Here I am showing my demo of MQTT Client running on STM32F051 and W5500 as Ethernet device. The MQTT Client is based on Paho open source MQTT Client. I have ported it for STM32 and W5500. From my client I am publishing a message every second to a topic. And on My Android phone I am using MyMQTT to subscribe to the same topic so that I can view the messages there.
