Cannot connect from browser to native MQTT

[PaulCorbeau]

Hello,

I try to access directly a MQTT broker on port 1883, without websocket from a browser.

When I check the object result I can see that the protocol is not changed to mqtt nor tcp :

I found that some settings can be change with the option : wsOptions. I tried to create manually the Websocket but it indicates that it accepts only ws or wss.

Am I missing something ?

thanks

Port 1883 is for MQTT protocol, which is different to MQTT over Websockets. Your broker needs to support MQTT over websockets, and this will usually be running on a different port, maybe 80, 8080, 8883 (I don't believe there is a 'default' universally used like 1883 is for MQTT). Basically MQTT.js through a brower only supports "MQTT over websockets" and not 'native' MQTT protocol.
