• 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.
15.3.3 Serial Interface Scenario (XSAP)This example describes the connection of two cellular engines. It is recommended that the instructions be fol-
lowed in the order that they are presented:
• Install two WinMux drivers on the PC and connect each ME to the physical port of a Multiplexer.
• Connect the PC application "ComBridge" to one virtual COM port of each Multiplexer. This establishes a com-
munication link between the two cellular engines. Bear in mind that AT commands can still be issued on both
cellular engines using the remaining serial channels.
• Select the "ComBridge" XSAP filter.
• Open the XSAP "Config Filter" menu and deactivate the "Startup - Send Initialization" and the "Shutdown -
Switch back to local SIM" tags. However, the appropriate device IDs need to be entered in the "Startup"
frame.
• Press the "ComBridge - st art" button to connect both MEs.
• Start the SAP client via AT command "AT^SRSA=2,2,3,0", if multiplexer channel 3 is used.
• Start the SAP server via AT command "AT^SRSA=1,1,3,0", if multiplexer channel 3 is used.
