A connection between a cellular engine operating as a SAP client and an ME that supports Bluetooth and SIM

Access profile requires: 

a) System requirements 
• Windows 2000, Windows XP (or later) installed
• USB Bluetooth dongle. It is recommended to use the Fujitsu-Siemens product with the "PlugFree" Bluetooth

driver. This driver allows connections to Bluetooth profiles which are not yet specified by the SIG, e.g. SAP.

b) Installation procedure 
• After installing the USB Bluetooth dongle and the "PlugFree" driver software, the Bluetooth profiles are acces-

sible via their own virtual COM port.

• If the WinMux driver has been installed another three virtual channels (mapped to additional COM ports) are

available. The physical Multiplexer COM port is connected to the cellular engine.

• Start the Bluetooth connection using the driver provided by the USB Bluetooth dongle.
• Through "ComBridge", one virtual COM port supplied by "WinMux" is connected to the SAP COM port of

"PlugFree". This establishes an direct communication link between the cellular engine and the cellular phone.

However, AT commands can still be entered to the cellular engine via the remaining multiplexer channels.

• Select the "ComBridge" SAP filter.
• Press the "ComBridge-Start" button to connect both MEs.
• Start the SAP client using the AT command "AT^SRSA=2,2,3,1", if multiplexer channel 3 is used.
