Figure 4: USB Application with Suspend Function
When the processor’s USB bus returns to resume state, the module will be woken up.
3.5.1.3. USB Application without Suspend Function
If application processor communicates with module via USB interface, and processor does not support
USB suspend function, you should disconnect USB_VBUS with additional control circuit to let the module
enter into sleep mode.
Execute AT command AT+QCFG="uart/power",0,0 to set UART into auto on/off mode.
Execute AT command AT+QSCLK=1 to enable the sleep mode.
Disconnect USB_VBUS.
Supply power to USB_VBUS will wake up the module.
