Should be enough to set it once, after startup. If you reset the device, you need to set it again. But if you only turn off/on advertising, it should not be needed to set it each time.

Hi Sigurd,

I was wondering if the public address we write using this method is persistent. Do we need to write it every time before advertising or is the address stored in persistent storage?

These additions solved it. Thanks

Hi,

I did some testing on this, and it seem to work if I call settings_load() between set_bd_addr() and start_advertising();

Snippet:

set_bd_addr();

if (IS_ENABLED(CONFIG_SETTINGS)) {
    settings_load();
}

start_advertising();

in prj.conf I added this:

# Enable bonding
CONFIG_BT_SETTINGS=y
CONFIG_FLASH=y
CONFIG_FLASH_PAGE_LAYOUT=y
CONFIG_FLASH_MAP=y
CONFIG_NVS=y
CONFIG_SETTINGS=y

Would need to investigate this a bit more to understand why this is the case.
