Introduction
BlueNRG-Mesh connects multiple BLE (Bluetooth Low Energy) devices in Mesh networking for IoT (Internet of Things)
solutions. It integrates BlueNRG products with embedded Bluetooth Low Energy communication in a powerful, range-extending
Mesh network with true full-duplex communication.
The solution contains the core functionality for secure communication and provides the flexibility you need to build applications.
It uses BlueNRG-2, BlueNRG-1, BlueNRG-MS devices with Mesh stack APIs and related event callbacks. The SDK provides
the Mesh stack in library form and a sample application in source code to demonstrate how to use the library.
BlueNRG-Mesh can be used in several applications requiring infrequent data transfer in a mesh network over Bluetooth Low
Energy
, to create distributed control systems such as:
��� smart lighting
• home and building automation
• industrial automation
A demo example is available for the device evaluation boards. You can use it to change the application interface and use the
library for the required hardware and software functionalities. The demo application is available for the following evaluation
boards:
• STEVAL-IDB008V1 and STEVAL-IDB008V2 for BlueNRG-2
• STEVAL-IDB007V1 and STEVAL-IDB007V2 for BlueNRG-1
• X-NUCLEO-IDB05A1 and NUCLEO-L152RE for BlueNRG-MS
The sample application implements Smart Light control scenario, which you may modify according to your requirements.

To connect the STEVAL-IDB008V1 or
STEVAL-IDB008V2 (BlueNRG-2 evaluation board) and PC, a USB port is
required to provide power supply to the board. To connect the ST-Link/V2 debugger, an additional USB port is
needed.
