Function Documentation

bt_rfcomm_create_pdu()

struct net_buf * bt_rfcomm_create_pdu

(

struct net_buf_pool *

pool

)

#include <zephyr/bluetooth/classic/rfcomm.h>

Allocate the buffer from pool after reserving head room for RFCOMM, L2CAP and ACL headers.

Parameters

pool	Which pool to take the buffer from.

Returns

New buffer.

bt_rfcomm_dlc_connect()

int bt_rfcomm_dlc_connect	(	struct bt_conn *	conn,
		struct bt_rfcomm_dlc *	dlc,
		uint8_t	channel
	)

#include <zephyr/bluetooth/classic/rfcomm.h>

Connect RFCOMM channel.

Connect RFCOMM dlc by channel, once the connection is completed dlc connected() callback will be called. If the connection is rejected disconnected() callback is called instead.

Parameters

conn	Connection object.
dlc	Dlc object.
channel	Server channel to connect to.

Returns

0 in case of success or negative value in case of error.

bt_rfcomm_dlc_disconnect()

int bt_rfcomm_dlc_disconnect

(

struct bt_rfcomm_dlc *

dlc

)

#include <zephyr/bluetooth/classic/rfcomm.h>

Disconnect RFCOMM dlc.

Disconnect RFCOMM dlc, if the connection is pending it will be canceled and as a result the dlc disconnected() callback is called.

Parameters

dlc	Dlc object.

Returns

0 in case of success or negative value in case of error.

bt_rfcomm_dlc_send()

int bt_rfcomm_dlc_send	(	struct bt_rfcomm_dlc *	dlc,
		struct net_buf *	buf
	)

#include <zephyr/bluetooth/classic/rfcomm.h>

Send data to RFCOMM.

Send data from buffer to the dlc. Length should be less than or equal to mtu.

Parameters

dlc	Dlc object.
buf	Data buffer.

Returns

Bytes sent in case of success or negative value in case of error.

bt_rfcomm_server_register()

int bt_rfcomm_server_register

(

struct bt_rfcomm_server *

server

)

#include <zephyr/bluetooth/classic/rfcomm.h>

Register RFCOMM server.

Register RFCOMM server for a channel, each new connection is authorized using the accept() callback which in case of success shall allocate the dlc structure to be used by the new connection.

Parameters

server

Server structure.

Returns

0 in case of success or negative value in case of error.
