Field Documentation

unicast_discovery_complete

void(* bt_cap_initiator_cb::unicast_discovery_complete) (struct bt_conn *conn, int err, const struct bt_csip_set_coordinator_set_member *member, const struct bt_csip_set_coordinator_csis_inst *csis_inst)

Callback for bt_cap_initiator_unicast_discover().

Parameters

conn	The connection pointer supplied to bt_cap_initiator_unicast_discover().
err	0 if Common Audio Service was found else -ENODATA.
member	Pointer to the set member. NULL if err != 0.
csis_inst	The Coordinated Set Identification Service if Common Audio Service was found and includes a Coordinated Set Identification Service. NULL on error or if remote device does not include Coordinated Set Identification Service. NULL if err != 0.

unicast_start_complete

void(* bt_cap_initiator_cb::unicast_start_complete) (int err, struct bt_conn *conn)

Callback for bt_cap_initiator_unicast_audio_start().

Parameters

err	0 if success, BT_GATT_ERR() with a specific ATT (BT_ATT_ERR_*) error code or -ECANCELED if cancelled by bt_cap_initiator_unicast_audio_cancel().
conn	Pointer to the connection where the error occurred. NULL if err is 0 or if cancelled by bt_cap_initiator_unicast_audio_cancel()

unicast_stop_complete

void(* bt_cap_initiator_cb::unicast_stop_complete) (int err, struct bt_conn *conn)

Callback for bt_cap_initiator_unicast_audio_stop().

Parameters

err	0 if success, BT_GATT_ERR() with a specific ATT (BT_ATT_ERR_*) error code or -ECANCELED if cancelled by bt_cap_initiator_unicast_audio_cancel().
conn	Pointer to the connection where the error occurred. NULL if err is 0 or if cancelled by bt_cap_initiator_unicast_audio_cancel()

unicast_update_complete

void(* bt_cap_initiator_cb::unicast_update_complete) (int err, struct bt_conn *conn)

Callback for bt_cap_initiator_unicast_audio_update().

Parameters

err	0 if success, BT_GATT_ERR() with a specific ATT (BT_ATT_ERR_*) error code or -ECANCELED if cancelled by bt_cap_initiator_unicast_audio_cancel().
conn	Pointer to the connection where the error occurred. NULL if err is 0 or if cancelled by bt_cap_initiator_unicast_audio_cancel()
