Hi, I am starting a new project for IoT , and I am wondering if someone has already been working on it, the idea is to have devices connected using mqtt protocol. Any ideas or suggestions are wellcome, my starting point will be creating the mqtt library for CCS and then start playing with it. Hope to have some news soon to share. thanks a lot in advance.

OK, I had to Google 'mqtt' just to see what it is. Yikes....looks like some tcp/ip variation...I find it 'interesting' as 'they' say it's simple, lightweight, etc.
As a 'starting' point, I'd buy a couple mqtt 'sensors' and whatever PC software to see 'how it works'. Then get some PIC based tcp/ip board and then try to cut code. Maybe there's a 'kit' out there for a PC based 'test system'?
Trying to develop any PIC software without real hardware ain't going to work! You must have a solid 'reference' to begin with.

good luck

You´re absolutely right. I have already started with a server running mqtt, an *duino sensor reporting temp & humidity.

Now I should go down to packets level, so I will go with ethereal or anything like to debug packets. And test some mqtt clients , Let's see how it works and how hard is it.
Thanks a lot...
