Project description

In this WCC, we will use the TCP server multi-socket example. WIZnet's W5500 chip can open up to 8 sockets, while the W5100S can open up to 4 sockets. The w55rp20, which we’re using today, also allows up to 8 sockets. Use Cases for Multiple TCP Sockets 1. Handling Multiple Clients Simultaneously Each client needs an independent communication channel with the server. ex) Chat applications, multiplayer games, web servers. 2. Separation of Data Types Different sockets can handle control signals (e.g., commands) and data streams (e.g., file transfer) separately for better organization. ex) Video…
