Overview

The BlueNRG-M2 is a Bluetooth® low energy system-on-chip application processor certified module, compliant with BT specifications v5.0 and BQE qualified. The BlueNRG-M2 module supports multiple roles simultaneously and can act at the same time as Bluetooth master and slave device. The BlueNRG-M2 is based on the BlueNRG-2 system-on-chip and entire Bluetooth low energy stack and protocols are embedded into module. The BlueNRG-M2 module provides a complete RF platform in a tiny form factor. Radio, embedded antenna and high frequency oscillators are integrated to offer a certified solution to optimize the time-to-market of the final applications. The BlueNRG-M2 can be powered directly with a pair of AAA batteries or any power source from 1.7 to 3.6 V.

Operating Modes

There are two possible software architectures:

1. Host-less mode (application processor): customer application runs on the BlueNRG-M2 module:

Body Image 3-STMicroelectronics BlueNRG-M2

2. Hosted mode (network processor): the module is configured as network module controlled by an external host connected via SPI or UART. A project named DTM is available in the development kit that configures the BlueNRG-M2 module as a network module:

Evaluation Boards

  • •  X-NUCLEO-BNRG2A1: Bluetooth Low Energy expansion board based on the BLUENRG-M2SP module for STM32 Nucleo ODE, with BlueNRG-M2 Wireless SoC acting as Network Processor

  • Body Image 5-STMicroelectronics BlueNRG-M2

    The X-NUCLEO-BNRG2A1 expansion board provides Bluetooth low energy connectivity for developer applications and can be plugged onto an STM32 Nucleo development board (e.g., NUCLEO-L476RG with ultra-low power STM32 microcontroller) through its Arduino UNO R3 connectors.

  • •  STEVAL-IDB008V1M: Evaluation platform based on the BlueNRG-M2SA module

  • Body Image 6-STMicroelectronics BlueNRG-M2

    The STEVAL-IDB008V1M provides a set of hardware resources for a wide range of application scenarios: sensor data (accelerometer, pressure and temperature sensors), remote control (buttons and LEDs) and debug message management via USB virtual COM. Three power options are available (USB only, battery only and external power supply plus USB) for application development and testing flexibility.
