安装

你可以使用我们的 AI 辅助设置来安装插件。使用以下命令将 Capgo skills 添加到你的 AI 工具中：

npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

然后使用以下 prompt：

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-bluetooth-low-energy` plugin in my project.

如果你更想手动设置，请运行以下命令安装插件，并按照下方各平台的说明操作：

bun add @capgo/capacitor-bluetooth-low-energy
npx cap sync

导入

import { BluetoothLowEnergy } from '@capgo/capacitor-bluetooth-low-energy';

快速入门

import { BluetoothLowEnergy } from '@capgo/capacitor-bluetooth-low-energy';

await BluetoothLowEnergy.initialize({ mode: 'central' });

示例：shimWebBluetooth

import { BluetoothLowEnergy } from '@capgo/capacitor-bluetooth-low-energy';

BluetoothLowEnergy.shimWebBluetooth();

示例：isAvailable

import { BluetoothLowEnergy } from '@capgo/capacitor-bluetooth-low-energy';

const { available } = await BluetoothLowEnergy.isAvailable();

常见坑点

权限: 调用 checkPermissions() 然后 requestPermissions() 在需要时。
监听器: 在页面卸载时移除句柄。
初始化一次: 在应用启动时运行 setup。
