用Flutter开发蓝牙全站仪
Flutter提供了一个名为flutter_blue的插件,可以使用它来实现蓝牙通信。在蓝牙配网的过程中,通常需要将手机连接到要配网的设备的热点,然后使用手机向设备发送配网信息,这个过程中需要用到蓝牙通信。
以下是一个简单的蓝牙配网的示例:
1. 在pubspec.yaml文件中添加flutter_blue插件的依赖:
```
dependencies:
flutter_blue: ^0.7.3
```
2. 导入flutter_blue库:
```
import 'package:flutter_blue/flutter_blue.dart';
```
3. 扫描设备并连接到要配网的设备:
```
FlutterBlue flutterBlue = FlutterBlue.instance;
// 扫描设备
flutterBlue.scan(timeout: Duration(seconds: 4)).listen((scanResult) {
// 连接到要配网的设备
if (scanResult.device.name == "要配网的设备名称") {
scanResult.device.connect();
}
});
```
4. 连接成功后,发送配网信息:
```
// 监听连接状态
bool isConnected = false;
scanResult.device.state.listen((state) {
if (state == BluetoothDeviceState.connected) {
isConnected = true;
}
});
// 发送配网信息
if (isConnected) {
List<int> data = [0x01, 0x02, 0x03]; // 要发送的配网信息
await scanResult.device.discoverServices();
List<BluetoothService> services = await scanResult.device.services.toList();
for (BluetoothService service in services) {
List<BluetoothCharacteristic> characteristics =
await service.characteristics.toList();
for (BluetoothCharacteristic characteristic in characteristics) {
await characteristic.write(data);
}
}
}
```
以上代码仅为示例,具体实现过程可能因具体设备而异,需要根据实际情况进行调整。
