Field Documentation

◆ config_req

int(* bt_a2dp_cb::config_req) (struct bt_a2dp *a2dp, struct bt_a2dp_ep *ep, struct bt_a2dp_codec_cfg *codec_cfg, struct bt_a2dp_stream **stream, uint8_t *rsp_err_code)

Endpoint config request callback.

The callback is called whenever an endpoint is requested to be configured.

Parameters
a2dpa2dp connection object.
[in]epLocal Audio Endpoint being configured.
[in]codec_cfgCodec configuration.
[out]streamPointer to stream that will be configured for the endpoint.
[out]rsp_err_codegive the error code if response error. bt_a2dp_err_code or bt_avdtp_err_code
Returns
0 in case of success or negative value in case of error.

◆ config_rsp

void(* bt_a2dp_cb::config_rsp) (struct bt_a2dp_stream *stream, uint8_t rsp_err_code)

Callback function for bt_a2dp_stream_config()

Called when the codec configure operation is completed.

Parameters
[in]streamPointer to stream object.
[in]rsp_err_codethe remote responded error code bt_a2dp_err_code or bt_avdtp_err_code

◆ connected

void(* bt_a2dp_cb::connected) (struct bt_a2dp *a2dp, int err)

A a2dp connection has been established.

This callback notifies the application of a a2dp connection. It means the AVDTP L2CAP connection. In case the err parameter is non-zero it means that the connection establishment failed.

Parameters
a2dpa2dp connection object.
errerror code.

◆ disconnected

void(* bt_a2dp_cb::disconnected) (struct bt_a2dp *a2dp)

A a2dp connection has been disconnected.

This callback notifies the application that a a2dp connection has been disconnected.

Parameters
a2dpa2dp connection object.

◆ establish_req

int(* bt_a2dp_cb::establish_req) (struct bt_a2dp_stream *stream, uint8_t *rsp_err_code)

stream establishment request callback

The callback is called whenever an stream is requested to be established (open cmd and create the stream l2cap channel).

Parameters
[in]streamPointer to stream object.
[out]rsp_err_codegive the error code if response error. bt_a2dp_err_code or bt_avdtp_err_code
Returns
0 in case of success or negative value in case of error.

◆ establish_rsp

void(* bt_a2dp_cb::establish_rsp) (struct bt_a2dp_stream *stream, uint8_t rsp_err_code)

Callback function for bt_a2dp_stream_establish()

Called when the establishment operation is completed. (open cmd and create the stream l2cap channel).

Parameters
[in]streamPointer to stream object.
[in]rsp_err_codethe remote responded error code bt_a2dp_err_code or bt_avdtp_err_code

◆ reconfig_req

int(* bt_a2dp_cb::reconfig_req) (struct bt_a2dp_stream *stream, uint8_t *rsp_err_code)

Endpoint config request callback.

The callback is called whenever an endpoint is requested to be reconfigured.

Parameters
[in]streamPointer to stream object.
[out]rsp_err_codegive the error code if response error. bt_a2dp_err_code or bt_avdtp_err_code
Returns
0 in case of success or negative value in case of error.

◆ reconfig_rsp

void(* bt_a2dp_cb::reconfig_rsp) (struct bt_a2dp_stream *stream, uint8_t rsp_err_code)

Callback function for bt_a2dp_stream_reconfig()

Called when the reconfig operation is completed.

Parameters
[in]streamPointer to stream object.
[in]rsp_err_codethe remote responded error code bt_a2dp_err_code or bt_avdtp_err_code

◆ release_req

int(* bt_a2dp_cb::release_req) (struct bt_a2dp_stream *stream, uint8_t *rsp_err_code)

stream release request callback
