# WiFiScan Example
This example demonstrates how to use the WiFi library to scan available WiFi networks and print the results.
This example shows the basic functionality of the dual antenna capability.
# Supported Targets
This example is compatible with the ESP32-WROOM-DA.
## How to Use Example
* How to install the Arduino IDE: [Install Arduino IDE](https://github.com/espressif/arduino-esp32/tree/master/docs/arduino-ide).
#### 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 and you have enough power source 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](https://esp32.com) or see [Contribute](#contribute).
