• Added SPM Package.swift files for iOS/macOS to support Swift Package Manager integration.
• Enabled public_member_api_docs lint and added initial dartdoc stubs across the public API to improve documentation coverage.
• Updated package metadata (homepage, repository, issue tracker) and topics to point to the canonical repository.
• Minor Android build script adjustments to reduce legacy Kotlin warnings.

1.0.0

Initial release — August 3, 2026

Central Role (All 6 Platforms)

• Scan for nearby BLE devices with service UUID filters, scan modes, and duplicate filtering
• Connect/disconnect with timeout and auto-reconnect support
• Real-time connection state tracking — isConnected, connectionState, stateStream
• Discover services, characteristics, and descriptors
• Read, write (with/without response), and subscribe to characteristic notifications/indications
• Read and write descriptors
• Request MTU size (Android; iOS/macOS auto-negotiate)
• Read RSSI of connected devices
• Connection parameter requests (Android requestConnectionPriority)

Bond / Pair Management

• createBond() — initiate pairing (Android explicit, iOS/macOS auto, Linux via BlueZ Pair())
• removeBond() — remove pairing (Android via reflection, Linux via RemoveDevice)
• bondState — query current bond state: none, bonding, bonded
• bondStateStream — real-time bond state change events via BroadcastReceiver (Android)
• iOS/macOS: Pairing handled automatically by CoreBluetooth when accessing encrypted characteristics

Peripheral Role (Android, iOS, macOS)

• Advertise as a BLE peripheral with custom local name and service UUIDs
• GATT server: add/remove services with multiple characteristics
• Handle read and write requests from centrals
• Send notifications and indications to subscribed centrals
• Multi-central support (multiple centrals connected simultaneously)
• Subscription change events

L2CAP Channels (Android 10+, iOS 11+, macOS 10.14+)

• Open L2CAP Connection-Oriented Channels for high-throughput streaming
• Publish L2CAP channels from peripheral side
• Read/write data streams on L2CAP channels

Background Support

• iOS: CoreBluetooth state restoration via iosRestorationIdentifier
• Android: Foreground service support architecture

Error Handling

• Sealed BleError hierarchy: BleConnectionError, BleGattError, BleTimeoutError, BlePermissionError, BleScanError, BleUnsupportedError
• Platform error codes propagated from native layer
• GattErrorCode enum for typed GATT error handling

Logging

• Configurable BleLogger with levels: verbose, debug, info, warning, error, none
• Custom onLog callback for integration with any logging framework

Platform Support

• Android — Full Central + Peripheral via BluetoothGatt / BluetoothGattServer
• iOS — Full Central + Peripheral via CoreBluetooth
• macOS — Full Central + Peripheral via CoreBluetooth
• Web — Central only via Web Bluetooth API (Chrome/Edge, requires HTTPS)
• Linux — Central only via BlueZ D-Bus
• Windows — Central only via WinRT BLE APIs

Platform-Specific Limitations

• Web: No peripheral role, no L2CAP, no background. Scanning uses device picker (user gesture required). Chrome/Edge only.
• Linux: Central role only. No peripheral, L2CAP, or background support. Requires BlueZ.
• Windows: Central role only. No peripheral, L2CAP, or background support. Requires Windows 10+.
• iOS/macOS: MTU is auto-negotiated (cannot set manually). Connection parameters are read-only.
• Android: L2CAP requires API 29+ (Android 10). BLUETOOTH_ADVERTISE permission required for peripheral role.

Architecture

• Instance-based API (no global singletons) — fully testable and mockable
• Federated platform interface via BlePlusPlatform with PlatformCapabilities feature detection
• Separate event channels per concern: scan, connection, characteristic, peripheral
