Struct BleTransport 

pub struct BleTransport<I: BleIo> { /* private fields */ }

BLE transport for FIPS.

Provides connection-oriented, reliable delivery over BLE L2CAP CoC. Each peer has its own L2CAP connection; the pool enforces hardware connection limits with priority eviction.

Implementations

impl<I: BleIo> BleTransport<I>

pub fn new( transport_id: TransportId, name: Option<String>, config: BleConfig, io: I, packet_tx: PacketTx, ) -> Self

Create a new BLE transport.

pub fn name(&self) -> Option<&str>

Get the instance name.

pub fn stats(&self) -> &Arc<BleStats>

Get the transport statistics.

pub fn io(&self) -> &Arc<I>

Get the I/O implementation (for test injection).

pub fn set_local_pubkey(&mut self, pubkey: [u8; 32])

Set the local public key for pre-handshake identity exchange.

Must be called before start_async(). Without this, BLE connections skip the pubkey exchange and discovered peers won’t have identity information for auto-connect.

pub async fn start_async(&mut self) -> Result<(), TransportError>

Start the transport asynchronously.

pub async fn stop_async(&mut self) -> Result<(), TransportError>

Stop the transport asynchronously.

pub async fn send_async( &self, addr: &TransportAddr, data: &[u8], ) -> Result<usize, TransportError>

Send data to a remote BLE address.

If no connection exists, triggers a background connect and fails fast. The next send retry (typically 1s later for handshake msg1) will find the connection established. This avoids blocking the event loop on L2CAP connect (up to 10s).

pub async fn connect_async( &self, addr: &TransportAddr, ) -> Result<(), TransportError>

Initiate a non-blocking connection to a remote BLE device.

Spawns a background task that connects with timeout and promotes to the pool on success. Poll connection_state_sync() to check.

pub fn connection_state_sync(&self, addr: &TransportAddr) -> ConnectionState

Query the state of a connection attempt.

pub async fn close_connection_async(&self, addr: &TransportAddr)

Close a specific connection.

pub fn link_mtu(&self, addr: &TransportAddr) -> u16

Get the link MTU for a specific address.

Trait Implementations

impl<I: BleIo> Transport for BleTransport<I>

fn transport_id(&self) -> TransportId

Get the transport identifier.

fn transport_type(&self) -> &TransportType

Get the transport type metadata.

fn state(&self) -> TransportState

Get the current state.

fn mtu(&self) -> u16

Get the MTU for this transport.

fn link_mtu(&self, addr: &TransportAddr) -> u16

Get the MTU for a specific link.

fn start(&mut self) -> Result<(), TransportError>

Start the transport.

fn stop(&mut self) -> Result<(), TransportError>

Stop the transport.

fn send( &self, _addr: &TransportAddr, _data: &[u8], ) -> Result<(), TransportError>

Send data to a transport address.

fn discover(&self) -> Result<Vec<DiscoveredPeer>, TransportError>

Discover potential peers (if supported).

fn auto_connect(&self) -> bool

Whether to auto-connect to peers returned by discover(). Default: false. Concrete transports read from their own config.

fn accept_connections(&self) -> bool

Whether to accept inbound handshake initiations on this transport. Default: true (preserves UDP’s current implicit behavior).

fn close_connection(&self, _addr: &TransportAddr)

Close a specific connection (connection-oriented transports only).
