.. _bluetooth_setup:
To build any of the Bluetooth samples, follow the instructions below:
.. code-block:: console
$ make -C samples/bluetooth/<app>
Host Bluetooth controller is connected to the second QEMU serial line through a
Unix socket (QEMU option -serial unix:/tmp/bt-server-bredr). This option is
already added to QEMU through QEMU_EXTRA_FLAGS in Makefile.
On the host side BlueZ allows to "connect" Bluetooth controller through a
so-called user channel. Use the btproxy tool for that:
Note that before calling ``btproxy`` make sure that Bluetooth controller is
.. code-block:: console
$ sudo tools/btproxy -u
Listening on /tmp/bt-server-bredr
Running the application in QEMU will connect the second serial line to
``bt-server-bredr`` Unix socket. When Bluetooth (CONFIG_BT) and Bluetooth
HCI UART driver (CONFIG_BT_H4) are enabled, the Bluetooth driver
registers with the system.
From now on Bluetooth may be used by the application. To run applications in
the QEMU emulation environment, type:
.. code-block:: console
$ make run
.. toctree::
