Android bluetooth protocols and Arduino


First, I'm sorry for my english which is maybe not good at all, i'm french :o

So, I'm working on a project wich can seems to be easy to make: I want to use an arduino to make a LED comes on when I recieve a call on my smartphone.

But the constraint is that I don't want to use an app on my smartphone. Only bluetooth connect and then the arduino runs.

To do it, I have to use profiles like HFP, and later MAP because I want to do same for messages.

The Bluetooth module that I want to use is BC127, because it seems to be the only one wich supports HFP and MAP profiles. I just want to be sure that I have understood, if this module supports HFP and MAP profiles, then I can do what I want to do ?

If it's ok, do you have more informations how I can do this, how to use theses profils, I can admit that I don't have a lot of experience about arduino programming, even less on Bluetooth use :disappointed_relieved:

Thank you a lot guys

How is it going? I would do a similar project but I can't find info about this topic
