  467. <ol>
    468. 

  468. <li>
    469. 

  469. <p><strong>单例模式</strong>：<code>BLEServiceImpl</code> 使用单例模式，全局共享同一个连接状态</p>
    470. 

  470. </li>
    471. 

  471. <li>
    472. 

  472. <p><strong>自动握手</strong>：<code>connect()</code> 方法内部自动完成握手，无需单独调用握手方法</p>
    473. 

  473. </li>
    474. 

  474. <li>
    475. 

  475. <p><strong>线程安全</strong>：BLE 回调可能在非主线程执行，需要在回调中使用 <code>activity?.runOnUiThread {}</code> 切换到主线程更新 UI</p>
    476. 

  476. </li>
    477. 

  477. <li>
    478. 

  478. <p><strong>错误处理</strong>：所有 API 都通过 <code>BLEResponse</code> 返回结果，需要检查 <code>response.success</code> 判断是否成功</p>
    479. 

  479. </li>
    480. 

  480. <li>
    481. 

  481. <p><strong>生命周期管理</strong>：建议在 <code>onDestroyView()</code> (Fragment) 或 <code>onDestroy()</code> (Activity) 中调用 <code>disconnect()</code> 断开连接</p>
    482. 

  482. </li>
    483. 

  483. <li>
    484. 

  484. <p><strong>获取服务实例</strong>：推荐使用 <code>BLEServiceFactory.create(context)</code> 获取服务实例（工厂方法内部使用单例模式）</p>
    485. 

  485. </li>
    486. 

  486. <li>
    487. 

  487. <p><strong>Fragment 中使用</strong>：在 Fragment 中使用时，使用 <code>requireContext()</code> 获取 Context，回调中使用 <code>activity?.runOnUiThread {}</code> 更新 UI</p>
