What does the Bluetooth Mouse check ?

I am making input support equipment for people with disabilities.

I built BLE_HID_Mouse (sample code of Cypress).

This is 3ButtonMouse.

Until iPadOS 13.1, there was no problem.



However, a warning is displayed on iPadOS13.4 and 13.4.5Beta.

The same warning is displayed for CY5672 PRoC BLE REMOTE.

BLE_HID_Keyboard does not display a warning.



What does the Bluetooth Mouse check and warn on iPadOS13.4?

Please give me advice on displaying warnings.
