Function Documentation

bt_hci_close()

static int bt_hci_close ( const struct device * dev )

inlinestatic

#include <zephyr/drivers/bluetooth.h>

Close the HCI transport.

Closes the HCI transport. This function must not return until the transport is closed.

Parameters

dev	HCI device

Returns

0 on success or negative POSIX error number on failure.

bt_hci_open()

static int bt_hci_open ( const struct device * dev, bt_hci_recv_t recv )

inlinestatic

#include <zephyr/drivers/bluetooth.h>

Open the HCI transport.

Opens the HCI transport for operation. This function must not return until the transport is ready for operation, meaning it is safe to start calling the send() handler.

Parameters

dev	HCI device
recv	This is callback through which the HCI driver provides the host with data from the controller. The buffer passed to the callback will have its type set with bt_buf_set_type(). The callback is expected to be called from thread context.

Returns

0 on success or negative POSIX error number on failure.

bt_hci_send()

static int bt_hci_send ( const struct device * dev, struct net_buf * buf )

inlinestatic

#include <zephyr/drivers/bluetooth.h>

Send HCI buffer to controller.

Send an HCI packet to the controller. The packet type of the buffer must be set using bt_buf_set_type().

Note

This function must only be called from a cooperative thread.

Parameters

dev	HCI device
buf	Buffer containing data to be sent to the controller.

Returns

0 on success or negative POSIX error number on failure.

bt_hci_setup()

static int bt_hci_setup ( const struct device * dev, struct bt_hci_setup_params * params )

inlinestatic

#include <zephyr/drivers/bluetooth.h>

HCI vendor-specific setup.

Executes vendor-specific commands sequence to initialize BT Controller before BT Host executes Reset sequence. This is normally called directly after bt_hci_open().

Note

CONFIG_BT_HCI_SETUP must be selected for this field to be available.

Returns

0 on success or negative POSIX error number on failure.
