Yes, i did. The examples i runned given inside this document. 
But receiver just cant get no single packet, using this example. And inside of the app note there are no description about how should i use this examples.

ty for your answer!

Note that the software example referred from the app note (http://www.ti.com/lit/zip/swrc274) is written for CC1200. If you want to use it for CC1120 you have to change the register settings since not all registers on CC1120 and CC1200 are in the same place.

I was trying to change the registers settings for cc1120. Example started to work but i'm receiving about 40% of packets, what registers values should be changed?

I would recommend starting with just sending/ receiving packets to start with (no sniff/ smart preamble). Also, use SmartRF Studio to generate the settings for you. Then when you can start looking into the WOR settings based on the app note.
