Didn’t flash MicroPython on your ESP32 board yet? See How to flash MicroPython to your ESP32 board in 30 seconds
Copy this script and enter your Wifi credentials:
import network
station = network.WLAN(network.STA_IF)
station.active(True)
station.connect("YourWifiName", "EnterYourWifiPasswordHere")Now you need to open a REPL to MicroPython via USB.
If your Wifi is within range of the board and the password is correct, your should see output like
>>> import network
>>> station = network.WLAN(network.STA_IF)
