WiFiClientConnect Example

This example demonstrates how to connect to the WiFi and manage the status and disconnection from STA.

Supported Targets

Currently, this example supports the following targets.

Supported Targets ESP32 ESP32-S2 ESP32-C3

How to Use Example

Using Arduino IDE

  • Before Compile/Verify, select the correct board: Tools -> Board.
  • Select the COM port: Tools -> Port: xxx where the xxx is the detected COM port.

Using Platform IO

  • Select the COM port: Devices or set the upload_port`` option on the platformio.ini` file.

Troubleshooting

Important: Be sure you're using a good quality USB cable that has enough power for your project.

  • Programming Fail: If the programming/flash procedure fails, try to reduce the serial connection speed.
  • COM port not detected: Check the USB cable connection and the USB to Serial driver installation.

If the error persists, you can ask for help at the official ESP32 forum or see Contribute.
