Send a list via bluetooth

Hi everyone I have a pizzeria and I created an app to create a list with the customer's order and then I would like to send the list with the order to another app via bluethoot thanks

hi I was able to send and receive the list (List 1) but how can I do after receiving the (list 1) to save it on a (List 2)?
thank you

This may help you. here, list elements is being transfred from screen1 to screen2 and adding to other list. Concept of moving element from one list to other list seems to be equal, here data is shared amongs screens and you are trying to send using BT.
