I am trying to find a way to detect an incoming call on my iphone via Bluetooth connection to arduino. I don't want to use gsm module or wifi. It must be done via bluetooth and I also don't want to use any phone apps. I want I light to flash as soon as my phone receives an incoming call. This must only hapoen for incoming calls and not for messages coming in or out, only calls in.
I've tried so many different things and nothing seems to working. Not even sure if this is possible to do.
there has already been a topic about this ...
Hi.
I made a Nano/Bluetooth device to receive a code when the phone received a call or SMS. However, it used an app on the phone and the phone's built-in BT capability.
The app was not difficult to build or install.

This has nothing to do with Arduino.
A microphone connected to a small audio amp, with rectified output. Feed that into the Arduino and you will be able switch when the ringtone is sensed. You can avoid false triggering by selection of ring tone and amplifier input filtering. I can't think of any other way thatIt could be done.
