Send AT+CFUN=0 to set the module to minimum functionality
1.
2. Drive MAIN_DTR low.
Execute AT+QSCLK=2 to enable sleep mode.
3.
4. Drive MAIN_DTR high.
5. Drive PON_TRIG low.
When the module is in sleep mode, perform the steps below in sequence to make the module exit sleep
mode.
1. Drive PON_TRIG high.
2. Drive MAIN_DTR low.
3. Execute AT+QSCLK=0 to disable sleep mode.
4. Send AT+CFUN=1 to set the module to full functionality
5. Drive MAIN_DTR high.
The figure illustrates the connection between the module and the host.
When the module has a URC to report, MAIN_RI will wake up the host. See Chapter 4.5.4 for details

about MAIN_RI behavior.
After the module is turned on, MAIN_DTR is internally pulled up by default.

AP_READY will detect the sleep state of the host (it can be configured to detect high or low voltage

level). See AT+QCFG="apready" in document [2] for details.
After setting the module to minimum functionality with AT+CFUN=0, you can test the lowest power consumption of the
6
module after the module enters sleep mode. If you need to keep the RF function on after the module enters sleep mode,
there is no need to send any AT+CFUN.
