How to scan and get list of nearby discoverable mobile devices?

[VIJAY]

Hi,

I am using 

I am able to list BLE devices using the below example.

SDK = nRF5_SDK_15.3.0_59ac345,

Example : nRF5_SDK_15.3.0_59ac345\examples\ble_central\ble_app_gatts

I have just added one case in "ble_evt_handler" this function.

                NRF_LOG_RAW_INFO("\n");
              }
            }
         }
         break;

But not be able to scan mobile devices which are discoverable in other mobiles.

 

So, Guide me to scan nearby mobile devices. What change I should make in the above example?

If any other suggestion, Guide us.

Thanks.
