A1 is dribbling up the court, drives to the basket for a layup, takes his permitted step, while airborne decides not to shoot (or pass) and lets the ball fall to the floor directly in front of him. Ball bounces on the floor, A1 returns to the floor (not really sure which happened first), and A1 then gathers the ball without it having been touched by any other player. Is this an illegal dribble violation or a travel violation?

Thanks.
