Hi @Usman Khan , so far in NetX Duo, we don't have an existing websocket server implementation now. So you may have to implement it on top of the TCP for it.
Here are a couple of links might be useful:
- WebServer with NetX Duo on STM32U5, it's actually part of the official STM32U5 package
- STM32 WebSocket Server Realization
- mWebSockets
