Hello,
I cannot get my QT Py ESP32-C3 WiFi board to connect to WiFi using the following:
WiFi.begin(ssid, password);
Serial.print("\nConnecting to WiFi");
Serial.println(wifi_status);
while(WiFi.status() != WL_CONNECTED){
Serial.print(".");
delay(1000);
}
I am able to connect to WiFi using other ESP32 boards.
Does this indicate a faulty board?

Re: QT Py ESP32-C3 won't connect to WiFi
Just to confirm you are using this example code with your username and YOUR_SSID* fields customized?
https://learn.adafruit.com/adafruit-qt- ... st-3077319
If the above is not working are you able to run the WiFi Scan?

Re: QT Py ESP32-C3 won't connect to WiFi
Yes, I have tried the example at the link with correct SSID & PASSW.
Interestingly, Wifi Scanner does find all my available networks.
I tried 2 different SSIDs with no success.
