Interval for station to listen to beacon from AP. The unit of listen interval is one beacon interval.
For example, if beacon interval is 100 ms and listen interval is 3, the interval for station to listen
to beacon is 300 ms.

Power save mode for the esp32 to use. Modem sleep mode includes minimum and maximum power save modes.
In minimum power save mode, station wakes up every DTIM to receive beacon. Broadcast data will not be
lost because it is transmitted after DTIM. However, it can not save much more power if DTIM is short
