The only software I'm using is Sony Ericsson Phone Suite.
I installed the Windows XP Pro Service Pack 2 Bluetooth Drivers and he now recognizes, by a USB Bluetooth dongle, my cell phone. Windows has a poor software. It gives you 2 choices only: send or receive and archive by bluetooth.
I've got a W810i and recently I bought a Bluetooth dongle to work on it. I've installed the drivers published by Sony Ericsson and the Windows XP SP2 "isscedrbta" driver from digiex.net .
Right now, Windows bluetooth driver recognizes my cell, so does SEPS. But there's simply no COM port showing ...
