How to enable Websockets in Mosquitto MQTT broker?

hi welcome to donkey Tech in short video will show you how to enable mqtt over web sockets using the mosquito broker so the question is why do we need to enable websockets in mqtt well the mqtt protocol by default does not operate on your web browser so the solution is to send a 15 qtt messages wrapped in web socket and below the majority of the latest browsers support the websocket protocol so this is a viable option the messages are exchanged with the mqtt pocket wrapped inside the websocket and below which in turn is set to the TCP IP envelope the receiver and packs its each envelope until it sees the mqtt packet you can Envision that it will be easier to create internet of this application in the browser that uses MPT communication protocol to the web sockets now I have here my mosquito mqtt broker running and as you can see it has a message that it is listening to websocket Port 9001 now the changes are really simple on how to enable this and all you have to do is to edit your mosquito.com app and hide this line so this is my mosquito.com app and I just added the following lines foreign broker using this option the socket domain option is usable if your network config is using ipv4 or change this to ipp6 now after doing that changes all you have to do is execute this command mosquito Dashi foreign the next question is how do we do the testing of our mqtt over web sockets then to do that I'm using a tool called The mqtt X which is a tool available in major operating system such as the windows Linux or the map all you need to do is to download the appropriate installer for you and then run the application once the application is run all you have to do is to click the new connection after clicking the add the new connection just hit set the name and then the host will be ws and the IT address would be the IP address of my mosquito aggregative broker which is currently the Windows PC that I'm running the port is 9001 and then you just need to click the connect button you see message is now connected which means that I am able to communicate with my mosquito broker if we take a look at my mosquito broker you would mess you would see that there is a new that client that has connected in this port now once we have the connection the next thing to do is to subscribe to particular topic to do that just click the new subscription and then we're going to subscribe to the temperature okay and then just accept the default and then click the confirm button so right now I am connect with the temperature is in this one what I'm going to do is I'm going to create a client that will publish in this mosquito broker so what we're going to do is publish the using the tool mosquito Pub and the version is mpt311 the topic is temperature and the message is 10 F or 10 degree Fahrenheit if I click enter and as you can see there was a message and then the publish was done in the mosquito broker it says that it is successfully published then let's check our mptx app now as you can see in my mqtt X app you would notice that I have received the topic the message that and the topic is temperature the message was successfully received so which means that our setup for the mosquito activity over websocket was successful in the future we will be using concept discussed here in an Internet of Things project until then app exploring foreign [Music]
