5.3.3 Minimum Functionality Mode and Flight Mode
Minimum functionality mode ceases a majority function of Module, in order to minimizing the power
consumption. This mode is set by the AT command which provides a choice of 3 different functionality
levels.
 AT+CFUN=0: Minimum functionality
 AT+CFUN=1: Full functionality (Default)
 AT+CFUN=4: Flight mode
If module has been set to minimum functionality mode, the RF SIM card function will be closed while the
serial port and USB are still available.
If module has been set to flight mode, the RF function will be closed, while the SIM card, the serial port and
USB are still available.
When module is in minimum functionality or flight mode, it can return to full functionality by the AT command
“AT+CFUN=1”.
