QT Py ESP32-C3 won't connect to WiFi

Post by ajscam »

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?

Just to confirm you are using this example code with your username and YOUR_SSID* fields customized?

void printWifiStatus() {
  // print the SSID of the network you're attached to:
  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());

  // print your board's IP address:
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);

  // print the received signal strength:
  long rssi = WiFi.RSSI();
  Serial.print("signal strength (RSSI):");
  Serial.print(rssi);
  Serial.println(" dBm");
}
If the above is not working are you able to run the WiFi Scan?
Load up the WiFiScan example under Examples->Examples for YOUR BOARDNAME->WiFi->WiFiScan

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.

Code: Select all

13:08:27.749 -> Nr | SSID                             | RSSI | CH | Encryption
13:08:27.749 ->  1 | A                                |  -51 |  6 | WPA2+WPA3
13:08:27.788 ->  2 | B                                |  -51 |  6 | WPA2
