Not all work with all models.
I purchased an HP IPAQ in October of 2003, and I'm just now getting around to trying to install the Bluetooth that I got at the same time. I have everything on the PC green across the board, but when I try to go to The Bluetooth Manager on my PPC, I get "The Bluetooth Radio failed to turn ON due to insufficient driver memory available. You must perform a normal reset before you can turn ON The Bluetooth Radio." I've tried soft and hard resets, I've been to Ambicom's site and redownloaded the correct driver for my device, I've uninstalled and reinstalled Bluetooth several times and I still get the same message. Do I need a memory card, or am I just doing something wrong? Oh and also my PPC wants to use inbound COM port 8 and outbound COM port 5 and will not let me change it. (dunno if it's because I cannot access Bluetooth Manager or not)
