Profile | Description |
|---|---|
Service Discovery Protocol (SDP) | Handles the search for known and specific services as well as general services. |
Serial Port Profile (SPP) | Allows use of RFCOMM protocol to emulate serial cable connection between two Bluetooth peer devices. For example, connecting the device to a printer. |
Advanced Audio Distribution Profile (A2DP) | Allows the device to stream stereo-quality audio to a wireless headset or wireless stereo speakers. |
Audio/Video Remote Control Profile (AVRCP) | Allows the device to control A/V equipment to which a user has access. It may be used in concert with A2DP. |
Headset Profile (HSP) | Allows a hands-free device, such as a Bluetooth headset, to place and receive calls on the device. |
Hands-Free Profile (HFP) | Allows car hands-free kits to communicate with the device in the car. |
Out of Band (OOB) | Allows exchange of information used in the pairing process. Pairing is completed using the Bluetooth radio, but requires information from the OOB mechanism. Using OOB with NFC enables pairing when devices simply get close, rather than requiring a lengthy discovery process. |
Symbol Serial Interface (SSI) | Allows for communication with Bluetooth Imager. |
Generic Attribute Profile (GATT) | Provides profile discovery and description services for Bluetooth Low Energy protocol. It defines how attributes are grouped together into sets to form services. |
Generic Access Profile (GAP) | Use for device discovery and authentication. |
