Brian Lough | Turn your HC-05 into a HID Bluetooth device (No Parallel Port Method) @BrianLough | Uploaded October 2017 | Updated October 2024, 5 days ago.
Flash HID firmware on to a $3 Bluetooth devices so you make it act like a Bluetooth keyboard/mouse or game pad! You can use either a HC-06 or HC-05 for this

Unlike other methods for doing this, this method does involve a parallel port so it should work on most computers.

NOTE: Please read pinned comment, there is certain styles of board this won't work on
