13- Open the project configuration menu (`idf.py menuconfig`) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.
14- Set server port number in menuconfig, "Example configuration".
15- Run `idf.py -p PORT flash monitor` to build and upload the example to your board and connect to it's serial terminal.
16- Wait for the board to connect to WiFi or Ethernet (note the IP address).
