It is not possible for the peripheral to tell the centrals that the old advertising name is invalid no.

If you are using random resolvable address (and you haven't bonded with the smart phones) the smart phones shouldn't be able to recognize that the advertisements come from the same device. Have you tried this?

I would also recommend using nRF Connect for PC, or even better, a sniffer to see what is actually in the advertisements.

I have tested with several android and ios smart devices... And yes I also think that this could be cache problem... is there any option to somehow tell centrals that this name is not valid anymore? maybe for each switch of advertising mode I manually set device name to "n/a" and actual name?

I have noticed also some other interesting behaviour... in your nrf connect app on some of non paired smart devices sometimes are found and sometimes are not found.... While on paired device is my peripheral which is advertising with whitelist and fp set to both, shows up really fast

That doesn't make much sense. How would the unknown centrals get the advertising name if it isn't included in the advertisement? What kind of centrals are you testing with? Could it be a cache problem?
