Why does the MAC Addresses change on these devices? They should not change; every device has an associated MAC ID and they should not change; even with an update of firmware. Something is fishy here!!!
They change because the of the state of the BT address, depending if its set to be public or private(resolvable or non-resolvable). Since you wouldn’t want just everyone knowing your private BT address also known as a static address, it gets scrambled by a thing called a Identity Resolving Key. I don’t know that much about the IRK, or how it exactly works, but I do know depending on how the advertising message is set in the header will determine if it displays the static(actual MAC address) or a scrambled one. I’m in no way an expert on this, so if anyone else knows more please chime in, but I think that is why it changes.
