Jim, IT TALKS!
Finally, it works with the Motorola as speaker for my NextUp Talker
However, now I cannot (yet) connect/syncronize my Nokia mobile with bluetooth, but at the worst, this can be done by cable.
I have learned a few things with all this. I discovered, that the installation of the stack is one thing, and then there is the installation of the dongle's own program! That I never did before; I thought the installation of the dongle was all. The installation of the dongle was in two parts. First part went fine, and it asked me to do a restart. After restarting, nothing more happened until I while looking for the program, happened to click a Bluetooth-icon in the Control Panel, and the installation continued with the configuration. Here I selected that I would use the Bluetooth for Filetransfer, syncronize with mobile phone and Headset.
Also, I have discovered that the driver for my dongle ( Conceptronic) actually is a widcomm. I noticed that the files were from 2003, so I let Windows search for a newer version. Guess what? The XP reinstalled the Windows stack! However, now I know the routine for updating the driver What gave me some trouble with the My Bluetooth Places, was that it showed no devices - nothing! However, a click on the View devices in range brought up a new window with the headset, and after a while and some attempts (right click on the icon), also appeared the option "Connect Headset". In my case, the Motorola gave a signal as if it recieved an incoming call, and had to be acknowledged by pressing the connect button on the Motorola.
I am very pleased, and in no small way thanks to you Jim!
