problems connecting to a hidden wifi network with MAC authentication. neither a username nor a password is required
Any suggestions on how to fix it?

Hi @hansj,

not sure if this use case is supported by the ESP WiFi library.

I would try to do everything as for WiFi networks with PSK authentication and enter the name for hidden WiFi network, but leave the WiFi password empty in this step: https://youtu.be/DH3zN3nLk9w?t=144 Before make sure the the MAC address of the ESP is allowed access.
But apart from that I have no ideas, I never used a WiFi with MAC authentication.

Greetings!

Hi @toblum
Thanks for the quick response, I'm relatively new to this so I hope these aren't stupid questions.
have tried with a blank password without success.
tried with an example(WiFiClientConnect) of simple wifi connection from arduino ide set wifi ssid without password and it connected immediately. so I wonder where I can find connection to wifi in the code. I've searched but can't figure out which library is in use

The project uses the https://github.com/prampec/IotWebConf library for WiFi connection handling. So you might find a hint there.
