SDK: 3.1.0
Hi,
I am trying to setup my low power preipheral with a new ble address via bt_id_create.
Everthing works fine when I use the exact code from the ble fundementals course l2/l2_e3_sol.
To enable low power features like bonding and direct advertising I copied the kconfig from this sample https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/bluetooth/direct_adv
Due to the
CONFIG_BT_SETTINGS=y CONFIG_SETTINGS=y
I have to call settings_load(); I think at least and than init the ble stack.
But after that the address creation failes with err -12
Any idea how this could be handled?
See the code and the config below:
