Note/Tip:
1.) Other components external to the TELIT 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).
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 no
t 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 S2W
application sends the message “Out of Deep Sleep” along with the standard response
once it comes out from deep sleep.
A similar command can be used to enable the deep sleep with a timeout and alarm:
AT+PSDPSLEEP=[<timeout>,<ALARM1 POL>,<ALARM2 POL>]<CR>
Parameter Description
Table 75: Deep Sleep Parameters.
Parameter
Optional/Mandatory
Value
Description
Timeout
Optional
Integer by 32bit value
Node goes to deep sleep state for the
configured time in milliseconds and upon
time out exits the node from deep sleep
state. Max time out value is 32 bits.
ALARM1 POL
Not Supported
0 (high-to-low)
1 (low-to-high)
This is the polarity of the transition at pin
RTC_IO_1 of the TELIT node will trigger an
alarm input and waken the TELIT node
from deep sleep. A value of 0 specifies a
high-to-low transition as active; a value of
1 specifies low-to-high.
ALARM2 POL
Not Supported
1 (low-to-high)
This is the polarity of the transition at
pin RTC_IO_2 that triggers an alarm
input, using the same convention used
for Alarm1.
