I can connect to the device on a system level, however in my test application... 我可以在系统级别连接到设备，但是在测试应用程序中...
[[EAManager sharedAccessoryManager] connectedAccessories]
returns an empty array. 返回一个空数组。 If I show the built in bluetooth picker, the device also shows up, however fails to connect. 如果显示内置的蓝牙选择器，则该设备也会显示，但无法连接。 Core Bluetooth can see and connect to it via LightBlue though. 核心蓝牙可以通过LightBlue看到并连接到它。
My question is, could this be a hardware issue, or an iOS 8.1.2 bug with Bluetooth Core Specification v4.0? 我的问题是，这可能是硬件问题，还是蓝牙核心规范v4.0的iOS 8.1.2错误？

因此，问题在于认证协处理器上的接线错误，以及固件已过期。
