CCS/CC2650: How can add MAC address of some devices to the whitelist

Tool/software: Code Composer Studio

Hi,

I have some CC2650 sensor tag, and I want they only recognize each other, so I add their MAC address to the Whitelist as follow(in multi_role_init  function):

        uint8_t bdAddr[][6] = { 0x98, 0x07, 0x2D, 0x35, 0xA4, 0x02,      //Mac Address: 0x98:0x07:2D:35:A4:02
                    0x98, 0x07, 0x2D, 0x1D, 0x3F, 0x06,   //Mac Address:98:07:2D:1D:3F:06
                    0x24, 0x71, 0x98, 0xCF, 0x7E, 0x06,     //Mac Address:24:71:98:CF:7E:06 
                    0x54, 0x6C, 0x0E, 0x80, 0xB3, 0x01,      //Mac Address:54:6C:0E:80:B3:01
                    };
             

          

               HCI_LE_ClearWhiteListCmd();
               HCI_LE_AddWhiteListCmd(HCI_PUBLIC_DEVICE_ADDRESS, &bdAddr[0][0]);
               HCI_LE_AddWhiteListCmd(HCI_PUBLIC_DEVICE_ADDRESS, &bdAddr[1][0]);
               HCI_LE_AddWhiteListCmd(HCI_PUBLIC_DEVICE_ADDRESS, &bdAddr[2][0]);
               HCI_LE_AddWhiteListCmd(HCI_PUBLIC_DEVICE_ADDRESS, &bdAddr[3][0]);
         

But, unfortunately, it does not work, and nodes cannot recognize other nodes in the whitelist. Could you please guide me how can fix it?
