Read MAC address

Hi,

I'm trying to develop a small project where I would use the Puck as a HW identifier, combining Eddystone functionality with a unique ID. I was thinking that I could use the MAC address of the Puck as the ID, Base64 encode it and advertise it as part of the Eddystone URL.

But I can't find a way to read the BT MAC of the device inside the JS code - is it possible?

Thanks, br:
