config WIFI_SSID
    string "WiFi SSID"
    default "myssid"
    help
	SSID (network name) for the example to connect to.

config WIFI_PASSWORD
    string "WiFi Password"
    default "mypassword"
    help
	WiFi password (WPA or WPA2) for the example to use.
	
config WIFI_LISTEN_INTERVAL
    int "WiFi listen interval"
    default 3
    help
	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.

choice POWER_SAVE_MODE
    prompt "power save mode"
    default POWER_SAVE_MIN_MODEM
    help
	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 
	for DTIM is determined by AP. 
	In maximum power save mode, station wakes up every listen interval to receive beacon. Broadcast data 
	may be lost because station may be in sleep state at DTIM time. If listen interval is longer, more power 
	is saved but broadcast data is more easy to lose. 

config POWER_SAVE_NONE
    bool "none"
config POWER_SAVE_MIN_MODEM
