accessible. The power consumption in this
mode is lower than
normal mode.
Flight mode
AT command “AT+CFUN=4” or pulling down the W_disable1# pin can
be used to set the Module to flight mode
without removing the
power supply. In this mode, the RF part of the Module will not work,
but the serial port and USB port are
still accessible. The power
consumption in this mode is lower than normal mode.
Power off
Module will go into power off mode by sending the AT command
“AT+CPOF” or pull down the FUL_CARD_POWER_OFF# pin, normally.
In this mode the power management unit shuts down the power
supply, and software is not active. The serial port and USB are is not
accessible.
5.3.2 Sleep mode
In sleep mode, the current consumption of Module will be reduced to a very low level, and Module
can still receive paging message and SMS.
Several hardware and software conditions must be satisfied in order to let Module enter into sleep
mode:
1. UART condition
2. USB condition
3. Software condition
Note: Before designing, pay attention to how to realize sleeping/waking function.
5.3.3 Minimum functionality mode and Flight mode
Minimum functionality mode ceases a majority function of Module, thus minimizing the power
consumption. This mode is set by the AT command which provides a choice of the 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 function and UIM card function
will be closed. In this case, the serial port and USB are still accessible, but RF function and UIM
card will be unavailable.
If Module has been set to flight mode, the RF function will be closed. In this case, the serial port
and USB are still accessible, but RF function will be unavailable.
When Module is in minimum functionality or flight mode, it can return to full functionality by the
AT command “AT+CFUN=1”.
