问题：
在ICS中实现FindMe配置文件
邹誉
我正在android上开发蓝牙应用程序。我正在ICS上编写一个FindMe服务器应用程序。我们在研究低能时，已将Gatt方法纳入ICS。我目前没有FindMe配置文件API，因此尝试使用GATT方法来完成应用程序。我的应用程序正在向GATT注册，它也在进行服务发现，但在进行服务发现时，蓝牙设备突然与我的手机断开连接。你能告诉我哪里出了问题吗？？
我已经在这里复制了代码。。。。所有代码都来自一个文件

你能找到根本原因吗？因为你还没有发布，所以我假设可能是你没有。从共享的源代码中，很明显，您的应用程序使用了来自高通、博通和CSR等许多供应商之一的BT-低能耗堆栈。通过实际获取该场景的Air Sniffed日志，了解断开连接的真正原因将很有帮助。您的FindMeService在我看来是正确的。然而，我个人希望看到空气嗅探日志。
谢谢，干杯！！
