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
|
2017-06-13 05:30:03 +08:00
|
|
|
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
|
|
|
|
|
down.
|
|
|
|
|
|
|
|
|
|
.. 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
|
2017-08-09 14:21:11 +08:00
|
|
|
``bt-server-bredr`` Unix socket. When Bluetooth (CONFIG_BT) and Bluetooth
|
|
|
|
|
HCI UART driver (CONFIG_BT_H4) are enabled, the Bluetooth driver
|
2017-01-20 09:42:36 +08:00
|
|
|
registers with the system.
|
|
|
|
|
|
|
|
|
|
From now on Bluetooth may be used by the application. To run applications in
|
2017-06-13 05:30:03 +08:00
|
|
|
the QEMU emulation environment, type:
|

|

|
