WAKEUP_OUT
S
IGNAL
The
WAKEUP_OUT
signal (PIN No. 1) is an output signal, active low. This signal is used for module to wake up the host. It is
designed as an OC gate, so it should be pulled up by the host and it is active-low. Figure 4-3 illustrates the reference connection
circuit of
WAKEUP_OUT
signal.

WAKEUP_OUT 1
DO
MP0:
Module wakes up
external AP, need to pull
up externally. Active low
This pin outputs a high-level voltage by
default. When a wake-up source arrives,
such as new SMS, call or network data
arrives, this pin outputs a low-level-voltage
pulse lasting for 1s.
Figure 4–5 Reference Connection Circuit of WAKEUP_OUT Signal
NOTE:
The resistors in Figure above is only the recommended value and they need to adjust according to the actual situation.
Do not directly connect this signal to the positive end of the power supply.
When there is a call/SMS received by the module, it will output the level shown as the figure below through WAKEUP_OUT pin to
wake the host.
