Bluetooth H:4 UART driver. Requires hardware flow control
lines to be available.
config BT_H5
bool "H:5 UART [EXPERIMENTAL]"
select BT_UART

help
Bluetooth three-wire (H:5) UART driver. Implementation of HCI
Three-Wire UART Transport Layer.
config BT_RPMSG

help
Bluetooth HCI driver for communication with another CPU
using RPMsg framework.
config BT_SPI
bool "SPI HCI"
select SPI
help
Supports Bluetooth ICs using SPI as the communication protocol.
HCI packets are sent and received as single Byte transfers,
prepended after a known header. Headers may vary per device, so
additional platform specific knowledge may need to be added as
devices are.

config BT_USERCHAN
bool "HCI User Channel based driver"
depends on BOARD_NATIVE_POSIX
help
This driver provides access to the local Linux host's Bluetooth
adapter using a User Channel HCI socket to the Linux kernel. It
is only intended to be used with the native POSIX build of Zephyr.
The Bluetooth adapter must be powered off in order for Zephyr to
be able to use it.

help
PSOC6 BLESS driver with BLE Controller which operates in
Single CPU mode.
config BT_NO_DRIVER
bool "No default HCI driver"
select BT_HAS_HCI_VS
help
This is intended for unit tests where no internal driver
should be selected.

Enable the quirk wherein BT Host stack will auto-initiate Data Length
Update procedure for new connections for controllers that do not
auto-initiate the procedure if the default data length parameters are
not equal to the initial parameters.
This has to be enabled when the BLE controller connected is Zephyr
open source controller.
config BT_HCI_SETUP
bool
help
Enable the HCI vendor-specific Setup function.
This option has to be enabled when the BT Controller requires execution
of the vendor-specific commands sequence to initialize the BT Controller
before the BT Host executes a Reset sequence.
The user should generally avoid changing it via menuconfig or in
configuration files. This option are enabled by the vendor-specific
HCI extension, where the Setup function is implemented.
