.
• Scan Parameters Profile Client (ScPP) v2.1: Optimizes device scanning processes.

Additional Bluetooth Profiles and Protocols:

• Advanced Audio Distribution Profile (A2DP) v1.3.2: Enables high-quality audio streaming.
• Audio/Video Remote Control Profile (AVRCP) v1.6.2: Allows remote control of media playback.
• Hands-Free Profile (HFP) v1.7.2: Facilitates hands-free calling.
• Human Interface Device (HID) v1.1.1: Supports devices like keyboards and mice.
• Object Push Profile (OPP) v1.1: Enables the exchange of objects like vCards.
• Personal Area Network Profile (PAN) v1.0: Supports networking capabilities over Bluetooth.
• Serial Port Profile (SPP) v1.2: Emulates serial port connections over Bluetooth.

For a comprehensive list of supported profiles and their versions, refer to Microsoft's official documentation. To verify the Bluetooth profiles supported by a specific version of Windows, you can consult the Bluetooth SIG website. Microsoft submits Bluetooth information for each Windows version to this site, allowing users to search for their Windows version and view the associated Bluetooth profiles. It's important to note that while Windows provides in-box support for these profiles, the actual functionality may also depend on the hardware capabilities and drivers provided by the device manufacturer. Therefore, ensuring that both the operating system and hardware are compatible is crucial for optimal Bluetooth performance.
