nRF9160 DK lte_ble_gateway sample to get beacon UUID

       I am working on nRF9160DK lte_ble_gateway sample, in that I want to scan for beacons UUID and major, minor value.
       nRF52 device is programmed with bluetooth HCI (UART). I dont want to use BLE scan filters.

      Could someone please provide me a sample or hint on how to get it.
