Airplane mode Airplane mode shuts down the radio part of the module, causes the module to
log off from the GSM/GPRS network and disables all AT commands whose
execution requires a radio connection.
Airplane mode can be controlled by using the AT commands AT^SCFG and
AT+CALA:
• With AT^SCFG=MEopMode/Airplane/OnStart the module can be configured
to enter the Airplane mode each time when switched on or reset.
• The parameter AT^SCFG=MEopMode/Airplane can be used to switch back
and forth between Normal mode and Airplane mode any time during
operation.
• Setting an alarm time with AT+CALA followed by AT^SMSO wakes the
module up into Airplane mode at the scheduled time.
Charge-only mode Limited operation for battery powered applications. Enables charging while
module is detached from GSM network. Limited number of AT commands is
accessible. Charge-only mode applies when the charger is connected if the
module was powered down with AT^SMSO.
Charge mode
during normal
operation
Normal operation (SLEEP, IDLE, TALK, GPRS IDLE, GPRS DATA) and
charging running in parallel. Charge mode changes to Charge-only mode when
the module is powered down before charging has been completed.
See Table 6 for the various options proceeding from one mode to another.
