W55MH32 RT-Thread + UDP Communication Test

Project description

In this article, we will introduce how to implement a loopback test program on the W55MH32 Ethernet chip with the RT-Thread real-time operating system that simultaneously supports dual-mode parallel operation of UDP Server + UDP Client. Through two independent threads handling UDP listening and active sending logic respectively, combined with the W55MH32 hardware protocol stack features, we complete bidirectional data transceiver verification, providing a directly reusable practical solution for embedded multi-role network communication. For other network protocols used in this example, such…
