| 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. |

| 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. |

| bool "No default HCI driver" |
| help |
| This is intended for unit tests where no internal driver |
| should be selected. |
