1# Asio TCP echo server example 2 3Simple Asio TCP echo server using WiFi STA or Ethernet. 4 5## Example workflow 6 7- Wi-Fi or Ethernet connection is established, and IP address is obtained. 8- Asio TCP server is started on port number defined through the project configuration. 9- Server receives and echoes back messages transmitted from client. 10 11## Running the example 12 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). 17- You can now send a TCP message and check it is repeated, for example using netcat `nc IP PORT`. 18 19See the README.md file in the upper level 'examples' directory for more information about examples. 20
