The Vayusphere XMPP Client for BlackBerry offers the following Preference settings to fine tune the application to your liking. The Preferences menu is available from all screens inside the application.

Preference item changes take effect immediately.

(Note that additional settings may be available in the Edit Account menus when you configure your username and password. Those settings are specific to each account you have configured while Preference settings are global)

Preference Items and their meaning:

Auto Login on Launch: If username and password is set, the application will autologin to the last used account when you enter the application as well as when you reboot your device. It is recommended that you leave this Unchecked till the application has been properly configured.

Show Online Users Only: If checked, hide users in the contact list that are not online. This helps you maximize the number of users visible on the small screen. When in the application, you can also use the short key O to toggle between online and all user views.

Mark Idle on Inactivity for X minutes: After you have been idle on the device for this many minutes, the application will set your status to Idle. You can set other status messages when in the application by using the S short key. You can use the X short key to mark yourself Busy

Alerts and Notifications

The application is able to alert you using one or more of the following: LED Blinking, Sound or Vibrate. The Vayusphere application will use the Blue color in the LED if your device supports a multi color LED. You can control when you wish to be alerted:

Alert When Connected: Application will Alert you when it connects to the server. (On by Default)
Alert When Disconnected: Application will Alert you when the connection to the server is interrupted by the server. (Off by default)
Alert on Network Error: Application will alert you if the connection to the server is lost because of a connectivity issue. (Off by default)
Alert on incoming message: Application will alert you when a new message arrives. (On by default)
Alert on presence change: Application will alert you when the presence/status of any of your contacts changes. (Off by default)

Alert Method:

Blink LED on new message: On by default. LED blinks when new message arrives. Note that LED blinking is available only for new messages.
Vibrate on Alert: Device will vibrate if this is selected, and a selected Alert condition occurs.
Play sound on Alert: Device will play a sound when this is selected, and a selected Alert condition occurs. You can control the volume of the sound using the percentage gauge (Alert Volume)

Display

Versions later than 3.6.143 offer a selection of:

Font Family
Font Size

Changing Font options will change the font used by the application throughout.

Show Timestamp: If selected, a timestamp is shown ahead of each message.

Max Message Length (Bytes): Application will only display the first X bytes of each message. The default setting at 4000 bytes is larger than what other clients can send.

Multi User Chat or Group Chat Related settings:

The Vayusphere application supports persistent group chat. When you join such a chat room, the server can often send you a history of messages previously exchanged in that room before you join. Some, but not all servers, offer the client some flexibility in the amount of history that can be sent to the client. They may implement one or more of these options. Other servers will ignore these settings, and send a fixed amount of history configured on the server side.

Max MUC History (Count): Request last X messages.
Max MUC History Bytes: Request last X bytes worth of messages.
Max MUC History Seconds: Request messages exchanged in last X seconds.

Contact List Display:

Conversation Timeout (minutes): The Vayusphere application supports a virtual group in the contact list where active conversations are shown. This helps in navigating quickly to active conversations. After no messages have been exchanged in a chat session with a remote user in X minutes, the conversation will no longer be considered Active and it will be removed from the Active conversation listing. A new message from either party will restore the conversation to active status automatically. You can also manually mark the End of conversation using a corresponding menu item.

Keepalive (Seconds): The Vayusphere application connects to the remote XMPP server over a TCP socket connection. Often, servers are configured to terminate a session if no traffic is exchanged in the last X seconds. There may be firewalls and proxy servers in the path that also terminate what they consider idle sessions. Therefore, the application sends out a keepalive message consisting of a single byte every X seconds. The default setting of 240 seconds is usually sufficient as most servers expect some activity every 300 seconds. It is helpful to note that any traffic, including presence status changes of anyone in your contact list will reset this timer, so the keep alive is just a safeguard mechanism. If your environment enforces a more aggressive timeout you can decrease this value. Note that decreasing the value will cause more frequent network traffic with corresponding effect on battery life and bandwidth usage. You should only change this value if you see frequent disconnects when idle.
(This setting is scheduled to be removed from the Preference items and moved to Account settings in a future release. If you should not find this setting in Preferences, please look in the Edit Account setting)
