still receive paging message and SMS.
Several hardware and software conditions must be satisfied together in order to let MODULE enter into
sleep mode:
1. UART condition
2. USB condition
3. Software condition
Before designing, pay attention to how to realize sleeping/waking function and refer to Document [26]
for more details.
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 USIM card function will be
closed. In this case, the serial port and USB are still accessible, but RF function and USIM 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”.
5.4 Current Consumption
The current consumption is listed in the table below.
