Hello there.

For braille, the at sign or @ is, space with u then dot 4. Good luck & hope this helps.

It will be your dot 4 with something else.
on my braillesense u2 it is dots 7 and 4 together. dot 7 is the backspace key.
That's in 8-dot braille input mode.

Try dot 4 with other keys like shift or backspace.
There's a lot to learn for sure.
