The diagnostic base system can access the VAS 5054A via Bluetooth. After a connection via Bluetooth to the VAS 5054A has been set up, the Bluetooth software provides a virtual serial COM port (Bluetooth Serial Port Profile). The Diagnostic Base System uses this COM port to communicate with the VAS 5054A. You need to specify this port when you install the diagnostic application.
