Macro Definition Documentation

BT_HCI_ERR_EXT_HANDLED

#define BT_HCI_ERR_EXT_HANDLED   0xff

#include <zephyr/bluetooth/hci_raw.h>

BT_HCI_RAW_CMD_EXT

#define BT_HCI_RAW_CMD_EXT	(		_op,
			_min_len,
			_func
	)

#include <zephyr/bluetooth/hci_raw.h>

Value:

        { \
                .op = _op, \
                .min_len = _min_len, \
                .func = _func, \
        }

Helper macro to define a command extension.

Parameters

_op	Opcode of the command.
_min_len	Minimal length of the command.
_func	Handler function to be called.

Enumeration Type Documentation

anonymous enum

anonymous enum

#include <zephyr/bluetooth/hci_raw.h>

Enumerator
BT_HCI_RAW_MODE_PASSTHROUGH	Passthrough mode. While in this mode the buffers are passed as is between the stack and the driver.
BT_HCI_RAW_MODE_H4	H:4 mode. While in this mode H:4 headers will added into the buffers according to the buffer type when coming from the stack and will be removed and used to set the buffer type.

Function Documentation

bt_enable_raw()

int bt_enable_raw

(

struct k_fifo *

rx_queue

)

#include <zephyr/bluetooth/hci_raw.h>

Enable Bluetooth RAW channel:

Enable Bluetooth RAW HCI channel.

Parameters

rx_queue

netbuf queue where HCI packets received from the Bluetooth controller are to be queued. The queue is defined in the caller while the available buffers pools are handled in the stack.

Returns

Zero on success or (negative) error code otherwise.

bt_hci_raw_cmd_ext_register()

void bt_hci_raw_cmd_ext_register	(	struct bt_hci_raw_cmd_ext *	cmds,
		size_t	size
	)

#include <zephyr/bluetooth/hci_raw.h>

Register Bluetooth RAW command extension table.

Register Bluetooth RAW channel command extension table, opcodes in this table are intercepted to sent to the handler function.

Parameters

cmds	Pointer to the command extension table.
size	Size of the command extension table.

bt_hci_raw_get_mode()

uint8_t bt_hci_raw_get_mode

(

void

)

#include <zephyr/bluetooth/hci_raw.h>

Get Bluetooth RAW channel mode.

Get access mode of Bluetooth RAW channel.

Returns

Access mode.

bt_hci_raw_set_mode()

int bt_hci_raw_set_mode

(

uint8_t

mode

)

#include <zephyr/bluetooth/hci_raw.h>

Set Bluetooth RAW channel mode.

Set access mode of Bluetooth RAW channel.

Parameters

mode	Access mode.

Returns

Zero on success or (negative) error code otherwise.

bt_send()

int bt_send

(

struct net_buf *

buf

)

#include <zephyr/bluetooth/hci_raw.h>

Send packet to the Bluetooth controller.

Send packet to the Bluetooth controller. Caller needs to implement netbuf pool.

Parameters

buf	netbuf packet to be send

Returns

Zero on success or (negative) error code otherwise.
