Please help,How to add Camera Control to hidReportDescriptor

[YuiLeung]

I am developing a mobile phone camera remote control. I know that the volume button can take pictures, but if my camera uses the camera button, it can trigger continuous shooting.

I checked the information and found that the Camera Control Page (0x90) in the hut1_4.pdf document contains the focus and camera buttons. I downloaded the hutrr49_camera_controls.pdf document and found the ReportDescriptor data. However, no matter how I add it to BleKeyboard.cpp, it fails. It doesn't work, can anyone help me?

Sample Report Descriptor:

COLLECTION (Application) A1 01
USAGE_PAGE (Camera Control) 05 90
USAGE_MINIMUM (Camera Auto-Focus) 19 20
USAGE_MAXIMUM (Camera Shutter) 29 21
LOGICAL_MINIMUM (0) 15 00
LOGICAL_MAXIMUM (1) 25 01
REPORT_SIZE (1) 75 01
REPORT_COUNT (2) 95 02
INPUT (Data,Var,Abs) 81 02
REPORT_SIZE (6) 75 06
REPORT_COUNT (1) 95 01
INPUT (Cnst,Ary,Abs) 81 01
