Error 515: Not connected to a Bluetooth Device


I am controlling an Arduino through App Inventor 2. I setup 2 screens with the Bluetooth parameters selected on screen 1.
All buttons and feedback work correctly on screen 1, but when I change to screen 2 I receive the Error 515 message and
no communications take place. When I change back to screen 1, normal communications are restored. Any ideas?

for bluetooth I recommend you to use only one screen

to simulate different screens, just use vertical screen arrangements and set them to visible = false or true as needed

  1. You should use an error handling event and set the action for that particular message.
