 Sending data to AG35-Quecopen through USB will wake up the module.
 When AG35-Quecopen has URC to report, the module will send remote wake-up signals via USB
bus so as to wake up the host.
3.5.1.2. USB Application without USB Remote Wakeup Function
If the host supports USB suspend/resume, but does not support remote wake-up function, it needs to be
woken up via the module’s GPIO.
There are three preconditions to let the module enter into the sleep mode.
 Use sleep & wakeup API to enable the sleep mode.
 Ensure the level of pins that configured as wake-up interrupt in Table 5 are under non-wakeup
status.
 The host’s USB bus, which is connected with the module’s USB interface, enters into suspended
state.
The following figure shows the connection between the module and the host.

 Sending data to AG35-Quecopen through USB will wake up the module.
 When AG35-Quecopen has URC to report, the module’s GPIO signal can be used to wake up the
host.
3.5.1.3. USB Application without USB Suspend Function
If the host does not support USB suspend function, USB_VBUS should be connected with an external
control circuit to let the module enter into sleep mode.
 Use sleep & wakeup API to enable the sleep mode.
 Ensure the level of pins that configured as wake-up interrupt in Table 5 are under non-wakeup
