Before you can use ExtGPS in your Windows applications, you need to connect it using a Bluetooth serial port. Here are the instructions for Windows Vista, using the built-in Bluetooth stack. In Windows XP (or 2000), the process is similar, but depends on the Bluetooth stack your system is using.

First, you need to make sure you have Bluetooth enabled on your S60 phone, start ExtGPS and accept both security dialogs (for positioning and Bluetooth connectivity).

Now, open Bluetooth devices from Vista's Control Panel. Click Add to add your phone, if it's not already visible. Here's my S60 phone, already paired:



Then chances are you already paired the device before (as I did) so we need to make sure ExtGPS service is used. Open properties and check services tab: Serial port (SPP) 'Symarctic ExtGPS' should be checked.



After clicking Ok, COM Ports tab should show the port used:



(By default, Vista also creates incoming serial port (in case the device itself creates connection). As ExtGPS does not make connections by itself, you can delete that port.)

The GPS connection is now ready to be used. Depending on your GPS software, you might need to know that COMx number, though modern applications also show the port names.

Connecting GPS software to now configured serial port should start positioning on the S60 device.
