Class Watchdog2

java.lang.Object

com.cinterion.misc.Watchdog2

public class Watchdog2
extends Object

The Watchdog class provides a watchdog system timer.
When this watchdog triggers the module either switches off, reboots, or does nothing. This depends on the watchdog settings (see at^scfg=Userware/Watchdog). The watchdog is disabled when the module starts, the application has to enable it. It is never disabled implicitely. That means that the application has to disable the watchdog again when closing down (i.e. in its destroyApp method. This is especially necessary for OTAP to work correctly.
