The documentation here:
https://docs.zephyrproject.org/apidoc/latest/group__bt__gap.html#gae11eb8ad254418c38a0e8689df25a159
says, I can call l bt_id_create() before bt_enable(). I tried it like this:
uint8_t irk[16] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 };
int err = bt_id_create(BT_ADDR_LE_ANY, irk);
if (err < 0) {
LOG_ERROR("bt_id_create failed (err %d)", err);
}
and I get a -22 as the error code. Do I call the function with the right arguments, and what does error -22 mean? I guess it is EINVAL, but I don't see any invalid argument.
So I tried to call it after bt_enable(). This resulted in a log message like this:
[00:00:11.336,578] <inf> bt_hci_core: Identity: 00:00:00:00:00:00 (public)
and obviously any call to other functions, like start advertise, doesn't work anymore, because it is an invalid BLE address.
So finally I called bt_id_create() in the ble_ready callback, before the settings_load() call. This seems to work, I get a random BLE address.
But "bt show-id" shows always the same address (after reset). I set CONFIG_BT_RPA_TIMEOUT to 60, looks like it is ignored. But after reset, I get a new BLE address, so seems to work in general, just the automatic change doesn't work. How can I fix this?
