- Wed Nov 18, 2015 8:42 am #34412 I was happily working on my project collecting data form ESP01 sensors and sending to my local ESP server...
Then I came across MQTT and thought I'd modify my set-up and use it but I'm completely lost...

Before getting to the client side (coding my ESP01's to add MQTT), I first need to set up my local server to implement MQTT but this part is causing me no end of confusion... In all honesty I don't know where to start...

To simplify things I considered using Mongoose (the pro version of which includes an MQTT broker) but that won't suit everyone so, I'd rather try to implement the broker using opensource only but I can't find any example code or tutorials...

Can anyone give me suggestions on where I should start or point me in the right direction please...

I spent a few days working this out. I left the ESP 8266 out of the equation initially just to get the server and whatever router infrastructure proven out first.

I used an old EEEPC 900 netbook as my server and installed ubuntu linux. I had a ton of difficulty with other light distributions on an old dell desktop and eventually gave up on it. I installed and configured moquitto MQTT broker (http://mosquitto.org/). I also installed the apache web server to be able to easily check if my network and stuff were all working correctly.

On my normal windows 7 PC, I installed Eclipse Paho MQTT Client (http://www.eclipse.org/paho/) in order to test out the server operation and figure out how the MQTT subscribe and publish messages work.

Once I got all the pieces in place, it all worked pretty easily. Eventually, I put the MQTT stuff from the SDK onto my ESP8266-01 and fired it up. I was able to publish stuff to the mosquitto server and see it get relayed to the Paho client on my PC. I haven't gotten around to modifying the MQTT code on the ESP to do anything useful yet, but the basic demo works like its supposed to.

Hope this helps.

I will read your post and see if I can figure out what to do next, then I will edit this post and add some more details... need to grab some sleep now and just thought I say thanks before I tie myself up in knots...
