config BT_H4

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

config BT_H5
	bool "H:5 UART [EXPERIMENTAL]"
	select UART_INTERRUPT_DRIVEN
	select BT_UART
	depends on SERIAL
	help
	  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.

config BT_UART_ON_DEV_NAME
	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.

config BT_BLUENRG_ACI
	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.
