How to change random static mac address dynamically?

[Jerry Cui]

Hello,

My SDK is ncs 2.6.1, and chip is nRF52832.  If set CONFIG_BT_ID_MAX to 2, bt_id_create can be called twice without failure, but it seems the 2nd call doesn't update the mac address of adv.ertising. Is there a way to change adv mac address without re-boot the device?

Thanks,

Jerry

I followed these instructions:

Hi Jerry,

It is not allowed per Bluetooth specification to change a static address more often than every reboot. If you want to to chage more often, you can advertise with a random address type (resolvable or non-resolvable).
