2.10.2.1 Legacy Power Save

In this mode, the behavior of the CC33xx device depends on whether it is acting as a STA or AP, but in either case it will act in a manner consistent to the protocol described below.

In this power saving protocol, when a STA detects that the AP has data for it in the beacon frame, it sends a trigger packet named PS-POLL to the AP. In response, the AP sends the first queued frame to the STA; if the More Data field in this frame is on, it sends another PS-POLL frame to the AP. The STA continues to send PS-POLL frames to receive all the queued frames, until there are no data packets left. After this, the station returns to sleep until the next listening interval.

This method is suitable for very low data usage, since it requires additional overhead to receive each packet.
