SynCE - A project for connecting to devices running Microsoft Windows Mobile.
The SynCE project aims to provide libraries and tools to connect to and
synchronise with PDA's and other devices running Microsoft Windows Mobile, or
The main components include :-
Core library that provides various support services and functions.
Core library implementing the RAPI protocol, equivalent to rapi.dll on a Windows
OS. RAPI is used for most kinds of interaction with a WM device.
This library actually implements two versions of the protocol. RAPI 1 is used
for devices up to and including CE 5.0, with RAPI 2 coming into use from 5.1
Library implementing RRA (Remote Replication Agent), a protocol used for
synchronisation. This protocol is used for all data synchronisation until WM5,
at which point Airsync is used for the majority. RRA is still used for file
The dccm daemon negotiates the initial connection with a WM device, and may
provide keep-alive signals and client connections, depending on the device
version and flavour of dccm.
There have been a number of dccm 'flavours'. The original, also known as
synce-dccm, is now considered obsolete and should not be used. Vdccm is a
natural progression of dccm which is not greatly used anymore. Odccm is the
most common in use at the moment, and uses dbus to provide connections to both
legacy and modern devices. Hal-dccm is a new option that integrates the dccm
functionality into hal to provide a more platform consistent interface.
The following steps are required to get started with SynCE:
To use advanced network features (rndis) with a WM5 or later device, which is
recommended, you must use the usb-rndis-[lite|ng] driver from SynCE. For older
devices or to use serial with WM5, if synce-hal is not used you will require
the synce-serial package. You will of course also need a dccm daemon,
synce-hal or odccm is recommended.
If using odccm, this daemon must run as the root user. With synce-hal, dccm will
be started as required. Older dccm implementations must be run as your user.
See for example pls(1) and pcp(1).
