I wan't to buy an old rotary phone and use an Arduino to connect it to my iPhone to make calls. I have tried to look through some forums, but I can't find any clear instructions on how to do this. As I see it there are two possibilities;
- Connect the Arduino to my iPhone using a BT module.
- Connect the Arduino to my iPhone using the lightning port.
So, in order to make calls with my iPhone, I would need to send the number dialled by the rotary phone and make the iPhone start the call. Also, I need to detect when the iPhone recieves a call and send this to the rotary phone. From what I understand I would need to make a custom app on the iPhone to do this, what do you guys think? Can anyone give me some hints on how to do this, or if it is possible at all?
