Scanned BLE addresses print on comm port

Question

Hi, 
 I am using nrf52840 S140 PCA10056 SDK 15.2.0 version with example ble_app_multirole_lesc_S140_PCA10056 . i am using Segger Embedded studio IDE. So now problemis i am not able to retrieve the scanned device addresses . I want to retrieve the surrounding device addresses printed on comm port. Could any one tell me which function does that ? and where do i need to change in this example.

Hi, 
 The example use the BLE scanner module with filtering, to only search for devices that match a given name, or includes the HRS UUID. To see any devices, you will have to disable filtering, by removing the following lines from scan_init(): 
 if (strlen(m_target_periph_name) != 0)
{
 err_code = nrf_ble_scan_filter_set(&m_scan, 
 SCAN_NAME_FILTER, 
 m_target_periph_name);
 APP_ERROR_CHECK(err_code);
}

err_code = nrf_ble_scan_filter_set(&m_scan, 
 SCAN_UUID_FILTER, 
 &target_uuid);
APP_ERROR_CHECK(err_code);

err_code = nrf_ble_scan_filters_enable(&m_scan, 
 NRF_BLE_SCAN_NAME_FILTER | NRF_BLE_SCAN_UUID_FILTER, 
 false);
APP_ERROR_CHECK(err_code); 
 You can the add a case to print the address to the log in scan_evt_handler(): 
 case NRF_BLE_SCAN_EVT_NOT_FOUND:
{
 NRF_LOG_INFO("Received adv from: %02x:%02x:%02x:%02x:%02x:%02x",p_scan_evt->params.p_not_found->peer_addr.addr[0],
 p_scan_evt->params.p_not_found->peer_addr.addr[1],
 p_scan_evt->params.p_not_found->peer_addr.addr[2],
 p_scan_evt->params.p_not_found->peer_addr.addr[3],
 p_scan_evt->params.p_not_found->peer_addr.addr[4],
 p_scan_evt->params.p_not_found->peer_addr.addr[5]);
} break;
 
 Best regards, Jørgen
