13.1.3ATCommandListener 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. This code shall leave the lis- tener context as soon as possible (i.e. running a new thread). While the callback method does not return it cannot be called again if changes occur.

The CONNChanged method indicates the start and the end of data connections. During a data connection it is possible to transfer data with the I/O stream methods (see Section 13.1.1.3). Some data services (i.e. FTP) transfer the data so quickly, that the CONNChanged start and close events are received even parallel to the response of the AT command which originated the data connection. The user’s application must realize, that the data connection had taken place and read the data with the I/O stream read methods afterwards.

13.1.3.1ATEvents

An ATEvent or a URC is a report message sent from the module to the application. An unso- licited 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 [1].
