 Supported Features
 ==================

 The Zephyr STM32WB5MMG board configuration supports the following hardware features:

 +-----------+------------+-------------------------------------+
 | Interface | Controller | Driver/Component                    |
 +===========+============+=====================================+
 | UART      | on-chip    | serial port-polling;                |
 |           |            | serial port-interrupt               |
 +-----------+------------+-------------------------------------+
 | RADIO     | on-chip    | Bluetooth Low Energy                |
 +-----------+------------+-------------------------------------+


 Other hardware features are not yet supported on this Zephyr port.

 The default configuration can be found in the defconfig file:
 :zephyr_file:`boards/st/stm32wb5mmg/stm32wb5mmg_defconfig`

 Bluetooth and compatibility with STM32WB Copro Wireless Binaries
 ================================================================

 To operate bluetooth on STM32WB5MMG, Cortex-M0 core should be flashed with
 a valid STM32WB Coprocessor binaries (either 'Full stack' or 'HCI Layer').
 These binaries are delivered in STM32WB Cube packages, under
 Projects/STM32WB_Copro_Wireless_Binaries/STM32WB5x/
 For compatibility information with the various versions of these binaries,
 please check `modules/hal/stm32/lib/stm32wb/hci/README`_
 in the hal_stm32 repo.
 Note that since STM32WB Cube package V1.13.2, "full stack" binaries are not compatible
 anymore for a use in Zephyr and only "HCI Only" versions should be used on the M0
 side.

 Connections and IOs
 ===================


 Default Zephyr Peripheral Mapping:
 ----------------------------------

 .. rst-class:: rst-columns

 - UART_1 TX/RX : PB7/PB6
 - LPUART_1 TX/RX : PA3/PA2
 - USB : PA11/PA12
 - SWD : PA13/PA14

 System Clock
 ------------

 STM32WB5MMG System Clock could be driven by internal or external oscillator,
 as well as main PLL clock. By default System clock is driven by HSE clock at 32MHz.

 Serial Port
 -----------

 STM32WB5MMG board has 2 (LP)U(S)ARTs. LPUART1 is connected to the main U585I
 microcontroller that is used as HCI controller port. USART1 is not connected
 to any external pinout, so it is not possible to debug the module directly.
 Rather, users can use the available USB port (CN12) to run virtual com port
 (VCP) USB stack for the debugging.


 Programming and Debugging
 *************************

 Applications for the ``stm32wb5mmg`` board configuration can be built the
 usual way (see :ref:`build_an_application`).

 Flashing the module
 ===================

 The onboard ST-Link on the ``b_u585i_iot02a`` board can be used to flash the
 STM32WB5MMG module. To do this you should put SW4 on OFF and SW5 on ON mode.
 In this case the firmware will be uploaded on the STM32WB5MMG module.


 Flashing `hci_uart` application to STM32WB5MMG
 ----------------------------------------------

 Connect the B-U585I-IOT02A to your host computer using the USB port. Put
 the SW4 (MCU SWD) in OFF mode and SW5 (SWD BLE) in ON mode. Then build
 and flash an application. Here is an example for the
 :ref:`hci_uart <bluetooth-hci-uart-sample>` application.

 Run a serial host program to connect with your B-U585I-IOT02A board:

 .. code-block:: console

    $ minicom -D /dev/ttyACM0

 Then build and flash the application for the STM32WB5MMG module.

 .. zephyr-app-commands::
    :zephyr-app: samples/bluetooth/hci_uart
    :board: stm32wb5mmg
    :goals: build flash

 Next, reverse back the buttons to default mode (SW4 on ON and SW5
 on OFF) mode. In this case we will upload the Bluetooth sample on the
 main microcontroller.Then, build the bluetooth
 :zephyr_file:`samples/bluetooth/observer` demo application for
 B-U585I-IOT02A board:

 .. zephyr-app-commands::
    :zephyr-app: samples/bluetooth/observer
    :board: b_u585i_iot02a
    :goals: build flash

 Rest the board and you should see the following messages on the console:

 .. code-block:: console

    Starting Observer Demo
    Started scanning...
    Exiting main thread.
    Device found: 2C:98:F3:64:58:06 (random) (RSSI -82), type 3, AD data len 31
    Device found: CE:5B:9A:87:69:4F (random) (RSSI -80), type 3, AD data len 8
    Device found: 7B:1E:DD:38:23:E1 (random) (RSSI -85), type 0, AD data len 17


 Debugging
 =========

 You can debug an application in the usual way.  Here is an example for the
 :ref:`hci_uart <bluetooth-hci-uart-sample>` application.

 .. zephyr-app-commands::
    :zephyr-app: samples/bluetooth/observer
