好吧，我正在构建一个带有用作鼠标的集成触摸屏的键盘，我通过HID OVER GATT发送通过BLE生成的数据。这适用于org.bluetooth.characteristic.boot_keyboard_input_report＆amp; org.bluetooth.characteristic.boot_mouse_input_report，但我不太确定如何根据这些声明配置report_map以及我需要发送的内容。
主要问题是，因为没有混合类型的用法，我需要使用两个用法。但是我需要第二个使用页面吗？如何定义这种混合设备的集合（应用程序）？
Usage Page
Usage Keyboard
??Usage Page
Usage Mouse
所以我像这样定义了我的report_map：
0x05, 0x01, // Usage Page (Generic Desktop),
0x09, 0x06, // Usage (Keyboard),
0xA1, 0x01, // Collection (Application),
0x05, 0x07, // Usage Page (Key Codes);
0x19, 0xE0, // Usage Minimum (224),
0x29, 0xE7, // Usage Maximum (231),
0x15, 0x00, // Logical Minimum (0),
0x25, 0x01, // Logical Maximum (1),

我不完全确定，如果我被允许定义两个使用情况页面，或者我需要创建一个集合，但是那里有所有报告。
我不确定的第二件事是我如何为特定的INPUT报告创建值。他们是否通过报告ID获得了一些我无法获得的编号系统？或者他们必须立即发送（我猜这是对的）。
在我的情况下，报告看起来像这样：
// Output Report
//
// Byte | D7 D6 D5 D4 D3 D2 D1 D0
// ------+---------------------------------------------------------------------
// 0 | NUM_LOCK CAPS_LOCK SCROLL_LOCK COMPOSE KANA CONSTANT CONSTANT CONSTANT
// Input Report for Keyboard
// Byte | D7 D6 D5 D4 D3 D2 D1 D0
// ------+---------------------------------------------------------------------
// 0 | LEFT_CTRL LEFT_SHIFT LEFT_ALT LEFT_OS RIGHT_CTRL RIGHT_SHIFT RIGHT_ALT RIGHT_OS
// 1 | Reserved please leave at 0
// 2-7 | Keycodes
// Input Report for Pointer
// Byte | D7 D6 D5 D4 D3 D2 D1 D0
// ------+---------------------------------------------------------------------
// 0 | 0 0 0 Forward Back Middle Right Left (Button)
// 1 | X
// 2 | Y
// 3 | Vertical Wheel
// 4 | Horizontal (Tilt) Wheel
