I have a mqtt broker which does not support websocket connection. I need to write an HTML webpage that will connect to the broker and publish a message string on it. Is it possible to not use websockets through my web page and still connect and publish data? If so, how can I do that?

No, you can not connect to anything from with in a browser with anything other than HTTP or WebSockets.

A possible solution is to set up a separate WebSockets to MQTT bridge between the web page and the broker.

  • WebSockets are a way of connecting to a two way communication pipe, just like a normal TCP socket, but from within a web browser. If you want to use MQTT from within a browser, you need to use a WebSocket. If you are not within a web browser, you don't need WebSockets. – njh Oct 15 '16 at 00:24
