Bluetooth is not a starter subject - not in friendly environments such as arduino, so not even remotely in OS development. As the wiki states:

Is there a tutorial on...?
Because this place can not and does not cater for beginner developers, the question for some other place that does provide a tutorial, good explanations or easy to understand reading is often requested. However, they do not exist. Difficult subjects can not be described with light prose, just like there are enough things that are too complicated for a monkey to properly learn. If you have trouble reading official documentation, this would be a good time to practice.
You might find yourself lucky if a bluetooth initiate happens to be around here, but otherwise practising getting all that information on your own would be the best course of action from here on.
