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.

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.

this device is used to reply back with HCI frames that are sent over
