And upload this example to your board. The ESP32 should scan and find WiFi
networks around you.
For ESP32, open the serial monitor, to see the scan begin.
For ESP32-S2, -S3 and -C3, don't forget you have to click Reset after uploading
through the ROM bootloader. Then select the new USB Serial port created by the
ESP32. It will take a few seconds for the board to complete the scan.
If you can not scan any networks, check your power supply. You need a solid power
supply in order for the ESP32 to not brown out. A skinny USB cable or drained battery
can cause issues.
