5.3 Bluetooth Services (Profiles)
5.3.1 Generic Serial (SPP) Service
The Bluetooth Generic Serial (Serial Port Profile or SPP) service is used by
your computer to connect to a Bluetooth-enabled device through a virtual
COM port. The serial connection can be used by legacy applications as it
emulates a simple RS232 serial cable link between two Bluetooth devices.
 Identify the COM Port Numbers:
The COM port numbers on your computer and the device will not change
from connection to connection. Each time the connection is established, the
same COM port numbers will be used.
1) Right-click the Generic Serial service icon to pop-up the context menu
2) Choose Properties from the context menu. The Bluetooth Configuration
panel (Local Services tab) will be displayed, followed by the Service
Properties dialog box.
3) Make a note of the COM port number
4) Click Ok
