Bluetooth Power States
The Bluetooth radio is off by default.
• Suspend - When the device goes into suspend mode, the Bluetooth radio stays on.
• Airplane Mode - When the device is placed in Airplane Mode, the Bluetooth radio turns off. When
Airplane mode is disabled, the Bluetooth radio returns to the prior state. When in Airplane Mode, the
Bluetooth radio can be turned back on if desired.
Bluetooth Radio Power
Turn off the Bluetooth radio to save power or if entering an area with radio restrictions (for example, an
airplane). When the radio is off, other Bluetooth devices cannot see or connect to the device. Turn on the
Bluetooth radio to exchange information with other Bluetooth devices (within range). Communicate only
with Bluetooth radios in close proximity.
NOTE: To achieve the best battery life, turn off radios when not in use.
Table 13 Bluetooth Profiles
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.
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.
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.
