Bluetooth connection problems when switching screens

Hi everyone! I am developing an application with an ESP32, in which I send temperature data via Bluetooth, so that the application shows these values ​​on a graph. However, I am having connection problems when switching screens. Whenever I connect to my ESP32 and change the screen, my device loses the Bluetooth connection. Would you be able to help me resolve this problem?

Switching Screens stops one program and starts another.

That breaks Bluetooth connections.

Instead of multiple Screens, stack Vertical Arrangements in Screen1, only one of them .Visible at a time.

Right! Thank you very much for the immediate response.
