ESP32-C3-Mini Wifi Problems
Posted: Wed Aug 28, 2024 1:55 pm
Hello, I apologize in advance if I make any mistake, is that I am new to this forum.
I have an ESP32-C3-Mini on my own PCB and the problem I have is that when I run some code that contains some Wifi function it does not execute it. The only Wifi function that I run is the Wifi Status function.
As you can see in one of the example code that I provided. The program executes the first print but once it does the “WiFi.mode(WIFI_STA);” it stops executing and does not do the second print.
Has anyone had or knows how to solve this problem?
Thank you very much

* This sketch demonstrates how to scan WiFi networks.
* The API is based on the Arduino WiFi Shield library, but has significant changes as newer WiFi functions are supported.
* E.g. the return value of encryptionType() different because more modern encryption is supported.
