Bluetooth and screen

Hello I have a problem with bluetooth, I have a main screen where I activate the bluetooth after I go back to go to a second screen to send codes with bluetooth but the bluetooth are disactivates I would like to know if there is a solution?

The bluetooth connection does not work across screens.

Use virtual screens on Screen1 to maintain your connection across “views”

Use different screens wisely

If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a while...
