I want to know the meaning of 59ms marked in red in the attached picture, is it connection interval?

This is the approximate advertising interval calculated based on timestamps of received advertising packets.

Mind, that all advertising data are sent on 3 advertising channels few ms apart and it is not said which one has been received in one case. Also, getting Scan Response requires sending Scan Request which also prolongs that. Also, some packets may be missed by the phone.
