Djordje Nedic facab8c5a7 tools: Increase the minimal supported CMake version to 3.16
This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.

Asio UDP echo server example

Simple Asio UDP echo server using WiFi STA or Ethernet.

Example workflow

  • Wi-Fi or Ethernet connection is established, and IP address is obtained.
  • Asio UDP server is started on port number defined through the project configuration
  • Server receives and echoes back messages transmitted from client

Running the example

  • 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 for more details.
  • Set server port number in menuconfig, "Example configuration".
  • Run idf.py -p PORT flash monitor to build and upload the example to your board and connect to it's serial terminal.
  • Wait for the board to connect to WiFi or Ethernet (note the IP address).
  • You can now send a UDP message and check it is repeated, for example using netcat nc -u IP PORT.

See the README.md file in the upper level 'examples' directory for more information about examples.
