Yes this is possible. SSP BT / BT Classic creates a COM port and this acts just like a serial cable. You need to pair the PC with the BT module used in the droipController to create the COM port. Once you have this select the port in the dropController Windows app.
See http://www.dropcontroller.com/connecting-dropcontrollerpc-via-bluetooth/. This is for a BlueSoleil Bluetooth dongle but the process is similar for other dongles.
