 Mobile applications
 *******************

 It is often useful to make use of existing mobile applications to interact with
 hardware running Zephyr, to test functionality without having to write any
 additional code or requiring extra hardware.

 The recommended mobile applications for interacting with Zephyr are:

 * Android:

   * `nRF Connect for Android`_
   * `nRF Mesh for Android`_
   * `LightBlue for Android`_

 * iOS:

   * `nRF Connect for iOS`_
   * `nRF Mesh for iOS`_
   * `LightBlue for iOS`_

 .. _bluetooth_bluez:

 Using BlueZ with Zephyr
 ***********************

 The Linux Bluetooth Protocol Stack, BlueZ, comes with a very useful set of
 tools that can be used to debug and interact with Zephyr's Bluetooth Host and
 Controller. In order to benefit from these tools you will need to make sure
 that you are running a recent version of the Linux Kernel and BlueZ:

 * Linux Kernel 4.10+
 * BlueZ 4.45+

 Additionally, some of the BlueZ tools might not be bundled by default by your
 Linux distribution. If you need to build BlueZ from scratch to update to a
 recent version or to obtain all of its tools you can follow the steps below:

 .. code-block:: console

    git clone git://git.kernel.org/pub/scm/bluetooth/bluez.git
    cd bluez
    ./bootstrap-configure --disable-android --disable-midi
    make

 You can then find :file:`btattach`, :file:`btmgt` and :file:`btproxy` in the
 :file:`tools/` folder and :file:`btmon` in the :file:`monitor/` folder.

 You'll need to enable BlueZ's experimental features so you can access its
 most recent Bluetooth functionality. Do this by editing the file
 :file:`/lib/systemd/system/bluetooth.service`
 and making sure to include the :literal:`-E` option in the daemon's execution
 start line:

 .. code-block:: console

    ExecStart=/usr/libexec/bluetooth/bluetoothd -E

 Finally, reload and restart the daemon:

 .. code-block:: console

    sudo systemctl daemon-reload
    sudo systemctl restart bluetooth

 .. _bluetooth_qemu_native:

 Running on QEMU or native_sim
 *****************************

 It's possible to run Bluetooth applications using either the :ref:`QEMU
 emulator<application_run_qemu>` or :zephyr:board:`native_sim <native_sim>`.

 In either case, a Bluetooth controller needs to be exported from
 the host OS (Linux) to the emulator. For this purpose you will need some tools
 described in the :ref:`bluetooth_bluez` section.

 Using the Host System Bluetooth Controller
 ==========================================

 The host OS's Bluetooth controller is connected in the following manner:

 * To the second QEMU serial line using a UNIX socket. This socket gets used
   with the help of the QEMU option :literal:`-serial unix:/tmp/bt-server-bredr`.
   This option gets passed to QEMU through :makevar:`QEMU_EXTRA_FLAGS`
   automatically whenever an application has enabled Bluetooth support.
 * To :ref:`native_sim's BT User Channel driver <nsim_bt_host_cont>` through the use of a
   command-line option passed to the native_sim executable: ``--bt-dev=hci0``

 On the host side, BlueZ allows you to export its Bluetooth controller
 through a so-called user channel for QEMU and :zephyr:board:`native_sim <native_sim>` to use.

 .. note::
    You only need to run ``btproxy`` when using QEMU. native_sim handles
    the UNIX socket proxying automatically

 If you are using QEMU, in order to make the Controller available you will need
 one additional step using ``btproxy``:

 #. Make sure that the Bluetooth controller is down

 #. Use the btproxy tool to open the listening UNIX socket, type:

    .. code-block:: console

       sudo tools/btproxy -u -i 0
       Listening on /tmp/bt-server-bredr

    You might need to replace :literal:`-i 0` with the index of the Controller
    you wish to proxy.

    If you see ``Received unknown host packet type 0x00`` when running QEMU, then
    add :literal:`-z` to the ``btproxy`` command line to ignore any null bytes
    transmitted at startup.

 Once the hardware is connected and ready to use, you can then proceed to
 building and running a sample:

 * Choose one of the Bluetooth sample applications located in
   :literal:`samples/bluetooth`.

 * To run a Bluetooth application in QEMU, type:

   .. zephyr-app-commands::
      :zephyr-app: samples/bluetooth/<sample>
      :host-os: unix
      :board: qemu_x86
      :goals: run
      :compact:

   Running QEMU now results in a connection with the second serial line to
   the :literal:`bt-server-bredr` UNIX socket, letting the application
   access the Bluetooth controller.

 * To run a Bluetooth application in :zephyr:board:`native_sim <native_sim>`, first build it:

   .. zephyr-app-commands::
      :zephyr-app: samples/bluetooth/<sample>
      :host-os: unix
      :board: native_sim
      :goals: build
      :compact:

   And then run it with::

      $ sudo ./build/zephyr/zephyr.exe --bt-dev=hci0

 Using a Zephyr-based Bluetooth Controller
 =========================================

 Depending on which hardware you have available, you can choose between two
 transports when building a single-mode, Zephyr-based Bluetooth Controller:

 * UART: Use the :zephyr:code-sample:`bluetooth_hci_uart` sample and follow
   the instructions in :ref:`bluetooth-hci-uart-qemu-posix`.
 * USB: Use the :zephyr:code-sample:`bluetooth_hci_usb` sample and then
   treat it as a Host System Bluetooth Controller (see previous section)

 .. _bluetooth-hci-tracing:

 HCI Tracing
 ===========

 When running the Host on a computer connected to an external Controller, it
 is very useful to be able to see the full log of exchanges between the two,
 in the format of a :ref:`bluetooth-hci` log.
 In order to see those logs, you can use the built-in ``btmon`` tool from BlueZ:

 .. code-block:: console

    $ btmon

 The output looks like this::

    = New Index: 00:00:00:00:00:00 (Primary,Virtual,Control)                     0.274200
    = Open Index: 00:00:00:00:00:00                                              0.274500
    < HCI Command: Reset (0x03|0x0003) plen 0                                 #1 0.274600
    > HCI Event: Command Complete (0x0e) plen 4                               #2 0.274700
          Reset (0x03|0x0003) ncmd 1
          Status: Success (0x00)
    < HCI Command: Read Local Supported Features (0x04|0x0003) plen 0         #3 0.274800
    > HCI Event: Command Complete (0x0e) plen 12                              #4 0.274900
          Read Local Supported Features (0x04|0x0003) ncmd 1
          Status: Success (0x00)
          Features: 0x00 0x00 0x00 0x00 0x60 0x00 0x00 0x00
             BR/EDR Not Supported
             LE Supported (Controller)

 .. _bluetooth-embedded-hci-tracing:

 Embedded HCI tracing
 --------------------

 When running both Host and Controller in actual Integrated Circuits, you will
 only see normal log messages on the console by default, without any way of
 accessing the HCI traffic between the Host and the Controller.  However, there
 is a special Bluetooth logging mode that converts the console to use a binary
 protocol that interleaves both normal log messages as well as the HCI traffic.

 Set the following Kconfig options to enable this protocol before building your
 application:

 .. code-block:: cfg

    CONFIG_BT_DEBUG_MONITOR_UART=y
    CONFIG_UART_CONSOLE=n

 - Setting :kconfig:option:`CONFIG_BT_DEBUG_MONITOR_UART` activates the formatting
 - Clearing :kconfig:option:`CONFIG_UART_CONSOLE` makes the UART unavailable for
   the system console. E.g. for ``printk`` and the :kconfig:option:`boot banner
   <CONFIG_BOOT_BANNER>`

 To decode the binary protocol that will now be sent to the console UART you need
 to use the btmon tool from :ref:`BlueZ <bluetooth_bluez>`:

 .. code-block:: console

    $ btmon --tty <console TTY> --tty-speed 115200

 If UART is not available (or you still want non-binary logs), you can set
 :kconfig:option:`CONFIG_BT_DEBUG_MONITOR_RTT` instead, which will use Segger
 RTT. For example, if trying to connect to a nRF52840DK with S/N 683578642:

 .. code-block:: console

    $ btmon --jlink nRF52840_xxAA,683578642

 .. _bluetooth_virtual_posix:

 Running on a Virtual Controller and native_sim
 **********************************************

 An alternative to a Bluetooth physical controller is the use of a virtual
 controller. This controller can be connected over an HCI TCP server.
 This TCP server must support the HCI H4 protocol. In comparison to the physical controller
 variant, the virtual controller allows to test a Zephyr application running on the native
 boards without a physical Bluetooth controller.

 The main use case for a virtual controller is to do Bluetooth connectivity tests without
 the need of Bluetooth hardware. This allows to automate Bluetooth integration tests with
 external applications such as a Bluetooth gateway or a mobile application.

 To demonstrate this functionality an example is given to interact with a virtual controller.
 For this purpose, the experimental python module `Bumble`_ from Google is used as it allows to create
 a TCP Bluetooth virtual controller and connect with the Zephyr Bluetooth host. To install
 bumble follow the `Bumble Getting Started Guide`_.

 .. note::
    If your Zephyr application requires the use of the HCI LE Set extended commands, install
    the branch ``controller-extended-advertising`` from Bumble.

 Android Emulator
 =================

 You can test the virtual controller by connecting a Bluetooth Zephyr application
 to the `Android Emulator`_.

 To connect your application to the Android Emulator follow the next steps:

     #. Build your Zephyr application and disable the HCI ACL flow
        control (i.e. ``CONFIG_BT_HCI_ACL_FLOW_CONTROL=n``) as the
        virtual controller from android does not support it at the moment.

     #. Install Android Emulator version >= 33.1.4.0. The easiest way to do this is by installing
        the latest `Android Studio Preview`_ version.

     #. Create a new Android Virtual Device (AVD) with the `Android Device Manager`_. The AVD should use at least SDK API 34.

     #. Run the Android Emulator via terminal as follows:

        ``emulator avd YOUR_AVD -packet-streamer-endpoint default``

     #. Create a Bluetooth bridge between the Zephyr application and
        the virtual controller from Android Emulator with the `Bumble`_ utility ``hci-bridge``.

        ``bumble-hci-bridge tcp-server:_:1234 android-netsim``

        This command will create a TCP server bridge on the local host IP address ``127.0.0.1``
        and port number ``1234``.

     #. Run the Zephyr application and connect to the TCP server created in the last step.

        ``./zephyr.exe --bt-dev=127.0.0.1:1234``

 After following these steps the Zephyr application will be available to the Android Emulator
 over the virtual Bluetooth controller that was bridged with Bumble. You can verify that the
 Zephyr application can communicate over Bluetooth by opening the Bluetooth settings in your
 AVD and scanning for your Zephyr application device. To test this you can build the Bluetooth
 peripheral samples such as :zephyr:code-sample:`ble_peripheral_hr` or
 :zephyr:code-sample:`ble_peripheral_dis`.

 .. _bluetooth_ctlr_bluez:

 Using Zephyr-based Controllers with BlueZ
 *****************************************

 If you want to test a Zephyr-powered Bluetooth Controller using BlueZ's Bluetooth
 Host, you will need a few tools described in the :ref:`bluetooth_bluez` section.
 Once you have installed the tools you can then use them to interact with your
 Zephyr-based controller:

    .. code-block:: console

       sudo tools/btmgmt --index 0
       [hci0]# auto-power
       [hci0]# find -l

 You might need to replace :literal:`--index 0` with the index of the Controller
 you wish to manage.
 Additional information about :file:`btmgmt` can be found in its manual pages.
