From what you describe you did not use "web sockets" but simply "sockets", e.g. direct TCP/IP.

After establishing the connection (server sends response with code 101) the WebSocket connection has their own framing and scrambling of the data, so you cannot just use it with the normal socket tools.

See https://www.rfc-editor.org/rfc/rfc6455 for the specification and use "WebSockets" as the keyword if you look for more documentation, usage...
