Hi Charly, this thread might be good intro to your next reading;)

I edited it for clarity. Hope it's better.

Don't the two phrases: "can be generated every time the device boots up" and "cannot be changed during a power cycle of the device" contradict each other?

Hi Cales, maybe this very helpful information can find it's way into the doxygen documentation? Cheers, Torsten

Hi Charly,

-Public address.

This is a global, fixed address. It must be registered with the IEEE Registration Authority and will never change during the lifetime of the device.

-Random Static address.

A random static address is simply a random number that can either be generated every time the device boots up or can stay the same for the lifetime of the device. But it cannot be changed within a single power cycle of the device.

-Private Resolvable address.

Those are generated from an identity resolving key (IRK) and a random number, and they can be changed often (even during the lifetime of a connection) to avoid the device being identified and tracked by an unknown scanning device. Only devices that possess the IRK distributed by the device using a private resolvable address can actually resolve that address, allowing them to identify the device.

-Private Non-Resolvable address.

Not very commonly used, a random number that you can change anytime.
