regarding "ble_app_hrs_rscs_relay"

Question

Hi.
I'm using PCA10028, SDK10.0.0 S130. 
 I think "ble_app_hrs_rscs_relay" provides Central function and Peripheral function.
So it should be advertising right after running program. 
 I just added code as below to get bd address of nRF51 on PCA10028 board. 
 int main(void)
{ 
 ...... 
 ble_gap_addr_t addr;
ble_gap_addr_t * p_addr = &addr;
err_code = sd_ble_gap_address_get(p_addr);
if(err_code==0){
	printf("address :");
}
int i;
for(i=0;i<6;i++)
{
	printf(" %x", p_addr->addr[i]);
}
printf("
");
 
 ......
} 
 It returns "90 ee 62 e8 c7 f9", but I can't find this bd address at Cetral device.
I'm sure the Central Device is OK because it shows me other device's bd address. 
 Is this sample code advertising?
I hope your reply.

The advertised MAC address is the device address stored in NRF_FICR->DEVICEADDR[], this post explains how to retrieve the BLE address from NRF_FICR->DEVICEADDR[] and how it is generated. 
 Update 09.03.16: The application will start to scan and advertise immediately when running the example, see main(): 
 int main(void)
{
 ...
 ...
 /** Start scanning for peripherals and initiate connection to devices which
 * advertise Heart Rate or Running speed and cadence UUIDs. */
 scan_start();

 // Turn on the LED to signal scanning.
 LEDS_ON(CENTRAL_SCANNING_LED);

 // Start advertising.
 err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
 APP_ERROR_CHECK(err_code);

 for (;;)
 {
 // Wait for BLE events.
 power_manage();
 }
}
