Hi Cristian.
Can you provide more details about what you’re trying to achieve?
Also, what do you have built so far? Do you get any errors? 
Do you want something like a “Wi-Fi Manager”?

I’m guessing Cristian would like to be able to select the WiFi SSID to connect to somehow rather than hard coding into the sketch. That’s something I would like to be able to do as well.
i have been theorizing on it. I believe the preferences library is what we need to use. In the setup function check whether there is an SSID and password. If not create a soft access point and web page at 192.168.4.1 that will show all WiFi SSIDs in range probably in a pop up menu. Then you need a text box for the password. Once submitted try to connect. If that works save to preferences and reboot the ESP32. Now it’s available the setup function can directly connect.

You can follow this discussion for more information: https://rntlab.com/question/esp32-wifimanager/
Unfortunately, we don’t have a complete example about setting that up.
You’ll probably need to combine some of our tutorials to do that.

I found this which looks up to date and has extensive documentation.

Thanks for sharing 🙂

I thank everyone for the help, I will try the one that Steve makes, of all the ones that I tried the most versatile is <https://github.com/Hieromon/AutoConnect> and the last update is three months ago.
I will keep testing and comment if there is one that works better.
Regards

You can also develop it yourself!
It’s an excellent exercise 😉
The icing on the cake is to implement a captive portal as well…

Thanks for that link Christian. I’ll check it out.
 
I’m not a big fan of reinventing the wheel and will use other examples to build by own. I will probably take bits from both of these and toss out the bits I don’t need.
