Hello, i have another problem. If i click on the notification Screen1 opens and then the virtual screen "ScreenVerlauf" opens. So far so good. But the listview is empty and the buttons dont work.
I think that is has to do with your if block, the If: Get(global BT_Data) = (P), because your list appears empty. you might have had an error there or at any block designed to set Bt_Data.
What's up with your transparent backgrounds (PNGs)? I don't see any point in them. Besides, they crash the app (at least on the Google Pixel 7 Pro, Android 15 with Companion).
Apart from that, you have to request the Android version-dependent BT permissions. This issue has been discussed hundreds of times in the forum over the past few years and conclusively resolved, not least by me. → Bluetooth liste of devices deosn't work anymore - #7 by Anke
I got no problems with connection or sending/receiving data. My problem is when i click the notification it opens screen1 and then set the visibility of a VerticalArrangement (called "ScreenVerlauf") to true. But then it feels like the screen is static because the buttons dont work and there are no entries in the listview even there where entries beforehand.
As I said, your app doesn't run with either the companion app or the APK (Android 9, 15). The app crashes or won't even start. Before we continue, first make sure your app can even start.
