Please refer to 

 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 

 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 

on this AT command API instance before passing the first AT command.

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 

. The JVM is started when autostart is enabled. A Java ap-

plication must be able to handle this mode. The airplane mode is indicated by URC “SYS-
START AIRPLANE MODE”. Since the radio is off all classes related to networking connections, 
e.g. SocketConnection, UDPDatagramConnection, SocketServerConnection, HTTPConnec-
tion, will throw an exception when accessed.

The ALARM can be set with the AT+CALA command. Please refer to the AT Command Set 

and Hardware Interface Description 

 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 

 and 

. The 

mode indicating URC is created after issuing the very first AT command on any opened chan-
nel.
