Mobile Channel Interfaces

Mobile channel interfaces provide a conduit for transporting data to and from remote devices. Two main channel interfaces provide messaging and replication.

• The messaging channel serves as the abstraction to all device-side notifications (BlackBerry Enterprise Service, Apple Push Notification Service, and others) so that when changes to back-end data occur, devices can be notified of changes relevant for their application and configuration.

  The messaging channel sends these types of notifications:

  • Change notifications - when Unwired Server detects changes in the back-end EIS, Unwired Server can send a notification to the device. By default, sending change notifications is disabled, but you can enable sending change notifications per synchronization group.

    To capture change notifications, you can register an onSynchronize callback. The synchronization context in the callback has a status you can retrieve.

  • When synchronizing, operation replay records are sent to the Unwired Server and the messaging channel sends a notification of replayFinished. The application must call another synchronize method to retrieve the result.
• The synchronization channel sends data to keep the Unwired Server and client synchronized. The synchronization is bi-directional.
