Setting public BLE address on nRF5340 - NCS 2.4

[Tyler Grunenwald]

I need to set the public BLE address for a BLE central role device using an nRF5340.

First attempted creating an additional bluetooth identity, but it appears this is only intended for peripheral role devices, as the API for scanning or creating new connections does not allow an ID to be passed in.

Next, I looked at bt_ctlr_set_public_addr() and read:

•  Setting nRF5340 Public BLE Address 
•  nRF5340 - setting public bt address 
•  Setting the BLE Public Address on nRF5340  

I've attempted to duplicate the procedures in the answers to the above questions, with no success. I've attached the modified beacon sample I've used to test this.

Am I missing some Kconfigs, or is there an updated procedure for setting the public BLE address on the nRF5340?

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.

These additions solved it. Thanks
