Wireless PAN Communication with Bluetooth
Bluetooth Radio
The on-board Bluetooth radio is enabled by default at startup and operates within the 2.4 GHz–2.48 GHz
band. Bluetooth transmissions hop between 79 separate frequencies 1,600 times every second, and with
a communication range of about 10 meters (class II).
Enabling the Bluetooth Radio
The Bluetooth radio must be enabled in order to connect to other devices. You’ll know that the radio is
not enabled if there is a yellow explanation point over the Bluetooth icon .
By default, the WLAN radio is enabled after each hard reset. Therefore, you must enable the Bluetooth
radio in the Radio Manager (see page 7-13). Tap Start > Settings > Connections tab > Radio Manager.
Select Bluetooth Only or Wi-Fi/Bluetooth, then tap OK to enable the radio.
BTExplorer
BTExplorer discovers Bluetooth devices in range and presents them in an easy-to-understand format
similar to Windows Explorer. BTExplorer visually separates trusted (paired) and untrusted remote devices
and identifies friendly names and services of remote devices. Custom icons indicate the device class
(type) as well as available services.
The services supported by the local device include
• File transfer
•OBEX
• OBEX object push
•FAX
•LAN access
• Dial-up networking
• Serial port communication
Pairing, security, and encryption settings can be configured for the local device. In addition to the
configuration options available, any of the supported services may be added to or removed from the local
device.
