80 Getting Connected
6.4 Using Bluetooth
Bluetooth is a short-range wireless communications technology. Devices with Bluetooth
capabilities can exchange information over a distance of about 10 meters without requiring a
physical connection. You can even beam information to a device in a different room, as long
as it is within the Bluetooth signal coverage range.
Bluetooth can be used in the following ways:
•
Beam information, such as files, appointments, tasks, and contact cards, between
devices that have Bluetooth capabilities.
•
Synchronize information between your device and computer via Bluetooth.
•
Use a Bluetooth-enabled headset (or other Bluetooth-enabled hands-free device such
as a car kit) with your device for hands-free phone conversations.
•
Use a Bluetooth service. Once you connect to another device or computer using
Bluetooth, you can locate and use any of the services available on that device.
•
Create a connection between your device and a Bluetooth phone to use the phone as
a modem.
Note
Normally, you will need another phone as a modem only if your Pocket PC device has no
integrated phone capability.
Bluetooth modes
Bluetooth on your device operates in three different modes:
•
On. Bluetooth is turned on. Your device can detect other Bluetooth-enabled devices,
but not vice versa.
•
Off. Bluetooth is turned off. In this mode, you can neither send nor receive information
using Bluetooth. You might want to turn the radio off at times in order to conserve
battery power, or in situations where radio use is prohibited, such as onboard an
aircraft and in hospitals.
•
Discoverable. Bluetooth is turned on, and all other Bluetooth-enabled devices within a
range of 10 meters can detect your device.
Note
By default, Bluetooth is turned off. If you turn it on, then turn off your device, Bluetooth also turns
off. When you turn on your device again, Bluetooth automatically turns on.
