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
