CC2540 连接 USB HID设备透传

还有一个HIDEmuKbd的例程，简介如下：

HID Emulated Keyboard
This sample project implements the HID Over GATT profile in a BLE peripheral device to provide an example of how a HID keyboard can be emulated with a simple two button remote control device. The project is based on adopted profile and service specifications for HID over GATT ([8] and [9]) and Scan Parameters ([10] and [11]). The project also includes the Device Information Service ([12]) and Battery Service ([13]).

您好，我看了一下HIDEmuKbd例程，我将它移植到simplePeripheral例程上，仅仅需要HID report部分，但是，我看不明白的是，HID report的Read和Send是在哪部分呢，按我的理解hidDevSendReport应该是往上GATT层的。
