Example 3
AT+WIEEEPSPOLL
This command can be used for three purposes:
–
To configure the Power Save behavior
–
To Enable the Power Save
–
To Disable the Power Save
Configuration of Power Save
To configure the Power Save behavior on the STA, the first
parameter of the command should be 2. The STA can be configured
in 3 ways:
–
Wake up for Listen Interval
–
Wake up for DTIM
–
Wake up for a custom number of beacons
Wake up for Listen Interval
To configure the STA to wake up for the listen interval, the
command is AT+WIEEEPSPOLL=2,10,1. This means that the STA will
advertise in the Association Request that the listen interval
will be for every 10 beacons. Once associated, the STA will wake
up for every 10 beacons.
Wake up for DTIM
To configure the STA to wake up for every DTIM interval, the
command is AT+WIEEEPSPOLL=2,,0. Here we did not specify the
listen interval as that will be the default. In this case, the
STA will advertise the default Listen Interval in the
Association Request. Once associated, the STA will wake up for
every DTIM interval that has been configured on the AP.
Custom Wake up
To configure the STA to wake up at a custom interval, the
command is AT+WIEEEPSPOLL=2,,2,5. Here also, we did not specify
the listen interval, that will be the default. The STA will
advertise the default Listen Interval in the Association
Request. Once associated, the STA will wake up for every 5
beacons.
Difference between Listen Interval based Wake up Versus Custom
Wake up
At the outset, both of these options do the same thing - to wake
the STA based on the number of beacons given.
Either of these options can be used to wake the STA. However,
the use case is as follows:
