Android 蓝牙连接丢失问题

这不是我正在开发的东西，更像是我正在调试的东西。出于某种原因，我的HTC Desire HD一直在断开与汽车蓝牙的连接。它在手机的原始rom上运行良好，然后我升级到姜饼HTC rom，它开始断开连接。我不确定接下来发生了什么可能是我安装了什么？mb汽车的电脑在我维修时被重置了？但它实际上在几个月后就开始工作了，一切都很好，直到我再次升级到2.3.5 HTC官方升级。手机连接到我的汽车时没有任何问题，然后在一分钟内断开连接，直到手机或汽车重新启动后才会重新连接。以下是我收集的一些日志数据，以防有人熟悉蓝牙在android上的工作原理：

我的三星Galaxy SII也有同样的问题……我为公司的boot OS闪存了它，问题被改变了……但一个月后，PCB板被炸掉了……所以请把它带到附近的cutomer护理中心，在他们的服务过程中进行闪存……我认为这与你的情况无关，tbh。我以前让它工作过，然后一个月左右没有工作，然后又工作了。还有一个想法——这可能与手机上储存的联系人数量有关？它似乎失败了，一旦达到250+个联系人刷新了电话簿，有255个结果，可能是我以前的联系人少了，或者我的汽车电话簿被删除了..嘿。。运气好吗？我也面临同样的问题。我不知道它是否相关，但每当观察到此问题时，我都会看到此日志：W/HeadsetBase.cpp 1631:RFCOMM poll返回成功1，但带有意外的revents位掩码：0x11 I/HeadsetBase 1631:headset read error 5
