maybe this is a dumb question, but is there a way to test for wrong wifi password,
I know you can do WL_CONNECT to check if the password works, but is there a command for checking if the password is wrong? not just by waiting.
The information is available on SDK level. If you include
#include "user_interface.h", you can use function
wifi_station_get_connect_status(). It returns one of:
STATION_GOT_IP STATION_NO_AP_FOUND STATION_CONNECT_FAIL STATION_WRONG_PASSWORD STATION_IDLE
WiFi.status() function uses function
wifi_station_get_connect_status(), but returns WL_CONNECT_FAILED for STATION_WRONG_PASSWORD.
