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

	a2dp	a2dp connection object.
[in]	ep	Local Audio Endpoint being configured.
[in]	codec_cfg	Codec configuration.
[out]	stream	Pointer to stream that will be configured for the endpoint.
[out]	rsp_err_code	give 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]	stream	Pointer to stream object.
[in]	rsp_err_code	the 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

a2dp	a2dp connection object.
err	error 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

a2dp	a2dp 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]	stream	Pointer to stream object.
[out]	rsp_err_code	give 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]	stream	Pointer to stream object.
[in]	rsp_err_code	the 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]	stream	Pointer to stream object.
[out]	rsp_err_code	give 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]	stream	Pointer to stream object.
[in]	rsp_err_code	the 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

The callback is called whenever an stream is requested to be released (release cmd and release the l2cap channel)

Parameters

Returns

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

release_rsp

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

Callback function for bt_a2dp_stream_release()

Called when the release operation is completed. (release cmd and release the l2cap channel)

Parameters

[in]	stream	Pointer to stream object.
