Detailed Description

Typedef Documentation

bt_bap_ep_func_t

typedef void(* bt_bap_ep_func_t) (struct bt_bap_ep *ep, void *user_data)

#include <zephyr/bluetooth/audio/bap.h>

The callback function called for each endpoint.

Parameters

ep	The structure object with endpoint info.
user_data	Data to pass to the function.

Function Documentation

bt_bap_unicast_server_config_ase()

int bt_bap_unicast_server_config_ase	(	struct bt_conn *	conn,
		struct bt_bap_stream *	stream,
		struct bt_audio_codec_cfg *	codec_cfg,
		const struct bt_audio_codec_qos_pref *	qos_pref )

#include <zephyr/bluetooth/audio/bap.h>

Initialize and configure a new ASE.

Parameters

conn	Connection object
stream	Configured stream object to be attached to the ASE
codec_cfg	Codec configuration
qos_pref	Audio Stream Quality of Service Preference

Returns

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

bt_bap_unicast_server_foreach_ep()

void bt_bap_unicast_server_foreach_ep	(	struct bt_conn *	conn,
		bt_bap_ep_func_t	func,
		void *	user_data )

#include <zephyr/bluetooth/audio/bap.h>

Iterate through all endpoints of the given connection.

Parameters

conn	Connection object
func	Function to call for each endpoint.
user_data	Data to pass to the callback function.

bt_bap_unicast_server_register()

int bt_bap_unicast_server_register

(

const struct bt_bap_unicast_server_register_param *

param

)

#include <zephyr/bluetooth/audio/bap.h>

Register the Unicast Server.

Register the Unicast Server. Only a single Unicast Server can be registered at any one time. This will register ASCS in the GATT database.

Parameters

param

Registration parameters for ascs.

Returns

0 in case of success, negative error code otherwise.

bt_bap_unicast_server_register_cb()

int bt_bap_unicast_server_register_cb

(

const struct bt_bap_unicast_server_cb *

cb

)

#include <zephyr/bluetooth/audio/bap.h>

Register unicast server callbacks.

Only one callback structure can be registered, and attempting to registering more than one will result in an error. Prior to calling this function the Unicast Server needs to be registered with bt_bap_unicast_server_register().

Parameters

cb	Unicast server callback structure.

Returns

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

bt_bap_unicast_server_unregister()

int bt_bap_unicast_server_unregister

(

void

)

#include <zephyr/bluetooth/audio/bap.h>

Unregister the Unicast Server.

Unregister the Unicast Server. This will unregister ASCS in the GATT database. Before calling this function, any callbacks registered through bt_bap_unicast_server_register_cb() needs to be unregistered with bt_bap_unicast_server_unregister_cb().

Calling this function will issue an release operation on any ASE in a non-idle state.

Returns

0 in case of success, negative error code otherwise.

bt_bap_unicast_server_unregister_cb()

int bt_bap_unicast_server_unregister_cb

(

const struct bt_bap_unicast_server_cb *

cb

)

#include <zephyr/bluetooth/audio/bap.h>

Unregister unicast server callbacks.

May only unregister a callback structure that has previously been registered by bt_bap_unicast_server_register_cb().

Calling this function will issue an release operation on any ASE in a non-idle state.

Parameters

cb	Unicast server callback structure.

Returns

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