- Wi-Fi or Ethernet connection is established, and IP address is obtained.
build system: Use CMake-based build system as default when describing commands * Original commit: espressif/esp-idf@47bbb107a8deaa80692ebc3b9369ae0618c3bc56
2019-06-23 11:54:31 +10:00
- Asio UDP server is started on port number defined through the project configuration

- Server receives and echoes back messages transmitted from client
## Running the example

- 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 UDP message and check it is repeated, for example using netcat `nc -u IP PORT`.
