Research of Communication between STM32L475 and Private Cloud realized by using Amazon FreeRTOS and MQTT

Abstract

This paper studies and describes communication between IoT cloud and IoT embedded system with STM32L475 microcontroller. Described are advantages and limitations of Private and Public IoT Cloud. It is used for experimennts MQTT protocol, Private IoT Cloud and Amazon FreeRTOS A JSON type data format is used between’ the cloud structure and IoT device.. Architecture and software implementation of the experimental stage is also presented.
