ESP32 Firmware Update

When updating firmware for the ESP32, you will need to make sure you select the port that the WiFi Function Board is connected on. It should be the port that is connected to the CP2102. In this case, the port was named as Silicon Labs CP210x USB to UART Bridge under COM11 under the Windows Device Manager.
