General description

The BlueNRG-M0 is a single-mode Bluetooth low energy master/slave network processor module compliant with

Bluetooth® v4.2.

The BlueNRG-M0 module has been designed around the ST BlueNRG-MS network processor, on which a

complete power-optimized stack for Bluetooth single mode protocol runs, providing

•

Master, slave role support

•

GAP: central, peripheral, observer or broadcaster roles

•

ATT/GATT: client and server

•

SM: privacy, authentication and authorization

•

L2CAP

•

Link Layer: AES-128 encryption and decryption

The BlueNRG-MS radio embeds non-volatile Flash memory allows on-field stack upgrading. In addition,

according to the Bluetooth specification v4.2, the BlueNRG-M0 module provides:

•

Multiple roles simultaneously support

•

Support simultaneous advertising and scanning

•

Support being slave of up to two masters simultaneously

•

Privacy V1.1

•

Low duty cycle directed advertising

•

Connection parameters request procedure

•

LE Ping

•

32 bits UUIDs

•

L2CAP connection oriented channels

The BlueNRG-M0 module is equipped with Bluetooth low energy profiles in C source code, available for the ST

radio BlueNRG-MS.

The external host application processor, where the application resides, is interfaced with the BlueNRG-M0 module

through an application controller interface protocol, which is based on a standard SPI interface.

The BlueNRG-M0 module enables wireless connectivity into electronic devices, not requiring any RF experience

or expertise for integration into the final product. The BlueNRG-M0 module provides a complete RF platform in a

tiny form factor and being a certified solution optimizes the time-to-market of the final applications.

The BlueNRG-M0 module allows applications to meet of the tight advisable peak current requirements imposed

with the use of standard coin cell batteries. Optimized results are obtained when the embedded high-efficiency

DC-DC step-down converter is used (BLUENRG-M0A). Instead, concerning the BLUENRG-M0L the best

performance in terms of power consumption is achieved using a 1.8V DC power supply.

The BlueNRG-M0 can be powered directly with a standard 3 V coin cell battery, a pair of AAA batteries or any

power source from 1.7 to 3.6 V.

ST may update the FW provided with the modules at any time. ST recommends that users regularly check for

documentation and the current FW version available at www.st.com/bluemodules.
