This is a short "How To" for connecting a Nokia 3650/7650 to a desktop PC using a Bluetooth USB adapter. My adapter is a D-Link DBT-120. It comes with Widcomm software that is also often bundled with others adapters.

Installing the drivers

This step is quite straightforward and won’t be described here. Just remember to do the installation before connecting the adapter to your PC.

Once you have finished with it, you should have a small bluetooth icon added to your taskbar:

The Bluetooth configuration

Right click on the taskbar icon to start the bluetooth configuration wizard:

You can leave all the boxes checked and go to the next step. This second screen shows the version of the Widcom software you are installing (at the time of writing of this article, the latest version is 1.4.1 build 6). And, first important information, the name that will identify your computer for other bluetooth device. Patator is my computer name:

On the next screen, you have to selects the profile you want to use. Checking a box at this step does not mean that it will work since your phone may not support all them.

Some important profiles you should install:
  Serial Port: this is required if you want to use PC-Suite software or do some socket stuff between your mobile and your PC
  File Transfer: to use the right-click contextual menu to send file from your PC to your mobile
  PIM Item Transfer: is used by some Symbian applications to send files to your PC

Select the Configure button of the Bluetooth Serial Port profile. This will popup a window that will present the default COM port configuration the software has selected:

You can use the default setting or change it according to your needs. The only requirement is to remember the selected COM port (you will also be able to change this setting later).

Validate and go to the next step:

Select Skip. That’s it. You have finished configuring your adapter:

You still cannot establish a connection between your PC and your device. A second operation is needed: pairing the two devices together.
