Bluetooth Arduino + RN-42 HID Module

I am trying to create a “keyboard” using the Arduino Mini Pro and the RN-42 HID Bluetooth . I can connect to it using a MacBook , and it appears as a Bluetooth keyboard. In addition, I can press buttons and send commands.

Perfectly?

Unfortunately, no ... I do not know how to encode the bytes that I need to send to the module in order to inform it of keystrokes and key releases. I read all the Bluetooth RN-42 instructions that I can get, but I do not quite understand what I should send to the Bluetooth module. I searched Google Search for several weeks, and I cannot find the C code that would help me. As far as I know, USB keys are sent as hex arrays. It is right? If so, how would this be done?

If you want Arduino to send messages from the keyboard to the computer, use Keyboard.press () to press keys and Keyboard.release () to release. I don't have this type of Arduino or this Bluetooth module, but since it recognizes the Arduino as a keyboard, I think this should work ...
