Getting started with X-NUCLEO-IDB05A1 BLE expansion board

based on the SPBTLE-RF module for STM32 Nucleo

Introduction

The X-NUCLEO-IDB05A1 is a Bluetooth Low Energy evaluation board based on BlueNRG-MS RF

module, SPBTLE-RF, to allow expansion of the STM32 Nucleo boards. The SPBTLE-RF module is FCC

(FCC ID: S9NSPBTLERF) and IC certified (IC: 8976C-SPBTLERF). The BlueNRG-MS is a very low

power Bluetooth Low Energy (BLE) single-mode network processor, compliant with Bluetooth

specification v4.1. X-NUCLEO-IDB05A1 is compatible with the ST Morpho and Arduino UNO R3

connector layout.

This expansion board can be plugged into the Arduino UNO R3 connectors of any STM32 Nucleo

board. The user can mount the ST Morpho connectors if required. The different expansion boards can

be easily stacked to allow evaluation of different devices with Bluetooth Low Energy connectivity.

The board has the following features:

On-board SPBTLE-RF module based on the BlueNRG-MS single mode BLE network processor

SPI EEPROM for parameter saving

Jumper at 3V3 for checking the current consumption of STM32 expansion board

1 Getting started

This section describes the hardware requirements for the X-NUCLEO-IDB05A1 evaluation

board.

1.1 Hardware requirements

The X-NUCLEO-IDB05A1 is an expansion board for use with STM32 Nucleo boards. To

function correctly, the X-NUCLEO-IDB05A1 must be connected to the STM32 Nucleo

board as shown in Figure 2: "X-NUCLEO-IDB05A1 plugged into an STM32 Nucleo board

through the Arduino UNO R3 connector" below.

The STM32 Nucleo firmware and related documentation is available at

http://www.st.com/stm32nucleo

Figure 2: X-NUCLEO-IDB05A1 plugged into an STM32 Nucleo board through the Arduino UNO

R3 connector

The interconnection between the STM32 Nucleo and the X-NUCLEO-IDB05A1 has been

designed to permit the use of any STM32 Nucleo board, although complete testing has

been performed using the NUCLEO-L053R8 hosting the ultra-low power STM32, and the

NUCLEO-F401RE hosting the dynamic efficiency STM32.

1.2 System requirements

Using the Nucleo boards with the X-NUCLEO-IDB05A1 expansion board requires the

following software and hardware:

Windows PC (XP, Vista, 7, 8) to install the firmware package

USB type A to Mini-B USB cable to connect the Nucleo board to the PC

Installation of the board firmware package (order code: X-CUBE-BLE1) and the BlueNRG

graphical user interface utility on the user's PC requires the following:

Figure 2: "X-NUCLEO-IDB05A1 plugged into an STM32 Nucleo board through the

Arduino UNO R3 connector"

3. Power the Nucleo board using the Mini-B USB cable

4. Program the firmware in the STM32 on the Nucleo board using the firmware example

provided

5. Reset the MCU board using the reset button available on the Nucleo board

6. The evaluation kit is ready to be used

2 Hardware description

This section describes the X-NUCLEO-IDB05A1 features and provides information which

could be useful to understand the board schematic diagrams.

2.1 X-NUCLEO-IDB05A1 board

The board allows the user to test the functionality of the SPBTLE-RF module. The

SPBTLE-RF hosts the BlueNRG-MS, a very low power Bluetooth Low Energy (BLE) single-

mode network processor, compliant with Bluetooth specification v4.1. The module also

embeds the innovative BALF-NRG-01D3 (balun with integrated harmonic filter) and a chip

antenna.

Its functionality can be exploited using the firmware package contained in the X-CUBE-

BLE1. It is fundamental to program the microcontroller on the STM32 Nucleo board. Please

refer to user manuals UM1724 and UM1725, available on www.st.com.

The SPBTLE-RF module and the STM32 Nucleo board are connected through connectors

CN5, CN6, CN8 and CN9 (see Table 1: "Interconnection between STM32 Nucleo board

and X-NUCLEO-IDB05A1 left-side connectors" for details). The pins indicated with an

asterisk (*) allow an alternative pin for that specific function, i.e. SPI_IRQ could be moved

from CN8.1 to CN5.2.

2.2 SPI and GPIO connection options

Table 3: "BlueNRG-MS interface (optional) with the STM32 Nucleo board" shows the SPI

and GPIO connection options between the STM32 and BlueNRG-MS hosted on the

SPBTLE-RF module. These can be used for operation of the board in different

configurations in cases where different expansion boards are utilized and there is a conflict

of signals.

resources to be used.

2.3 Current measurement

To monitor the power consumption of the BlueNRG-MS X-NUCLEO-IDB05A1 board, insert

an ammeter probe between pins 1 and 2 of the jumper on the J1 connector. Since the

power consumption of BlueNRG-MS is very low during most of its operating time, an

accurate instrument in the range of a few µA may be required.
