nrf51822 read id connection device

[Ivan]

My question may seem silly, I did not so long ago been programming NRF51822 S130. I use examples experimental_ble_app_blinki. I want to get the module ID smartphone when connected. There is such a function?

I need to get the ID by the device itself. It is necessary to create a white list of smartphones in the chip. Promotional package with an ID has been the solution of problem. But it can be vulnerable to security.
