Then go down to this line
esp.connect_AP(b'MY_SSID_NAME', b'MY_SSID_PASSWORD')
and change MY_SSID_NAME and MY_SSID_PASSWORD to your access point name and password,
keeping them within the '' quotes. (This example doesn't use the secrets' file, but its also very stand-alone
so if other things seem to not work you can always re-load this. You should get something like the
