Hello, i have a problem with WifiManager in my ESP32 Devkit. When i want to connect my ESP32 with WiFi using AP Mode, in serial monitor always show the error like this :
*wm:[ERROR] Connect to new AP Failed
Im so very confused, the password that I typed in the SSID that I chose is already correct, but the AP mode is still error and cannot connect to the WiFi SSID selected.
For the information, in this project i use a 2 core management and use a Menu Library, so if i want to use a WiFiManager I have to access the Wifi Manager menu on my device using the keypad.
i have put a snippet program code below.
I hope there is a solution to my problem, thank you!
