X-NUCLEO-IDB05A1: BLE expansion board
|
|
#####################################
|

|
|
Overview
|
|
********
|
|
The X-NUCLEO-IDB05A1 is a Bluetooth Low Energy evaluation board based on the
|
|
SPBTLE-RF BlueNRG-MS RF module to allow expansion of the STM32 Nucleo boards.
|
|
The SPBTLE-RF module is FCC (FCC ID: S9NSPBTLERF) and IC certified
|
|
(IC: 8976C-SPBTLERF).
|
|
|
|
The X-NUCLEO-IDB05A1 is compatible with the ST Morpho and Arduino UNO R3
|
|
connector layout (the user can mount the ST Morpho connectors, if required). The
|
|
X-NUCLEO-IDB05A1 interfaces with the host microcontroller via the SPI pin, and
|
|
the user can change the default SPI clock, the SPI chip select and SPI IRQ by
|
|
changing one resistor on the evaluation board.
|
|
|
|
IMPORTANT NOTICE : This shield is not compatible out of the box with Arduino
|
|
UNO R3 connectors. Adaptation is required on most boards for compatibility.
|
|
Please refer to "Hardware configuration" section.

Hardware configuration
|
|
**********************
|
|
|
|
Out of the box, X-NUCLEO-IDB05A1 shield expect SPI SCK to be available on pin
|
|
D3 instead of usual Arduino UNO R3 SPI SCK D13.
|
|
Adaptation should be done on shield or board configuration to restore
|
|
compatibility. Shield configuration could be modified by moving resistors as
|
|
follows:
|
|
|
|
- SPI SCK: to use D13 instead of D3, remove R4 and add R6
|
|
|
|
Additionally, depending on your host board, some modifications of the BLE
|
|
expansion board could be made:
|
|
|
|
- CS: To use D10 instead of A1, remove R2 and add R7
|
|
- IRQ: To use D9 instead of A0, remove R1 and add R8
|
|
|
|
You could check Figure 3 in `X-NUCLEO-IDB05A1 databrief`_ for more details.
|
|
|
|
The stm32mp157c_dk2 board is known to need this IRQ pin modification.

X-NUCLEO-IDB05A1 provides a SPBTLE-RF chip with the following key features:
|
|
|
|
- Bluetooth Low Energy FCC and IC certified module based on Bluetooth ® SMART
|
|
4.1 network processor BlueNRG-MS
|
|
- Integrated Balun (BALF-NRG-01D3)
|
|

Programming
|
|
***********
|
|
|
|
You can use the X-NUCLEO-IDB05A1 as a Bluetooth Low-Energy controller
|
|
shield with an SPI host controller interface (HCI-SPI). Activate the presence
|
|
of the shield for the project build by adding the ``-DSHIELD`` arg to the
|
|
build command:
|
|
|
|
.. zephyr-app-commands::
|
|
:zephyr-app: your_app
|
|
:board: your_board_name
|
|
:shield: x_nucleo_idb05a1
|
|
:goals: build
|
|
|
|
Alternatively, set use of this shield in the project's ``CMakeLists.txt`` file:
|
|
|
|
.. code-block:: none
|
|
|
|
set(SHIELD x_nucleo_idb05a1)
