Example 4
Whenever the STA is needed to wake up at some configured
interval, the Custom Wake up option should be used. While
configuring the custom wake up parameters, the listen interval
should not be entered; the default listen interval will be used
in the association request. Usually, in the association request,
the STA will advertise the listen interval as a large value
(e.g., 10 beacons). The configuration of the custom wake up
interval will be less than the listen interval (e.g., 5
beacons). In this case, the STA bluffs to the AP while
associating telling that it will wake up for every 10 beacons.
But, in reality, it will wake up for every 5 beacons. This is
just to ensure tha
t the AP shouldn’t drop the buffered frames in
case the PS Poll request from the STA does not reach the AP.
Enable Power Save:
To enable the power save on the STA, the command is
AT+WIEEEPSPOLL=1. Whenever AT+WIEEEPSPOLL is given as 1, the STA
will take the last power save configuration into effect. So, the
user should first configure the behavior and then enable the
power save.
Disable Power Save
:
To disable the power save on the STA, the command is
AT+WIEEEPSPOLL=0. When this command is executed, the radio is
fully off. Order of Precedence between commands - WRXACTIVE >
WRXPS > WIEEEPSPOLL.
9.1.3.
Custom Power Save Radio Receive
Command Description
This command is used to enter Power Save Mode. Once enabled, radio will be switched
off (after informing AP) when ever possible (e.g., in between beacons intervals, when
there is no data transmission). Since module inform AP about its inactivity, AP shall
buffer all the incoming unicast traffic during this time.
Note/Tip: Refer to the AT+WIEEEPSPOLL command for 802.11
power save mode.
