Re: public ID addresses

Hello Johan,

Thanks for your suggestion. Upon further investigation, the CONFIG_BLUETOOTH_PRIVACY=y in the prj.conf file in zephyr/samples/bluetooth/peripheral. From my understanding, this config allows for the use of resolvable private addresses and that there should be a key to decipher the static address. How do you find out what this key is? Can you provide any information about this? Thank you for your time.

Thank you,
Tamra

This PR is merged now, so simply rebuilding and flashing your nRF51 &
Quark SE Zephyr images from the upstream master branch should yield a
solution where the Bluetooth address remains the same.
