Securing a connection between ESP8266 and an MQTT broker

If you don't want to have your own broker, but you want a secure MQTT connection you can use a cloud MQTT instance, such as http://iotcentral.eu.

First create an account on iotcentral.eu and confirm your email address. After that you can log in to iotcental.eu and get your private assigned topic. It is an eight character code, such as c5c05211, and this code needs to precede all of your topics as follows:

c5c05211/living/temperature

No matter if you publish or subscribe. The following code connects to the Wi-Fi and then establishes a secure connection to the iotcentral.eu cloud MQTT over port 8883. Every message sent to the iotcentral.eu broker is received back like a loopback.

Included header files are the ESP8266WiFi and the PubSubClient MQTT class:

#include <ESP8266WiFi.h> 
#include <PubSubClient.h>

GPIO 12 will be used later to blink a LED every time a message is received and GPIO 13 will be changed to HIGH every time a...

Catalin Batrinu

Catalin Batrinu graduated from the Politehnica University of Bucharest in Electronics, Telecommunications, and Information Technology. He has been working as a software developer in telecommunications for the past 16 years. He has worked with old protocols and the latest network protocols and technologies, so he has experienced all transformations in the telecommunication industry. He has implemented many telecommunications protocols, from access adaptations and backbone switches to high-capacity, carrier-grade switches on various hardware platforms from Wintegra and Broadcom. Internet of Things came as a natural evolution for him and now he collaborates with different companies to construct the world of tomorrow that will make our life more comfortable and secure. Using the ESP8266, he has prototyped devices such as irrigation controllers, smart sockets, window shutters, Digital Addressable Lighting Controls, and environment controls, all of them controlled directly from a mobile application over the cloud. An MQTT broker with bridging and a WebSockets server was even developed for the ESP8266. Soon, all those devices will be part of our daily life, so we will all enjoy their functionality.
