Bluetooth Address Structure

Apr 2, In reply to Lee Leon: The TI guy has this marked as solved so he's not looking any more. Maybe I can help. As I understand it: The link-level "Access Address" on an advertisement may be: MAY change when chip is rebooted, otherwise unchanging.

The rest is just a bit random number that changes every few minutes or so. The rest of the most significant half is a bit random number that changes every few minutes or so, the other half is a bit hash of it by a bit Identity Resolving Key IRK. The key is that peripheral's identity. If it doesn't have the peripheral's key, it can still connect if it passes any other handshake checks.

But once it's disconnected again and the random number changes, it loses track of the peripheral, which is now a "new peripheral" to it again. I think the main risks with a private static address are: Do they both have to be unique?

    If those other devices have a MAC that means that MAC is not in any way associated with the ethernet or internet protocols and is completely independent. Bluetooth devices are assigned addresses similarly to Ethernet - an organizationally unique identifier OUI of 3 bytes followed by another 3 bytes assigned by the vendor.

    Bluetooth OUI lookup tools can be found on Google. Each device on a Bluetooth network has its own HW address just like Ethernet. The Bluetooth specification actually lays out both L1 and L2 and, like Ethernet, allows for multiple upper-layer protocols to be mapped ex:
