How to get MAC address of bluetooth HC-06

Hi guys!

I have a dynamic serial communication between different arduinos with bluetooth hc-06 module and OF. I’m trying to get an identifier of each hc-06 like an IP addres or MAC address to figured out which arduino i’m communicating.

I’m using ofSerial but if there’re other options I’m opened mind.
Do you know some way to get this information?

What I’m trying it’s to reconnect the arduino if the communication have failed.

Thanks!!
