The default configuration can be found in the defconfig file: boards/st/nucleo_wb09ke/nucleo_wb09ke_defconfig

Bluetooh support

BLE 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:

west blobs fetch hal_stm32

Connections and IOs

Default Zephyr Peripheral Mapping:

  • USART1 TX/RX : PA1/PB0 (ST-Link Virtual COM Port)

  • BUTTON (B1) : PA0

  • BUTTON (B2) : PB5

  • BUTTON (B3) : PB14

  • LED (LD1/BLUE) : PB1

  • LED (LD2/GREEN) : PB4

  • LED (LD3/RED) : PB2

For more details, please refer to the Nucleo WB09KE board User Manual.

Programming and Debugging

Nucleo WB09KE board includes an ST-LINK-V3EC embedded debug tool interface.

Applications for the nucleo_w09ke board target can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

Flashing

The board is configured to be flashed using the west STM32CubeProgrammer runner, so it must be installed beforehand.

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

$ west flash --runner openocd

Flashing an application to Nucleo WB09KE

Connect the Nucleo WB09KE to your host computer using the USB port, then run a serial host program to connect with your Nucleo board:

$ minicom -D /dev/ttyACM0

Now build and flash an application. Here is an example for Hello World.

# From the root of the zephyr repository
west build -b nucleo_wb09ke samples/hello_world
west flash

You should see the following message on the console:

Hello World! nucleo_wb09ke/stm32wb09

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b nucleo_wb09ke samples/hello_world
west debug
