Setting up UART Product hardware configuration

I have a doubt, when setting up the product configuration for a UART type project, I’m asked about data field positions. I require only 2 commands to be sent in form of 1 and 0. How many should I set it to?

Hi @sai.harshitb.24 You may select the number of values you want to send based on the requirement of your project from the dropdown, and you will automatically see them at the right of the screen. Attaching a screenshot of the same.

Just a doubt, the option which asks how often to send data, does it mean it will communicate with the arduino over UART once in 5 mins only?
What is that for though?
