As many of you know I have become completely enfatuated with Bluetooth and the latest happenings in the wireless technology world lately. At first I was under the assumption that any Bluetooth device will work with any other Bluetooth device. This however, is unfortunately not true. Bluetooth devices use Profiles such as the Human Interface Device profile, which is the profile that mouses and keyboards use. So, my hopes of using a Bluetooth keyboard with my new Nokia 6620 are pretty much out the window now, unless someone writes an application that will allow this to happen. But, for those of you who are interested in compatability between Bluetooth devices, check out this PDF file I found on Logitech’s site about Bluetooth profiles.
