I am currently working on a project in which I use ESP8266 wifi modules with mqtt. I use a mosquitto broker installed on my computer.
I am trying to make more than one esp8266 modules subscribe to a certain topic on the broker. I am using two modules as a demo.
The problem is that whenever I connect one of the modules, the other one disconnects from broker. When I re-connect it the first module (that has just been connected) goes offline.
Any help?
You need to use unique client ids for each module. The broker will kick the first client off when the second connects with the same client id
