Research of Communication Between IoT Cloud Structure, Android Application and IoT Device Using TCP Sockets

This paper studies and describes communication between IoT cloud, Android mobile application and IoT embedded systems. It presents a way of transmitting temperature and humidity of the IoT cloud using TCP sockets. A JSON type data format is used between the cloud structure and the devices. Embedded systems STM32L4 discovery and Esp8266 are transmited data to IoT cloud using TCP sockets. Mobile application realizes the representation of temperature and humidity readings from a sensor. Architecture and software implementation of the experimental stage is also presented.
