ActiveSync OS Design Development (Windows Embedded CE 6.0)

1/6/2010

The ActiveSync functionality in Windows Embedded CE provides support for synchronizing data between a Windows-based desktop computer and Windows Embedded CE–based devices. Using time stamps and user preferences, the synchronization process tracks data changes on both computers, and then transfers the appropriate data so that each computer has the most recent versions. Outdated or unwanted data is discarded.

OS Design Information

The following table shows operating system design information for ActiveSync.

Concept Description

Dependencies

Desktop side Microsoft ActiveSync® version 3.5 or later is required.

Hardware considerations

A serial or USB cable connection is needed for the first synchronization. Subsequent synchronizations can also use IrDA or Ethernet connections.

Modules and Components

The following table shows the components and modules that implement ActiveSync.

Item Module Component

Base Synchronization

systemcpl, eventrst, rapisrv, repllog, rra_stm

None

File Synchronization

cefobj

None

Mail and PIM (POOM) synchronization

pegobj

None

Installer and Uninstaller

wceload, unload

None

ActiveSync Implementation Considerations

The following table shows the Sysgen variables that control ActiveSync.

Sysgen variable Description

SYSGEN_AS_BASE

Adds base synchronization components and the application installer and uninstaller.

SYSGEN_AS_FILE

Adds the file synchronization component.

SYSGEN_AS_MAIL

Adds synchronization for Inbox mail component.

SYSGEN_AS_PIM

Adds synchronization for Inbox contacts, tasks, and appointments.

By default, Repllog.exe is set up to be notified of any communications port events (NOTIFICATION_EVENT_RS232_DETECTED). If the driver sends this event, Repllog.exe starts automatically with the default parameters, as defined in the following section of datasync.db.

; @CESYSGEN IF DATASYNC_MODULES_REPLLOG
Record :
Field : 0001001f : "repllog.exe"
Field : 0002001f : "AppRunAtRs232Detect"
Field : 00030013 : 9
End
; @CESYSGEN ENDIF

If you do not need AutoNotify, remove this entry.
