lwip_ipv4_ipv6_echo_enet_qos_freertos
Overview
The lwip_ipv4_ipv6_echo demo application demonstrates a TCP or UDP echo demo on the lwIP TCP/IP stack with FreeRTOS. The demo uses the TCP or UDP protocol over both IPv4 and IPv6 and acts as an echo server. The application sends back the received TCP or UDP packets from the PC, which can be used to test whether a TCP or UDP is available.
