flutter_elink_ble 0.2.4

ElinkThings BLE SDK plugin for scanning, connecting, and processing Elink BLE data.

0.2.4

• Fixed iOS session cleanup so stale async callbacks from an old connection can no longer remove a newer session for the same remoteId.
• Changed iOS RSSI, write, A6/A7, BM version, and MTU operations to return a device_not_connected MethodChannel error when the target session is not ready, while still emitting the native error event.
• Updated the example iOS project to the Flutter 3.41 UIScene template and refreshed the CocoaPods lockfile to match the plugin version.

0.2.3

• Deprecated Flutter-layer manual handshake helpers; Android and iOS now emit handshakeEvents from the native SDK handshake callbacks.
• Kept explicit enhanced BM version query 0x46 because the Android native SDK only auto-queries the legacy 0x0E BM version command.
• Changed ElinkBle.getBmVersion() to call the native SDK enhanced BM version query (getBleVersion46 on Android and GetBMVersionPro on iOS) instead of writing the A6 payload directly from Dart.
• Removed Flutter-layer direct BM version payload builders and parsers; BM version results now come from native SDK callbacks.
• Removed the explicit legacy 0x0E BM version query API; native legacy BM version reports are still bridged through bmVersionEvents.
• Added BM version command metadata so Dart can classify native 0x0E reports as legacy and 0x46 reports as enhanced.
• Optimized WiFi provisioning failure-state parsing by merging 0xAB failure reasons into status events, normalizing legacy native failure statuses 5/6/7 to connectApFail with failStatus, and dropping stale failure reasons from non-failure WiFi states.
• Updated the example connection page with compact BM version actions and structured BLE log rendering, including BM version command/type output.
• Updated BM version tests and documentation for the native 0x46 query and native BM version callbacks.
• Documented that some Android modules require MTU negotiation before BM version queries return data.

0.2.0

• Breaking: removed disconnectCurrent; disconnect a specific connection with ElinkBle.disconnect(remoteId).
• Added Flutter-controlled Android command resend configuration with ElinkBle.setAndroidCommandResendCount(). resendCount >= 1 enables SDK resend and 0 disables it; default is disabled.
• Added iOS multi-device connection support by routing each remoteId through its own ELAILinkBleManager session. Writes, RSSI, MTU queries, and disconnects are now scoped to the target remoteId.
• Optimized iOS connect by trying retrievePeripherals(withIdentifiers:) in the target session before falling back to a session-local scan.
• Scoped Flutter A6 handshake state by remoteId so multiple connected devices do not overwrite each other's handshake seed.
• Updated the example app with one tab per connected device, automatic tab switching after connection, per-device logs with per-tab clearing, connected scan-result state, and Android resend-count controls.

0.1.3

• Changed native connect behavior so Android and iOS no longer stop active BLE scanning from inside the plugin.
• Updated the example app's single-device flow to call ElinkBle.stopScan() before connecting the selected device.
• Documented that scan lifecycle ownership belongs to the business layer, so multi-device workflows can keep scanning while connecting devices.

0.1.2

• Added wifiConfigureServerAndConnect for the server-first WiFi provisioning flow: write server host, port, and path before WiFi MAC, password, and connect commands.
• Updated WiFi command sequencing to wait for command responses before sending the next provisioning step.
• Fixed empty server path payloads and exposed reusable server command builders.
• Updated the example WiFi provisioning page with default production server settings and removed the standalone Set Password action.
• Updated README examples to recommend the server-first WiFi provisioning flow.

0.1.1

• Added iOS maximum write length query support via ElinkBle.getIosMtu(). It reports CoreBluetooth .withoutResponse and .withResponse payload limits for the active connection.
• Updated the example connection page so Android requests MTU 517 while iOS reads the negotiated maximum write lengths.
• Documented the example BLE flow for scan, connect, handshake, BM version, and MTU handling.

0.1.0

• Added Dart-side WiFi provisioning support that builds A6 WiFi commands through the shared writeA6 path instead of platform-specific WiFi method-channel calls.
• Added WiFi scan, status, response, MAC, SSID, password, device SN, and server configuration event parsing.
• Added typed WiFi models and streams for access points, connection status, command responses, and generic WiFi events.
• Added a WiFi command log switch. Command logs are disabled by default.
• Added manufacturer data MAC parsing and exposed the parsed MAC on scan results.
• Updated the example app with scan, connection, and WiFi provisioning pages.

0.0.3

• Added ElinkDataProcessor.buildTlvPayloadChunks() for splitting TLV lists into max-length A7 payload chunks.
• Added ElinkDataProcessor.formatHex() and updated the example app to reuse it for byte logs.

0.0.2

• Added common A6/A7 protocol frame parsing, validation, wrapping, and payload helpers.
• Added ElinkPayload as the shared {type, data} object for plain and TLV payload parsing.
• Added ElinkBle.openBluetooth() to guide users to enable Bluetooth.
• Added opt-in TLV parsing for A6/A7 payload logs in the example app; plain parsing remains the default.
• Renamed the model source file from elink_models.dart to elink_ble_models.dart.
• Filtered duplicate consecutive connection state events so repeated connecting logs are not emitted.

0.0.1

• Initial Elink BLE plugin scaffold.
