Overview

Modbus is an application protocol for serial data transmission that often uses RS-485 for serial data transfer. This reference design implements a gateway between Modbus and the Bluetooth® Smart CC2540 wireless MCU. It serves as a replacement for wires in an RS-485 network, and it allows another Bluetooth® Smart-compatible device like a computer or smartphone to easily connect to an existing RS-485 network.

Features
  • Implements wireless connection to industrial electronic devices with the CC2540T Bluetooth Smart Gateway solution graded up to 125°C
  • Simple and "ready to go" design shortens time to market
  • Android app (ModbusController) provided to enable control and communication with Modbus peripheral software
  • This design is tested and includes firmware, GUI, demo and user guide
