1.3. WIFI SCANNING
Open the Arduino IDE and open the example program
`File`->`Examples`->`WiFi`->`WiFiScan`. Connect the device to the computer
and select the corresponding port to burn. After completion, the device will
automatically run the WiFi scan, and the current WiFi scan result can be obtained
through the serial port monitor that comes with the Arduino.
