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.

Enabling Bluetooth

To enable Bluetooth:

1. Swipe down from the Status bar to open the Quick Access panel.

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.

Human Interface Device Profile

(HID)

Allows Bluetooth keyboards, pointing devices, gaming devices and

remote monitoring devices to connect to the device.

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.

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.

OBject EXchange (OBEX) Facilitates the exchange of binary objects between devices.
