Asio chat server example

Simple Asio chat server using WiFi STA or Ethernet.

Example workflow

  • Wi-Fi or Ethernet connection is established, and IP address is obtained.
  • Asio chat server is started on port number defined through the project configuration.
  • Chat server echoes a message (received from any client) to all connected clients.

Running the example

  • Open 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).
  • Connect to the server using multiple clients, for example using any option below.
    • build and run asi chat client on your host machine
    • run chat_client asio example on ESP platform
    • since chat message consist of ascii size and message, it is possible to netcat nc IP PORT and type for example 4ABC<CR> to transmit 'ABC\n'

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