Previously set to wait until IP address got from tcpip_adapter, but since common example connect code blocks until both IP4 and IPv6 address received it could happen that test code might have started connection to the ASIO counter-part while ESP32 still waiting for IPv6 address |

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