Function Documentation

◆ bt_rfcomm_create_pdu()

struct net_buf * bt_rfcomm_create_pdu ( struct net_buf_pool pool)

#include <zephyr/bluetooth/rfcomm.h>

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

Parameters
poolWhich 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/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
connConnection object.
dlcDlc object.
channelServer 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/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
dlcDlc 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/rfcomm.h>

Send data to RFCOMM.

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

Parameters
dlcDlc object.
bufData 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/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
serverServer structure.
Returns
0 in case of success or negative value in case of error.
