我正在研究安卓的蓝牙应用程序。我正在ICS上编写一个FindMe服务器应用程序。我们已经将 GATT 方法纳入了 ICS 中，因为我们正在研究低能耗。我目前没有 FindMe 配置文件 API，因此尝试使用 GATT 方法完成应用程序。我的应用程序正在注册到 GATT，它也在执行服务发现，但在执行服务发现时，蓝牙设备突然与我的手机断开连接。你能告诉我出了什么问题吗？
我在这里复制了代码....所有代码都来自单个文件

你能找到根本原因吗？由于您尚未发布，因此我假设您可能没有发布。从共享的源代码中，很明显，您的应用程序使用来自高通，博通和CSR等众多供应商之一的BT-Low-energy堆栈。通过实际获取场景的空气嗅探日志来了解断开连接的真正原因会很有帮助。你的FindMeService对我来说是正确的。但是我个人希望看到空气嗅探日志。
谢谢和干杯！
