12.1.3 ATCommandListener Interface
The ATCommandListener interface implements callback functions for:
URCs
Changes of the serial interface signals RING, DCD and DSR
Opening and closing of data connections
The user must create an implementation class for ATCommandListener to receive AT
events. The ATEvent method of this class must contain the processing code for the different
AT-Events (URCs). The RINGChanged, DCDChanged, DSRChanged and CONNChanged
methods should contain the processing code for possible state changes.
12.1.3.1 ATEvents
An ATEvent or a URC is a report message sent from the module to the application. An
unsolicited result code is either delivered automatically when an event occurs or as a result
of a query the module previously received. However, a URC is not issued as a direct
response to an executed AT command. Some URCs must be activated with an AT
command.
Typical URCs may be information about incoming calls, a received SM, temperature
changes, the status of the battery, etc. A summary of URCs is listed in the AT Command Set
document [3].
12.1.3.2 Implementation
class ATListenerA implements ATCommandListener {
public void ATEvent(String Event) {
if (Event.indexOf("+CALA: Reminder 1") >= 0) {
/* take desired action after receiving the reminder */
} else if (Event.indexOf("+CALA: Reminder 2") >= 0) {
/* take desired action after receiving the reminder */
} else if (Event.indexOf("+CALA: Reminder 3") >= 0) {
/* take desired action after receiving the reminder */
}
/* No action taken for these events */
public void RINGChanged(boolean SignalState) {}
public void DCDChanged(boolean SignalState) {}
public void DSRChanged(boolean SignalState) {}
}
class ATListenerB implements ATCommandListener {
public void ATEvent(String Event) {
if (Event.indexOf("+SCKS: 0") >= 0) {
System.out.println("SIM Card is not inserted.");
/* perform other actions */
} else if (Event.indexOf("+SCKS: 1") >= 0) {
System.out.println("SIM Card is inserted.");
/* perform other actions */
}
}
public void RINGChanged(boolean SignalState) {
/* take some action when the RING signal changes if you want to */
}
public void DCDChanged(boolean SignalState) {
