Getting started with the Sub-1 GHz expansion board based on

SPSGRF-868 and SPSGRF-915 modules for STM32 Nucleo

Introduction

The X-NUCLEO-IDS01A4 and X-NUCLEO-IDS01A5 are evaluation boards intended to

provide a platform for testing the features and capabilities of the SPSGRF modules, based

on the SPIRIT1 low data rate, low power sub-1 GHz transceiver device.

These expansion boards can be plugged into the Arduino UNO R3 connectors of any

STM32 Nucleo board. The user can mount ST Morpho connectors if required. Other

expansion boards can easily be stacked to allow evaluation of different devices using sub-1

GHz communication.

The boards are equipped with the following features:

•On-board SPSGRF module based on the SPIRIT1 sub-1 GHz transceiver device

•SPI EEPROM for saving parameters

•LED for user interface

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

UM1872 Description

1 Description

The X-NUCLEO-IDS01A4 and X-NUCLEO-IDS01A5 boards contain the module SPSGRF-

868 or SPSGRF-915 based on SPIRIT1 low data rate, low power sub-1 GHz transceiver.

The PCB layout is the same for both boards, with the only difference being the module used

with it.

Identification of the RF communication frequency can be easily performed using the

identification resistors (R14 or R15) mounted on the PCBs. Only 1 of the two resistors is

mounted on the board to ensure quick identification. This information is also available in the

PCB silk screen.

Note that R14 and R15 are for identification purposes only, and changing these resistors

does not change the RF frequency of the SPIRIT1 device.

For information common to both boards, the nomenclature “X-NUCLEO-IDS01Ax” is used

hereafter in this document.

1.1 Typical applications

The evaluation boards can be used for evaluation of the SPIRIT1 device in multiple

applications.

The following demo examples are available for testing with the evaluation boards

•wM-Bus: Wireless Metering Bus demo

•Point-to-point communication protocol demo

Please refer to the data brief for the firmware, available on www.st.com.

Users can develop other applications for evaluating the devices. Some of these applications

are:

•Automatic meter reading

•Home and building automation

•WSN (wireless sensor network)

UM1872 Getting started

2 Getting started

This section describes the hardware requirements for the X-NUCLEO-IDS01Ax evaluation

boards.

2.1 Hardware requirements

The X-NUCLEO-IDS01Ax is an expansion board for use with the STM32 Nucleo. To

function correctly, the X-NUCLEO-IDS01Ax must be connected to the STM32 Nucleo board

as shown in Figure 2 below.

The STM32 Nucleo firmware and related documentation is available on www.st.com at

http://www.st.com/stm32nucleo

Figure 2. X-NUCLEO-IDS01Ax plugged to STM32 Nucleo board

The interconnection between the STM32 Nucleo and the X-NUCLEO-IDS01Ax has been

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

been performed using the NUCLEO-L053R8 and NUCLEO-F401RE hosting the ultra-low

power STM32.

Getting started UM1872

6/21 DocID027622 Rev 2

2.2 System requirements

Using the Nucleo boards with the X-NUCLEO-IDS01Ax 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 and the wM-Bus graphical user interface utility on

the user's PC requires the following:

•128 MB of RAM

•Approximately 40 MB of hard disk space for the firmware

•Approximately 15 MB of hard disk space for the wM-Bus GUI

The use of the wM-Bus concentrator with the GUI requires additional boards to be

connected to the PC. The GUI can be used to check the wM-Bus communication example.

The Nucleo board acts as a meter and the STEVAL-IKR001Vx board connected to the PC

acts as a concentrator. Please note that the wM-Bus example is valid only for X-NUCLEO-

IDS01A4 (868 MHz version).

2.3 Setting up the board

Perform the following steps to set up the board:

1. Check that the jumper on the J1 connector is connected. This jumper provides the

required voltage to the devices on the board

2. Connect the X-NUCLEO-IDS01Ax to the Nucleo board from the top, as shown in

Figure 2.

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 on the Nucleo board

6. The evaluation kit is ready for use
