5.4Charging

Please refer to [1] and [2] for general information about charging. Charging can be monitored by the running Java application. The JVM is active in Charge mode and in Charge-Only mode if autostart is activated. Only a limited number of AT commands are available when the module is in Charge-Only mode. A Java application must be able to handle the Charge-Only mode and reset the module to reinstate the normal mode. See [2] for information about the Charge-Only mode. The Charge-Only mode is indicated by URC “^SYSSTART CHARGE-ONLY MODE”.

Note: When a Java application is started in Charge-Only mode only AT Command APIs without CSD are available. The mode-indicating URC is created after issuing the very first AT com- mand on any opened channel. To read the URC it is necessary to register a listener (see [3]) on this AT command API instance before passing the first AT command.

5.5Airplane Mode

The main characteristic of this mode is that the RF is switched off and therefore only a limited set of AT commands is available. The mode can be entered or left using the appropriate AT^SCFG command. This AT command can also be used to configure the airplane mode as the standard startup mode, see [2]. The JVM is started when autostart is enabled. A Java appli- cation must be able to handle this mode. The airplane mode is indicated by URC “SYSSTART AIRPLANE MODE”. Since the radio is off all classes related to networking connections, e.g. SocketConnection, UDPDatagramConnection, SocketServerConnection, HTTPConnection, will throw an exception when accessed.

5.6Alarm

The ALARM can be set with the AT+CALA command. Please refer to the AT Command Set [1] and Hardware Interface Description [2] for more information. One can set an alarm, switch off the module with AT^SMSO, and have the module restart at the time set with AT+CALA. When the alarm triggers the module restarts in a limited functionality mode, the “airplane mode”. Only a limited number of AT commands are available in this mode, although the JVM is started when autostart is enabled. A Java application must be able to handle this mode and reset the module to reinstate the normal mode. The mode of a module started by an alarm is indicated by the

URC “^SYSSTART AIRPLANE MODE”.

Note: For detailed information which functionality is available in this mode see [1] and [2]. The mode indicating URC is created after issuing the very first AT command on any opened chan- nel.
