BLE transport implementation using L2CAP Connection-Oriented Channels (SeqPacket mode) via the bluer crate, behind cfg(feature = "ble"). Core transport: - BleTransport<I> generic over BleIo trait (BluerIo prod, MockBleIo test) - Connection pool with priority eviction (static > discovered, max 7) - Connect-on-send via connect_inline() matching TCP behavior - Per-connection receive loops with pool cleanup on disconnect Discovery and probing: - Combined scan_probe_loop using select! over scanner events and a BinaryHeap delay queue with per-entry random jitter (0-5s) to prevent herd effects when multiple nodes see the same beacon simultaneously - Pre-handshake pubkey exchange ([0x00][pubkey:32]) for IK identity - Cross-probe tie-breaker: smaller NodeAddr's outbound wins (same convention as FMP/FSP rekey dual-initiation) - Probed peers reported to DiscoveryBuffer; pool fills through normal node-layer auto-connect -> send_async -> connect_inline path Beacon management: - Periodic advertising: 1s burst every 30s (configurable via beacon_interval_secs / beacon_duration_secs) - FIPS service UUID for scan filtering Configuration (all fields optional with defaults): - adapter, psm, mtu, max_connections, connect_timeout_ms - advertise, scan, auto_connect, accept_connections - beacon_interval_secs (30), beacon_duration_secs (1) Hardware validated with two BLE nodes: - 2048-byte MTU, ~60-160ms RTT, zero-config auto-connect - BLE spike tool at testing/ble/ for standalone adapter validation 42 unit tests + 4 node-level integration tests, all CI-compatible via MockBleIo (no hardware required). tokio test-util added for time-dependent scan/probe tests.
