General description

The SPBTLE-RF is a single-mode Bluetooth low energy master/slave network processor

The SPBTLE-RF B-SmarT module integrates a 2.4 GHz RF radio the ST BlueNRG-MS 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 nonvolatile Flash memory allows on-field stack upgrading.

In addition, according the Bluetooth specification v4.1 the SPBTLE-RF B-SmarT 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 SPBTLE-RF B-SmarT 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

SPBTLE-RF B-SmarT module through an application controller interface protocol, which is

based on a standard SPI interface.

The SPBTLE-RF B-Smart module enables wireless connectivity into electronic devices, not

requiring any RF experience or expertise for integration into the final product. The SPBTLE-

RF B-Smart 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 SPBTLE-RF B-SmarT 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.

SPBTLE-RF 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.
