Struct BroadcastAudioScanServiceClient

pub struct BroadcastAudioScanServiceClient<T: GattTypes> { /* private fields */ }

Manages connection to the Broadcast Audio Scan Service at the remote Scan Delegator and writes/reads characteristics to/from it.

Implementations

impl<T: GattTypes> BroadcastAudioScanServiceClient<T>

pub fn create_for_test( gatt_client: T::PeerService, audio_scan_control_point: Handle, ) -> Self

pub async fn create(gatt_client: T::PeerService) -> Result<Self, Error>

where <T as GattTypes>::NotificationStream: Send,

pub fn take_event_stream( &mut self, ) -> Option<impl Stream<Item = Result<Event, Error>> + FusedStream>

Returns a stream that can be used by the upper layer to poll for BroadcastAudioScanServiceEvent. BroadcastAudioScanServiceEvents are generated based on BRS characteristic change received from GATT notification that are processed by BroadcastAudioScanServiceClient. This method should only be called once. Returns an error if the method is called for a second time.

pub async fn remote_scan_started(&self) -> Result<(), Error>

Indicates to the remote BASS server that we have started scanning for broadcast sources on behalf of it. If the scan delegator that serves the BASS server is collocated with a broadcast sink, this may or may not change the scanning behaviour of the the broadcast sink.

pub async fn remote_scan_stopped(&self) -> Result<(), Error>

Indicates to the remote BASS server that we have stopped scanning for broadcast sources on behalf of it.

pub async fn add_broadcast_source( &self, broadcast_id: BroadcastId, address_type: AddressType, advertiser_address: [u8; 6], sid: AdvertisingSetId, pa_sync: PaSync, pa_interval: PaInterval, subgroups: Vec<BigSubgroup>, ) -> Result<(), Error>

Provides the BASS server with information regarding a Broadcast Source.

pub async fn modify_broadcast_source( &self, broadcast_id: BroadcastId, pa_sync: PaSync, pa_interval: Option<PaInterval>, bis_sync: Option<HashMap<SubgroupIndex, BisSync>>, metadata_map: Option<HashMap<SubgroupIndex, Vec<Metadata>>>, ) -> Result<(), Error>

Requests the BASS server to add or update Metadata for the Broadcast Source, and/or to request the server to synchronize to, or to stop synchronization to, a PA and/or a BIS.

Arguments

• broadcast_id - id of the broadcast source to modify
• pa_sync - pa sync mode the scan delegator peer should attempt to be in
• pa_interval - updated PA interval value. If none, unknown value is used
• bis_sync - desired BIG to BIS synchronization information. If empty, it’s not updated
• metadata_map - map of updated metadata for BIGs. If a mapping does not exist for a BIG, that BIG’s metadata is not updated

pub async fn remove_broadcast_source( &self, broadcast_id: BroadcastId, ) -> Result<(), Error>

pub async fn set_broadcast_code( &self, broadcast_id: BroadcastId, broadcast_code: [u8; 16], ) -> Result<(), Error>

Sets the broadcast code for a particular broadcast stream.

pub fn known_broadcast_sources(&self) -> Vec<(Handle, BroadcastReceiveState)>

Returns a list of currently known broadcast sources at the time this method was called.

pub fn insert_broadcast_receive_state( &mut self, handle: Handle, brs: BroadcastReceiveState, )
