Detailed Description

Unicast Server callback structure.

Field Documentation

config

int(* bt_bap_unicast_server_cb::config) (struct bt_conn *conn, const struct bt_bap_ep *ep, enum bt_audio_dir dir, const struct bt_audio_codec_cfg *codec_cfg, struct bt_bap_stream **stream, struct bt_audio_codec_qos_pref *const pref, struct bt_bap_ascs_rsp *rsp)

Endpoint config request callback.

Config callback is called whenever an endpoint is requested to be configured

Parameters

[in]	conn	Connection object.
[in]	ep	Local Audio Endpoint being configured.
[in]	dir	Direction of the endpoint.
[in]	codec_cfg	Codec configuration.
[out]	stream	Pointer to stream that will be configured for the endpoint.
[out]	pref	Pointer to a QoS preference object that shall be populated with values. Invalid values will reject the codec configuration request.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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

disable

int(* bt_bap_unicast_server_cb::disable) (struct bt_bap_stream *stream, struct bt_bap_ascs_rsp *rsp)

Stream Disable request callback.

Disable callback is called whenever an Audio Stream is requested to disable the stream.

Parameters

[in]	stream	Stream object being disabled.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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

enable

int(* bt_bap_unicast_server_cb::enable) (struct bt_bap_stream *stream, const uint8_t meta[], size_t meta_len, struct bt_bap_ascs_rsp *rsp)

Stream Enable request callback.

Enable callback is called whenever an Audio Stream is requested to be enabled to stream.

Parameters

[in]	stream	Stream object being enabled.
[in]	meta	Metadata entries.
[in]	meta_len	Length of metadata.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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

metadata

int(* bt_bap_unicast_server_cb::metadata) (struct bt_bap_stream *stream, const uint8_t meta[], size_t meta_len, struct bt_bap_ascs_rsp *rsp)

Stream Metadata update request callback.

Metadata callback is called whenever an Audio Stream is requested to update its metadata.

Parameters

[in]	stream	Stream object.
[in]	meta	Metadata entries.
[in]	meta_len	Length of metadata.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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

qos

int(* bt_bap_unicast_server_cb::qos) (struct bt_bap_stream *stream, const struct bt_audio_codec_qos *qos, struct bt_bap_ascs_rsp *rsp)

Stream QoS request callback.

QoS callback is called whenever an Audio Stream Quality of Service needs to be configured.

Parameters

[in]	stream	Stream object being reconfigured.
[in]	qos	Quality of Service configuration.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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

reconfig

int(* bt_bap_unicast_server_cb::reconfig) (struct bt_bap_stream *stream, enum bt_audio_dir dir, const struct bt_audio_codec_cfg *codec_cfg, struct bt_audio_codec_qos_pref *const pref, struct bt_bap_ascs_rsp *rsp)

Stream reconfig request callback.

Reconfig callback is called whenever an Audio Stream needs to be reconfigured with different codec configuration.

Parameters

[in]	stream	Stream object being reconfigured.
[in]	dir	Direction of the endpoint.
[in]	codec_cfg	Codec configuration.
[out]	pref	Pointer to a QoS preference object that shall be populated with values. Invalid values will reject the codec configuration request.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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

release

int(* bt_bap_unicast_server_cb::release) (struct bt_bap_stream *stream, struct bt_bap_ascs_rsp *rsp)

Stream release callback.

Release callback is called whenever a new Audio Stream needs to be released and thus deallocated.

Parameters

[in]	stream	Stream object.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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

start

int(* bt_bap_unicast_server_cb::start) (struct bt_bap_stream *stream, struct bt_bap_ascs_rsp *rsp)

Stream Start request callback.

Start callback is called whenever an Audio Stream is requested to start streaming.

Parameters

[in]	stream	Stream object.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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

stop

int(* bt_bap_unicast_server_cb::stop) (struct bt_bap_stream *stream, struct bt_bap_ascs_rsp *rsp)

Stream Stop callback.

Stop callback is called whenever an Audio Stream is requested to stop streaming.

Parameters

[in]	stream	Stream object.
[out]	rsp	Object for the ASE operation response. Only used if the return value is non-zero.

Returns

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