When I use the list viewer to get my scanned items, there is always many empty slots between each item. How do I solve this?
You can use the replace all Text block to replace [newline] with an empty string (“”):
If you need help with that, post a screenshot of the blocks you’re using to get scanned items.
I did that, but then, say the device name was ‘esp32’, the layout will be like the following:
e
s
p
3
2
Do you mind sharing the solution so other people who read this topic later will know?
