Sniffing with the nRF52840 dongle

Can the nRF52840 dongle be used to sniff/record BLE communications even if the recorded packets cannot be decrypted, or can it only record packets when decryption is possible (have the required TK and pairing method)?

It's only really able to record packets when decryption is possible, the main reason is that the link will very likely change the connection parameters or hopping sequence, and without decryption the sniffer will not be able to receive the change.
