How to read Bluetooth Address with an HC05 and an arduino

Hi, i'm a very beginner and i want to read the Bluetooth Address (BD_ADDR, 12 chs) of my android phone or other bluetooth devices around my HC05 module

How i can do it ?

Edit: if there is no known method of reading it, the idea is that i want to open my car's door when aproching with my phone and another way to do it, may be with an application on my phone witch sends a code to the HC05, whenever it detected

I don’t think you need the address. I think you are right on the second bit. Just try a Bluetooth Auto connect app first. I don’t think you need an Arduino. I believe HC-05 just needs a constant 5v, is configured to sniff for Android, and works the lock when the status changes.
