David Cermak 8d90156c07 asio: fix asio test code to start the test after ip address received from common example code 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		2019-11-14 12:12:15 +08:00

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.

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.
