user54149: I'm new to wireless communication on Arduinos and doing research for a project. I'm looking at the Arduino Leonardo (which is like the Uno) which via its micro USB port can be automatically recognized as a mouse/keyboard. But also looking at a regular Uno wiFi Rev2.
I want to achieve the same result, but wirelessly via Bluetooth. Because I need to connect it to a device that only recognizes Bluetooth mice/keyboards and nothing else. If I buy something like the HC-05 how would the chip report itself? 
How is the Bluetooth stack handled with regards to identification and authentication? Does it somehow copy the USB mouse/keyboard setup?
PS: Can anyone tell me if the Wifi Arduinos (Uno WiFi rev2) also have Bluetooth embedded?

As an SPP. I.e., a serial port.

How is the bluetooth stack handled with regards to identification and authentication?

By the firmware on the HC-05

Does it somehow copy the usb mouse/keyboard setup?

No.
You need a USB device that can emulate a keyboard. That's not the HC-05. The host microcontroller has absolutely nothing to do with what capabilities the bluetooth interface has.
