Apple Pencil 2 connect to iPad gen 7
How do you connect an Apple Pencil 2 to an iPad generation 7 iPad?
iPad, iPadOS 14
You don't.
You need to be using the original, 1st generation Apple Pencil with the chromed top cap with Lightning connector protective magnetic cap.
Return that Apple Pencil 2 and purchase the Apple Pencil 1, instead.
Best of Luck to You!
