When you try to use a Bluetooth-connected device to connect to a Microsoft Windows XP Service Pack 2-based computer or Microsoft Windows XP Tablet PC Edition 2005-based computer, the device may not be able to make the connection.
This problem may occur if the discovery option is turned off on a computer that is running on Windows XP Service Pack 2 or Windows XP Tablet PC Edition 2005 that has Bluetooth support. By default, the discovery option is turned off so that the Windows XP-based computer cannot be discovered by a Bluetooth-connected device without your knowledge or consent.
To work around this problem, you must turn on the discovery option in Bluetooth. To do this, follow these steps:
Important Turn on discovery only when you want a Bluetooth device to find your computer. After the device has been added or bonded with your computer, discovery is no longer required. You can turn it off to help protect your privacy.
