I want to pair a bluetooth keyboard to an arduino project, so that pressing a key on the keyboard causes an action to happen on the Arduino. Let's say that pressing Q on the keyboard makes an LED turn on, and pressing W makes it turn off.

I know that I need some sort of bluetooth module connected to the Arduino, and I need to pair the keyboard to the module. I also know that it must be a module that can act in Master mode and use the HID protocol. But I cannot find a module that does what I want. For example, the HC05 module cannot do HID.

Has anyone done this? Can you tell me which module you used please? I don't want to involve anything else, just an Arduino, a module, and a bluetooth keyboard.
