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.
Object Push Profile (OPP)
Allows the device to push and pull objects to and from a push server.
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.
Personal Area Network (PAN)
Allows the use of Bluetooth Network Encapsulation Protocol to provide L3 networking capabilities over a Bluetooth link. Only PANU role is supported.
Human Interface Device Profile (HID)
Allows Bluetooth keyboards, pointing devices, gaming devices and remote monitoring devices to connect to the device.
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.
Phone Book Access Profile (PBAP)
Allows exchange of Phone Book Objects between a car kit and a mobile device to allow the car kit to display the name of the incoming caller; allow the car kit to download the phone book so you can initiate a call from the car display.
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.
Dial Up Networking (DUN)
Provides a standard to access the Internet and other dial-up services over Bluetooth.
Generic Access Profile (GAP)
Use for device discovery and authentication.
OBject EXchange (OBEX)
Facilitates the exchange of binary objects between devices.
