6.3.3 Deep Sleep
This command is used to enable the GS node’s power-saving Deep Sleep processor mode.
Command Syntax
AT+PSDPSLEEP
Usage
When enabled, the GS node will enter the power-saving Deep Sleep mode when no actions
are pending. In Deep Sleep mode, the processor clock is turned off, and GS node power
consumption is reduced.
The processor can be awakened by sending data on the serial port from the host. However,
several milliseconds are required to stabilize the clock oscillator when the system awakens
from Deep Sleep. Since the clock oscillator must stabilize before data can be read, the initial
data will not be received; “dummy” (discardable) characters or commands should be sent
until an indication is received from the application.
Response
These commands do not return any response code to the serial interface. The IP2WiFi
application sends the message “Out of Deep Sleep” along with the standard response once
it comes out from deep sleep.
Parameter Description
A similar command can be used to enable the deep sleep with a timeout and alarm.

NOTE:
1.) Other components external to the GS node may continue to dissipate power
during this time, unless measures are taken to ensure that they are also off or
disabled.
2.) Only Station Mode supports DeepSleep and Standby (AT+PSDSLEEP and
AT+PSSTBY).
