X-NUCLEO-IKS4A1 Hardware Description (2/2)
Bluetooth Low Energy Expansion Board
Hardware Description
- The X-NUCLEO-BNRG2A1 is a Bluetooth Low Energy (BLE) evaluation and development board system, designed around ST’s BLUENRG-M2SP Bluetooth Low Energy module based on BlueNRG-2.
- The BlueNRG-2 processor hosted in the BLUENRG-M2SP module communicates with the STM32 microcontroller, hosted on the Nucleo development board, through an SPI link available on the Arduino UNO R3 connector.
Key Product on board
- BLUENRG-M2SP Bluetooth Low Energy, FCC and IC certified (FCC ID: S9NBNRGM2SP, IC: B976C-BNRGM2SP), module based on Bluetooth® Low Energy wireless network processor BlueNRG-2, BLE v5.0 compliant.
- BLUENRG-M2SP integrates a BALF-NRG-02D3 balun and a PCB antenna. It embeds 32 MHz crystal oscillator for the BlueNRG-2.
- M95640-RMC6TG 64-Kbit serial SPI bus EEPROM with high-speed clock interface
Important Hardware Additional Information
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 |

- For NUCLEO-U575ZI-Q, after the boot the MOTENV1 firmware receives the new firmware from the STBLESensor application, saves it on one memory bank (either bank1 or bank2) and performs a reboot executing the new code saved on the other memory bank. A program related to a specific region can run in that region only. The MOTENV1 application, however, can swap among different flash banks and each program can run in any flash memory bank.
