/**
|
|
* Brief:
|
|
* This example Implemented BLE HID device profile related functions, in which the HID device
|
|
* has 4 Reports (1 is mouse, 2 is keyboard and LED, 3 is Consumer Devices, 4 is Vendor devices).
|
|
* Users can choose different reports according to their own application scenarios.
|
|
* BLE HID profile inheritance and USB HID class.
|
|

/**
|
|
* Note:
|
|
* 1. Win10 does not support vendor report , So SUPPORT_REPORT_VENDOR is always set to FALSE, it defines in hidd_le_prf_int.h
|
|
* 2. Update connection parameters are not allowed during iPhone HID encryption, slave turns
|
|
* off the ability to automatically update connection parameters during encryption.
|
|
* 3. After our HID device is connected, the iPhones write 1 to the Report Characteristic Configuration Descriptor,
|
|
* even if the HID encryption is not completed. This should actually be written 1 after the HID encryption is completed.
|
|
* we modify the permissions of the Report Characteristic Configuration Descriptor to `ESP_GATT_PERM_READ | ESP_GATT_PERM_WRITE_ENCRYPTED`.
|
|
* if you got `GATT_INSUF_ENCRYPTION` error, please ignore.
