title: Does each Bluetooth device has its own unique MAC Address? How can we access it in an app?
body: <p>It is my understanding that there is a universally unique identifier associated with all bluetooth devices from the moment they leave the factory door. For instance, also from you link "If a device is discoverable, it will respond to the discovery request by sharing some information, such as the device name, class, and itsunique MAC address." I am explicitly interested in the MAC address and it had better be universally unique. If my assumption is wrong, then that would be a good thing to know too.</p>
