We're trying to use MQTT over websockets, however, it doesn't seem that the Sming MQTTClient supports connections over websockets. Any idea if there's anything else available?

Could we use the WebSocketClient to send MQTT messages? Is there any reference of how to format those messages to subscribe etc?

Regards,

Alex

Peter Scargill has done a lot of work on using MQTT with Node Red and websockets. See this:-

This is page one of a three page blog, be sure to read the other pages.

Since MQTT brokers support web sockets, there's no reason for the ESP not to have an MQTTWebSocket client. It's just a matter of someone developing one, or porting one.

Does anyone have a reference of how to construct MQTT Web Socket messages (subscribe, publish, etc)?

Alex
