Turbo J Can you please guide me how to get this "actual address" programatically?

Is that a modern-ish phone?

Because an MSB of 0x44 looks a lot like a private resolvable address, and these randomize (IMHO every 15 minutes at least).

Modern phones use this for privacy reasons. The actual address is exchanged during the pairing/bonding procedure.

Hi Turbo,

Thank you for your quick response.

Tried using peer addr in connected part but the output still doesn't match.

It prints "addr of app 0x84 0x39 0x87 0x46 0x89 0x44" and the prints aren't same whenever the nrf dev kit is power cycled.

Regards,

Shafi

Your are using the wrong field from the uinion. Use the fields in the "connected" part.
