插件介绍

基于插件公开信息、社区数据与项目使用情况整理的选型参考。

一个轻量级的 Flutter 包，用于在 Android 上连接和通信蓝牙串行设备。它支持 Flutter 应用与兼容硬件（如传感器、微控制器或自定义 IoT 设备）之间双向数据传输，使用标准蓝牙串行协议。该库抽象了低级别的蓝牙操作，提供易于使用的 API 来扫描、配对以及发送/接收数据。专为 Android 设计，支持基本蓝牙功能，无需复杂配置。

适合场景

连接到基于Arduino的设备
从蓝牙模块传输传感器数据
通过蓝牙控制物联网设备
与自定义硬件外设集成
在移动应用中实现实时数据交换

主要特点

蓝牙通信的简单API
仅支持 Android
双向数据传输
设备发现和配对
轻量且依赖极少

适合对象

物联网应用开发者
硬件集成项目
教育机器人
嵌入式系统原型设计
仅限Android的蓝牙应用程序

使用建议

仅限Android平台
不支持 iOS
需要在清单中授予蓝牙权限
取决于设备与串行协议的兼容性
基本功能集，不包含高级蓝牙配置文件

`flutter_bluetooth_serial`

Flutter basic implementation for Classical Bluetooth (only RFCOMM for now).

Features

The first goal of this project, started by @edufolly was making an interface for Serial Port Protocol (HC-05 Adapter). Now the plugin features:

Adapter status monitoring,
Turning adapter on and off,
Opening settings,
Discovering devices (and requesting discoverability),
Listing bonded devices and pairing new ones,
Connecting to multiple devices at the same time,
Sending and receiving data (multiple connections).

The plugin (for now) uses Serial Port profile for moving data over RFCOMM, so make sure there is running Service Discovery Protocol that points to SP/RFCOMM channel of the device. There could be max up to 7 Bluetooth connections.

For now there is only Android support.

  flutter_bluetooth_serial: ^0.4.0

Installing

flutter pub get

Importing

import 'package:flutter_bluetooth_serial/flutter_bluetooth_serial.dart';

Usage

You should look to the Dart code of the library (mostly documented functions) or to the examples code.

// Some simplest connection :F
try {
    BluetoothConnection connection = await BluetoothConnection.toAddress(address);
    print('Connected to the device');

    connection.input.listen((Uint8List data) {
        print('Data incoming: ${ascii.decode(data)}');
        connection.output.add(data); // Sending data

        if (ascii.decode(data).contains('!')) {
            connection.finish(); // Closing connection
            print('Disconnecting by local host');
        }
    }).onDone(() {
        print('Disconnected by remote request');
    });
}
catch (exception) {
    print('Cannot connect, exception occured');
}
