# Asio TCP echo server example
|
|
|
|
Simple Asio TCP echo server using WiFi STA or Ethernet.
|
|
|
|
## Example workflow
|
|
|
|
- Wi-Fi or Ethernet connection is established, and IP address is obtained.
|
|
- Asio TCP 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](../../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 TCP message and check it is repeated, for example using netcat `nc IP PORT`.
