Flash onto the Device
Flash the binaries that you just built onto your ESP32 board by running:
idf.py -p PORT [-b BAUD] flash
Replace PORT with your ESP32 board's serial port name. You can also change the
flasher baud rate by replacing BAUD with the baud rate you need. The default baud
rate is 460800.
