> 15.3.2 | Bluetooth scenario (SAP)

> 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 accessible 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 a direct communication link between the cellular engine and the cellular phone. However, take into account that AT commands can still be entered on the remaining multiplexer channels of the ME.

> • | 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.
