    SIM340 Hardware Design will return 0 which indicates that the protocol stack is closed. Then after 90s, SIM340 will power down automatically. However, during alarm mode, if the software protocol is started by AT+CFUN=1 command, the process of automatic power down will not be available. In alarm mode, driving the PWRKEY to a low level voltage for a period will cause SIM340 to be powered down (Please refer to the power down scenario).

    SIM340 Hardware Design following figure. Figure 11: Timing of restart system 3.5 Power saving There are two methods for the module to enter into low current consumption status. “AT+CFUN” is used to set module into minimum functionality mode and DTR hardware interface signal can be used to lead system to be in SLEEP mode (or slow clocking mode).

    SIM340 Hardware Design For detailed information about “AT+CFUN”, please refer to document [1]. 3.5.2 Sleep mode (slow clock mode) We can control SIM340 module to enter or exit the SLEEP mode in customer applications through DTR signal. When DTR is in high level and there is no on air and hardware interrupt (such as GPIO interrupt or data on serial port), SIM340 will enter SLEEP mode automatically.
