Allow Paired Devices to Connect
Paired devices share and exchange an internally generated Link
Key before each connection. The Link Key is derived from a
unique Bluetooth device address, a random number, and
user-defined password.
This feature allows only devices that you trust to connect to your
iPAQ Pocket PC.
To allow paired devices to connect:
1. From the Today screen, tap the Bluetooth icon.
2. Tap the Accessibility tab.
3. Select Allow other devices to connect, and then Paired
devices only.
4. Tap OK.

Enable Bluetooth Services

You can select to have certain services enabled:
Automatically when Bluetooth is activated
When you permit the connection
When a passkey or link key is correctly entered
You can use any of these security options when transferring files,
creating a serial port connection, exchanging business card
information, configuring dial-up networking, joining a personal
network, and connecting to a headset.
