ASIO udp echo server example

Simple asio echo server using WiFi STA

Example workflow

  • WiFi STA is started and trying to connect to the access point defined through make menuconfig
  • Once connected and acquired IP address, ASIO udp server is started on port number defined through make menuconfig
  • Server receives and echoes back messages transmitted from client

Running the example

  • Run make menuconfig to configure the access point's SSID and Password and port number
  • Run make flash monitor to build and upload the example to your board and connect to it's serial terminal
  • Wait for WiFi to connect to your access point (note the IP address)
  • You can now send a udp message and check it is repeated, for example using netcat nc -u IP PORT

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