nrf Temp App 2.0. What firmware for chip?

I found several threads with same questions. And also found source codes. But they are too old and require Legacy support for KEIL and old softdevice. Is there actual source code for NRF51822 which uses latest softdevice?

As I know I have to use original Nordic development boards for sniffer. I don't have it. So I can't use sniffer. Isn't it?
