BlackBerry push notification properties allow BlackBerry users to install messaging client software on their devices.
| Property | Description |
|---|---|
| Enabled | Enables notifications to the device if the device is offline. This feature sends a push notification over an IP connection only long enough to complete the Send/Receive data exchange. BlackBerry Push notifications overcome issues with always-on connectivity and battery life consumption over wireless networks. Acceptable values: true (enabled) and false (disabled). If this setting is false, all other related settings are ignored. Default: true |
| Delivery threshold | The minimum amount of time the server waits to perform a push notification to the device since the previous push notification (in minutes). This controls the maximum number of push notifications sent in a given time period. For example, if three push notifications arrive 10 seconds apart, the server does not send three different push notifications to the device. Instead they are sent as a batch with no more than one push notification per X minutes (where X is the delivery threshold). Acceptable values: 0 – 65535. Default: 1 |
| Push listener port | The push listener port reported by the device on which it listens for notifications. This port is automatically assigned by the client. For example, if there is another application already listening on this port, a free port is searched for. Default: 5011 |
| Device PIN | Every Blackberry device has a unique permanent PIN. During initial connection and settings exchange, the device sends this information to the server. Unwired Server uses this PIN to address the device when sending notifications, by sending messages through the BES/MDS using an address such as: Device="Device PIN" + Port="Push Listener port". Default: 0 |
| Name | The BES server to which this device's notifications are sent. In cases where there are multiple BES servers in an organization, define all BES servers. |
