Bluetooth Profiles
The device supports the following Bluetooth services:
•
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. PANU and NAP roles are 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.
•
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.
