The enhancement listed for this version 1.0 release is: <br /> <br /><i>• Adds support for Combination Key. Some Bluetooth devices require Combination Key support in orde </i>(sic) <i>to pair with the handheld device.</i><br /> <br />So, if you've been having Bluetooth problems with these devices, you know what to do.

What are Combination Keys?

They are needed for security when pairing up devices. For more details see here (http://www.businesssolutionsmag.com/Articles/2003_02/030226.htm).

Unlike 802.11b, Bluetooth uses two different keys for authentication and encryption. Authentication uses link keys, which can be either unit keys or combination keys. A unit key means the same key applies for each connection from a particular device. A combination key is different for each particular set of devices. The Bluetooth Special Interest Group recommends the use of combination keys for authentication, thus preventing the possibility of communication between two devices being overheard by a third device that has been paired with the originating device. To provide further security, it is recommended that this initial pairing take place in a private location.
