Hi, a bare metal WebSocket echo server for Ell-i can be found here: http://github.com/ElPopularVale/Ell-i-Websocket-Bare-Metal Supports WebSocket messages without fragmentation and short payloads. This application allows bidirectional communication between Ell-i and a web browser. Application level protocols can be built on top of WebSocket, such as symmetric encryption, chat, audio/video, midi. It could also be used as a HTML5 based GUI for Ell-i. -Jose Granados MSc Student.
