Posted on January 13, 2016 at 10:38Dear Customer,
Using the BlueNRG-MS, the static random address is stored inside the Flash. The address is loaded when doing ACI_GAP_INIT. Hence, to overwrite the static random address the HCI_LE_SET_RANDOM_ADDRESS must be called after ACI_GAP_INIT.
To read the random address, you have to use the command:
ACI_HAL_READ_CONFIG_DATA (Offset=0x80).
To do this, It nedded to download the latest version of GUI DK.
N.B.: the HCI_READ_BD_ADDR command reads the Public Device Address.

How do I set a true random address?
Using
hci_le_set_random_address
() I get 0xFF FF FF FF FF FF.
Hardware is Nucleo-L053R8 & IDB05A1
Also setting a Beacon with BlueNRG GUI v1.8.0 with a random address also results in a address of 0xFF * 6
Following is the code I tried:-
uint8_t RANDOM_BDADDR[] = {0x55, 0xaa, 0x55, 0xaa, 0x55, 0xaa};
uint8_t bdaddr[BDADDR_SIZE];
uint8_t stack_mode = 4;
BlueNRG_RST();
ret = aci_hal_write_config_data(CONFIG_DATA_ROLE,CONFIG_DATA_ROLE_LEN,stack_mode);
ret = hci_le_set_random_address(RANDOM_BDADDR));
ret = hci_read_bd_addr(bdaddr);
//
bdaddr = 0xFF FF FF FF FF FF !?!
