After uploading the code from the ESP32 Webserver sample (module 4, unit 2 of my Course) the Serial Monitor is supposed to show the IP number.
Instead it shows square blocks only.
Earlier, with Examples\Wifi\Wifiscan I had the same problem.
I use the DOIT ESP32 DEV KIT V1
Appreciate your help.

Hi.
You probably don’t have the right baud rate selected on the serial monitor.
Double-check that it is selected to 115200 baud at the bottom right corner.

Thank you, Sara.
The baudrate was set incorrectly.
Examples\Wifi\Wifiscan runs ok now, however with the ESP32 Webserver sample a new issue has popped up.
The Wifi.status remains “Not Connected” and the Serial Monitor shows more and more dots.
This is the code where the programs “hangs”:
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(“.”);
Your suggestions are welcome.

Hi Antonio.
If you keep getting dots on the Serial Monitor that means that the ESP32 is not able to connect to your network.
This can be caused:
- if you didn’t insert your network credentials
- if you inserted your network credentials wrong (misspelling)
- the ESP32 is very far away from your router and it is not able to pickup the wi-fi signal.

Sara,
You were right again.
Misspelled network credential.
Thank you for your swift response.
