问题描述
iPad（中央）的HCI日志：
nRF Connect日志：
我的Mac（外围设备）出现HCI日志错误之一：
我正在尝试从Mac播发CoreBluetooth HID外围设备，并将其连接到另一台设备。广告效果很好，我可以在iPad设置的“蓝牙”部分下看到“外围设备”。但是，当我尝试从iPad连接到我的外围设备时，它显示已连接，但15秒钟后它立即断开连接。这是我到目前为止的代码：

我看了看HOGP文档，对于可能的问题我有一些想法，但是我不知道如何实现它们。我可能没有正确设置这些标志，但是我在网上看了一下，不确定如何更改它。我的L2CAP频道可能使用了错误的PSM，但是我不知道在发布L2CAP频道时如何指定要打开哪个PSM。 didReceiveRead请求未运行，没有错误消息，并且didOpen channel未运行。我相信已经添加了HOGP的所有依赖项（HID，设备信息，电池）。我在做什么错了？
更新：外围设备在连接15秒后，中央服务器尝试发现服务，然后断开连接。我注意到的另一件事是，当我尝试发现服务时，信号之间的间隔（nRF Connect上的符号）更改为N / A，但我不知道这是否相关。 iPad HCI（文本）：
