Good evening, I created an app that with buttons sends command SMS to a LILYGO card with SIM. This card then sends a return feedback to the app that is displayed. The question is this: is it possible to make a waiting message appear on the app after pressing the button and until it receives the return feedback? Thanks
Set a message on a label when you send the command, remove the message when the response is received.
If you want to prevent interaction with the app until the response is received, use the notifier progress dialog.
