BlueNRG-2 library does not work with the stock firmware that is loaded in the BLE
module of X-NUCLEO-BNRG2A1 expansion board.
For this reason:
•first of all, it is needed to solder on X-NUCLEO-BNRG2A1, if it is not soldered, a
0 Ohm resistor at R117.
•Then you can use a standard ST-Link V2-1 with 5 jumper wires female-female
together with STSW-BNRGFLASHER software tool (currently available only for
Windows PC) in order to update the firmware of the BLE module of X-NUCLEO-
BNRG2A1.
You need to connect the J12 pins of the X-NUCLEO-BNRG2A1 to the pins of the
ST-Link V2-1 as shown in the picture and follow the steps show in the next slide.
In particular we have the following connections:
J12 ST-Link V2-1
Pin 1 1
Pin 2 9
Pin 3 12
Pin 4 7
Pin 5 15

1. install the ST BlueNRG-1_2 Flasher Utility and open it,
then select the SWD tab
2. Erase the flash memory of the BlueNRG-2 chip
3. Download the Link Layer Only firmware for the BLE
module from the following link DTM_LLOnly.bin
4. Load the Link Layer Only firmware in the ST
BlueNRG-1_2 Flasher Utility and then press the
"Flash" button
5. If you need to restore the stock firmware of the BLE
module of X-NUCLEO-BNRG2A1, you can repeat the
procedure using this firmware image DTM_Full.bin
6. If you should find some issues during the update
process, you can try to repeat the procedure closing
the J15 jumper on the X-NUCLEO-BNRG2A1
expansion board.

FP-SNS-MOTENV1
Software Overview

Software Description
•FP-SNS-MOTENV1 is an STM32Cube function pack, which lets you connect your IoT node to a
smartphone via BLE and uses a suitable Android™ or iOS™ application, such as the ST BLE
Sensor app, to view real-time motion and environmental (such as temperature, relative humidity,
pressure) and sensor data.
•This package also enables advanced functions such as the sensor data fusion and accelerometer-
based real-time activity recognition, carry position, gesture recognition, motion intensity recognition
and real-time information about the number of steps and cadence which the user just performed
with the device, i.e. cell phone.
•Together with the suggested combination of STM32 and ST devices, it can be used to develop
specific wearable and environmental monitoring applications, or smart things applications in
general.
Key features
•Complete firmware to develop an IoT node with BLE connectivity, environmental and motion
sensors.
•Middleware libraries for sensor data fusion and acelerometer-based real-time activity recognition,
carry position, gesture recognition, motion intensity recognition and pedometer
•Compatible with ST BLE Sensor applications for Android/iOS, to perform sensor data reading,
motion algorithm features demo and firmware update (FOTA)
•Easy portability across different MCU families, thanks to the STM32Cube
•Free, user-friendly license terms Latest info available at www.st.com

1. How to install the pre-compiled binary:
•For each applications, there is inside the package one folder called “Binary”
➢For NUCLEO-F401RE and NUCLEO-L476RG:
•pre-compiled FP-SNS-MOTENV1 FW that could be flashed to a supported STM32 Nucleo (for X-NUCLEO-IKS01A2 and for X-NUCLEO-IKS01A3) using the ST-Link at
the right position (0x08004000)
oImportant Note: this pre-compiled binary is compatible with the FOTA update procedure
•pre-compiled FP-SNS-MOTENV1 + BootLoader FW that could be directly flashed to a supported STM32 Nucleo (for X-NUCLEO-IKS01A2 and for X-NUCLEO-IKS01A3)

2. How Install the code after compiling the project (excluding NUCLEO-L053R8) :
•Compile the project with your preferred IDE
•On Windows: for each IDE and for each platform there is one batch script:
•IAR toolchain Embedded Workbench V8.50.9:
•CleanMOTENV1_IAR_IKS01A2.bat
•CleanMOTENV1_IAR_IKS01A3.bat
•STM32CubeIDE Version 1.7.0:
•CleanMOTENV1_STM32CubeIDE_IKS01A2.bat
•CleanMOTENV1_STM32CubeIDE_IKS01A3.bat
•Keil µVision 5 toolchain - MDK-ARM Professional Version: 5.32.0:
•CleanMOTENV1_MDK-ARM_IKS01A2.bat
•CleanMOTENV1_MDK-ARM_IKS01A3.bat
•For Linux/iOS: only for STM32CubeIDE and for each platform there is one for STM32CubeProgrammer :
•CleanMOTENV1_STM32CubeIDE_IKS01A2.sh
•CleanMOTENV1_STM32CubeIDE_IKS01A3.sh
It’s necessary to edit this file for setting the right installation of the STM32CubeProgrammer
•These scripts perform the following steps:
•Full Flash Erase
•Flash the right BootLoader at the right position (0x08000000)
•Flash the MOTENV1 firmware at the right position (0x08004000)
➢This is the firmware that was compiled with the IDE
➢This firmware is compatible with the FOTA update procedure
•Save a complete Binary FW that includes both MOTENV1 and the BootLoader
➢This binary can be directly flashed to a supported STM32 board using the ST-Link or by doing “Drag & Drop”
➢Important Note: this additional pre-compiled binary is not compatible with the FOTA update procedure
