Bluetooth H:4 UART driver. Requires hardware flow control
lines to be available.

Bluetooth three-wire (H:5) UART driver. Implementation of HCI
Three-Wire UART Transport Layer.
config BT_SPI
bool "SPI HCI"
select BT_RECV_IS_RX_THREAD
depends on 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.
config BT_NO_DRIVER
bool "No default HCI driver"
help
This is intended for unit tests where no internal driver
should be selected.

string "Device Name of UART Device for Bluetooth"
default "$(dt_str_val,DT_BT_UART_ON_DEV_NAME)" if HAS_DTS
default "UART_0"
depends on BT_UART
help
This option specifies the name of UART device to be used
for Bluetooth.

bool "Enable ACI message with with BlueNRG-based devices"
help
Enable support for devices compatible with the BlueNRG Bluetooth
Stack. Current driver supports: ST BLUENRG-MS.
config BT_SPI_BLUENRG
bool "Enable compatibility with BlueNRG-based devices"
help
Enable support for devices compatible with the BlueNRG Bluetooth
Stack. Current driver supports: ST BLUENRG-MS.
