59Other hardware features are not yet supported on this Zephyr port.
60
61The default configuration can be found in the defconfig file:
62:zephyr_file:`boards/st/nucleo_wb09ke/nucleo_wb09ke_defconfig`
63
64Bluetooh support
65----------------
66
67BLE support is enabled; however, to build a Zephyr sample using this board,
68you first need to fetch the Bluetooth controller library into Zephyr as a binary BLOB.
69
70To fetch binary BLOBs:
71
72.. code-block:: console
73
74   west blobs fetch hal_stm32
75
76Connections and IOs

81
82- USART1 TX/RX       : PA1/PB0 (ST-Link Virtual COM Port)
83- BUTTON (B1)        : PA0
84- BUTTON (B2)        : PB5
85- BUTTON (B3)        : PB14
86- LED (LD1/BLUE)     : PB1
87- LED (LD2/GREEN)    : PB4
88- LED (LD3/RED)      : PB2

92Programming and Debugging
93*************************
94
95Nucleo WB09KE board includes an ST-LINK-V3EC embedded debug tool interface.
96
97Applications for the ``nucleo_w09ke`` board target can be built and flashed
98in the usual way (see :ref:`build_an_application` and :ref:`application_run`
99for more details).
100
101Flashing
102========
103
104The board is configured to be flashed using the west `STM32CubeProgrammer`_ runner,
105so :ref:`it must be installed <stm32cubeprog-flash-host-tools>` beforehand.
106
107Alternatively, OpenOCD can also be used to flash the board using the
108``--runner`` (or ``-r``) option:
109
110.. code-block:: console
111
112   $ west flash --runner openocd
113
114Flashing an application to Nucleo WB09KE
115----------------------------------------
116
117Connect the Nucleo WB09KE to your host computer using the USB port,
118then run a serial host program to connect with your Nucleo board:
119
120.. code-block:: console
121
122   $ minicom -D /dev/ttyACM0
123
124Now build and flash an application. Here is an example for
125:zephyr:code-sample:`hello_world`.
126
127.. zephyr-app-commands::
128   :zephyr-app: samples/hello_world
129   :board: nucleo_wb09ke
130   :goals: build flash
131
132You should see the following message on the console:
133
134.. code-block:: console
135
136   Hello World! nucleo_wb09ke/stm32wb09
137
138
139Debugging
140=========
141
142You can debug an application in the usual way.  Here is an example for the
143:zephyr:code-sample:`hello_world` application.
144
145.. zephyr-app-commands::
146   :zephyr-app: samples/hello_world
147   :board: nucleo_wb09ke
148   :maybe-skip-config:
149   :goals: debug
