我正在研究android中的蓝牙应用程序。我正在ICS上写一个FindMe Server应用程序。我们在ICS中采用了Gatt方法，因为我们正致力于低能耗。我目前没有使用FindMe配置文件API，因此尝试使用GATT方法来完成应用程序。我的应用程序正在注册GATT，它也在进行服务发现，但在突然进行服务发现时，蓝牙设备与我的手机断开连接。你能告诉我出了什么问题吗？

答案 0 :(得分：0)
你能找到根本原因吗？由于你还没有发布，所以我很想你可能没有。 从共享源代码中可以看出，您的应用程序使用的是来自Qualcomm，broadcomm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Air Sniffed日志来了解断开连接的真正原因会很有帮助。 您的FindMeService对我来说是正确的。但我个人希望看到Air Sniff日志。
谢谢，干杯!!
