6.1.3 Custom Power Save Radio Receive
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.
Command Syntax
AT+WRXPS=n
Parameter Description
Table 120, page 143 describes the Enable/Disable 802.11 Power Save Mode parameters.
Synchronous Response
Table 121, page 143 describes the synchronous responses and remarks for the
Enable/Disable 802.11 Power Save Mode command.
Example AT+WRXACTIVE=0
OK
AT+WRXPS=1
OK
Prior to issuing this command the radio should be off (AT+WRXACTIVE=0), otherwise
there is no effect of power save, if radio receiver is on.
In this case the node will inform the Access Point that it will go to sleep, and the Access
Point will buffer any packets addresses to that node. The node will awaken to listen to
periodic beacons from the Access Point that contains a Traffic Indication Map (TIM) that
will inform the Station if packets are waiting for it. Buffered packets can be retrieved at that
time, using
PSPoll commands sent by the node. In this fashion, power consumed by the
radio is reduced (although the benefit obtained depends on traffic load and beacon timing),
at the cost of some latency. The latency encountered depends in part on the timing of
NOTE: Refer to the AT+WIEEEPSPOLL command for 802.11 power save mode.
