STM32F4 Discovery: MQTT protocol Embedded program?

Question asked by nguyen.dong.002 on Jul 10, 2016
Dear friends, I am having a STM32F4 discovery board and I am trying my best to complete my home automation project. I want to send my sensors' data to a web server (particularly adafruit.io) as well as control relays from that server. But I am so confused how I can program the mqtt protocol on my kit. Can anyone give me an example how to update sensors' data to that server and get the controlling command from that server?
 As far as I know we can use MQTT protocol to resolve the matter but I do not know that is there any Wifi module/ Ethernet shield could be used in the project? Can someone show me?
Thanks in advance! I hope you could help me!
Sincerely.
