bluebird 0.6.0

A Bluetooth Low Energy (BLE) plugin for Flutter — scan, connect, and read/write GATT on Android, iOS, macOS, and Web.

0.6.0

• GATT operations are now ordered by the platform, per device, instead of by a global queue in Dart. A call reaches the platform as soon as it is made, so a janky UI no longer stretches the gap between one operation and the next, and one device's operations no longer wait on another's. Connects are still made one at a time across all devices. Requires the matching bluebird_android, bluebird_darwin and bluebird_web.
• Giving up on an operation (its timeout) no longer makes the next one fail with operationInProgress until the abandoned one finishes: the next one waits its turn instead. An operation the platform never completes fails with timeout after 35 seconds and, if it was an ATT transaction, disconnects the device, since the link cannot carry another one.
• disconnect() (with queue: true) now waits for the operations already requested of that device, rather than for every device's.

0.5.1

• Fixed a cancelled scan never finishing its teardown in a widget test, which refused every later scan in that test.
• (Android) Fixed a manufacturer data scan filter with no data matching every advertisement. Requires bluebird_android 0.5.1.

0.5.0

• Fixed connection and scan issues that could leave the plugin stuck.
• adapterState reports a refused permission on every platform; a scan Android blocks on the location toggle fails with locationDisabled.

0.4.4

• Fixed a scan refused by the platform hanging forever instead of failing. When startScan was rejected — the adapter off, the permission denied — the internal advertisement controller was closed without ever having been listened to, so close() never completed: no error reached the caller, the stream never ended, isScanning stayed true, and every later scan was wedged behind operationInProgress for the life of the process.
• (Darwin) Fixed every non-poweredOn adapter state being reported as adapterOff. unauthorized now surfaces as permissionDenied and unsupported as unsupported, from startScan, connect, and the operations failed when the adapter goes away mid-flight. The three call for different things from the user — Control Centre, the settings app, and nothing at all — and were indistinguishable to callers. Requires bluebird_darwin 0.4.4.

0.4.3

• Fixed a scan outliving the adapter it runs on: Bluebird.performScan(...) now also ends when the adapter goes unauthorized or unavailable, not only off/turningOff. Authorization can be revoked from the settings app mid-scan, and the adapter can disappear; either leaves the native scan dead while the stream stays open, waiting for advertisements that can never arrive.
• (Android) bluebird_android no longer applies the Kotlin Gradle Plugin, so it drops off the "uses plugins that apply KGP" warning list that future Flutter versions will turn into a build failure. Requires bluebird_android 0.4.3.

0.4.2

• Fixed (Web) a spurious deviceDisconnected when a device is disconnected and quickly reconnected: a delayed gattserverdisconnected event from the previous connection could tear down the new one. Requires bluebird_web 0.4.2.

0.4.1

• Fixed (Android) AdvertisementData.manufacturerData when an advertisement carries more than one manufacturer specific data structure. Each structure is now keyed by its own company id, instead of being merged into a single blob under the first company id (which leaked later structures' ids into the earlier payload). Requires bluebird_android 0.4.1.

0.4.0

• Added L2CAP connection-oriented channel support. device.openL2capChannel(psm, secure: …) returns a BluetoothL2CapChannel — a bidirectional byte stream to the peer (input / write(...) / close()), independent of GATT, on Android (API 29+) and iOS/macOS (unsupported on Web; secure is Android-only). Data flows over a dedicated binary channel with backpressure in both directions and does not pass through the global GATT operation queue, so its throughput neither gates nor is gated by characteristic I/O. The channel closes on its own when the peer closes it or the device disconnects.
• Breaking: AdvertisementData.advName is now String?. It is null when the advertisement carries no name, rather than being coerced to an empty string. mergedWith carries the prior name forward whenever newer.advName is null.

0.3.0

• Breaking: BluetoothConnectionState now has connecting and disconnecting in addition to connected / disconnected. They are synthesized on the Dart side around device.connect() / disconnect() (the platforms only report the terminal states), so device.connectionState drives a connecting/disconnecting spinner directly. device.isDisconnected is removed — it was ambiguous with the new transient states; use !device.isConnected, or connectionState.value == BluetoothConnectionState.disconnected for a fully-disconnected device.
• Added an optional timeout to Bluebird.scan(...): the scan stops and the stream completes normally (not with an error) after the duration, so Bluebird.scan(timeout: …).accumulate().last yields the final device list. Also hardened the advertisement feed against add-after-close.

0.2.1

• Stopped re-exporting Level / Logger / LogRecord from package:logging, which collided with a consumer's own package:logging import (unnecessary_import). If you configure Bluebird.logger directly, add package:logging to your pubspec.yaml.

0.2.0

• Breaking: logging now flows through a single package:logging Logger, exposed as Bluebird.logger (with Level, Logger, and LogRecord re-exported). Nothing is printed by default — attach an onRecord listener, or call Bluebird.configureLoggerPrinting() for a console one-liner. The previous string log stream and default print output have been removed.
• Breaking: renamed Bluebird.setLogLevel to setPlatformLogLevel (and logLevel to platformLogLevel) and removed its color argument. It now sets only the native logcat / os_log verbosity; Dart-side output is filtered with Bluebird.logger.level. Records are path-scoped ([remoteId][service][characteristic] …), with platform-channel call tracing at Level.FINEST.
• Breaking: reworked error codes around ATT protocol errors. BluebirdErrorCode.gattError/cbError are replaced by androidError/darwinError (local stack or link failures) and attError (the peer answered with an ATT Error Response). A new BluetoothAttException — with AttError constants and attError — surfaces peer rejections with their raw one-octet code, uniformly across platforms.
• characteristic.notifications and characteristic.values are now broadcast streams: several listeners share one notify enable, and notify is released when the last idle listener (e.g. a mobx ObservableStream or StreamBuilder) cancels.
• Fixed Web/WASM compatibility: platform detection no longer pulls dart:io into the web build (it is now behind a conditional import), so the package is Web- and WASM-compatible.

0.1.0

• Initial release.
