Abstract

The key idea behind this paper is to implement Modbus RTU protocol on top of FreeRTOS using LPC1768 microcontroller and DragonBoard 410C. Modbus RTU protocol is serial communication protocol which is mainly for industrial applications like Building Management System. This protocol is implemented on top of FreeRTOS, which is a real-time kernel for small embedded systems. A small application is created by using temperature sensor whose output is sent to IoT gateway device by implementing Modbus Serial protocol. DragonBoard 410C is used as gateway device. The temperature data from gateway device is sent to the cloud using ThingsBoard IoT platform.
