Supported Features

.. zephyr:board-supported-hw::

Bluetooth® support

Bluetooth® Low Energy support is enabled; however, to build a Zephyr sample using this board, you first need to fetch the Bluetooth® controller library into Zephyr as a binary BLOB.

To fetch binary BLOBs:

.. code-block:: console

west blobs fetch hal_stm32

Connections and IOs

Default Zephyr Peripheral Mapping:

USART1 TX/RX : PA9/PA8 (ST-Link Virtual COM Port)
BUTTON (B1) : PA0
BUTTON (B2) : PB5
BUTTON (B3) : PB9
LED (LD1/BLUE) : PB0
LED (LD2/GREEN) : PB4
LED (LD3/RED) : PB2

For more details, please refer to the Nucleo WB07CC board User Manual_.

Programming and Debugging

.. zephyr:board-supported-runners::

Nucleo WB07CC board includes an ST-LINK-V3EC embedded debug tool interface.

Applications for the nucleo_wb07cc board target can be built and flashed in the usual way (see :ref:build_an_application and :ref:application_run for more details).

Flashing

The board is configured to be flashed using the west STM32CubeProgrammer_ runner, so :ref:it must be installed <stm32cubeprog-flash-host-tools> beforehand.

Alternatively, OpenOCD can also be used to flash the board using the --runner (or -r) option:

.. code-block:: console

$ west flash --runner openocd

Flashing an application to Nucleo WB07CC

Connect the Nucleo WB07CC to your host computer using the USB port, then run a serial host program to connect with your Nucleo board:

.. code-block:: console

$ minicom -D /dev/ttyACM0

Now build and flash an application. Here is an example for :zephyr:code-sample:hello_world.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: nucleo_wb07cc :goals: build flash

You should see the following message on the console:

.. code-block:: console

Hello World! nucleo_wb07cc/stm32wb07

Usage of the pyOCD runner requires installation of an additional target pack. This can be done using the following commands:

.. code-block:: console

$ pyocd pack update $ pyocd pack install stm32wb0

Debugging

You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: nucleo_wb07cc :maybe-skip-config: :goals: debug
