Bluetooth subsystem
= Architecture =
All processing is done in fibers. Basic structure for packet processing
is bt_buf. Packets are queued to different queues and processed. Packet
allocation is done through a free packets queue which gets populated
during the initialization.
= Building =
Build host tools:
$ make -C host/src
Build samples
$ make -C samples/bluetooth/<app>
= Testing =
Host Bluetooth controler is connected to the second qemu serial line
through a UNIX socket (qemu option -serial unix:/tmp/bt-server-bredr).
On the host side BlueZ allows to "connect" Bluetooth controller through
a so-called user channel. Use the btproxy tool for that:
$ sudo tools/btproxy -u
Listening on /tmp/bt-server-bredr
Now qemu can connect serial line to the 'bt-server-bredr' UNIX socket
with following command:
For microkernel configuration run:
$ make microkernel.qemu
For nanokernel configuration run:
$ make nanokernel.qemu
Extra parameter to qemu might be added through QEMU_EXTRA_FLAGS.
There is smoke test application in nanokernel and microkernel test
directories which gets run in sanity check script:
$ scripts/sanity_chk/sanity_chk -T gcc [-B <BSP>]
For quick regression test use bt_regression, it only check Bluetooth test
$ samples/bluetooth/bt_regression.sh
