How to use share components in different screen?

[ShunFan_Yang]

Hi, all,
I have created an BLE extension module and draw it my "Screen1" page.
When BLE is connected, I will switch to "Screen2".
However, I can not use BLE blocks in Screen2.
If I draw another BLE component in "Screen2" again, it will be seem as different components.
Thus, when I use "WriteBytes" block, it inform me the BLE device is not connected.(due to they are different)

Does any how to achieve share components resource in different screen?
Best Regards,
Fan

Bluetooth will disconnect when you switch to another screen.

Use virtual screens instead

Use different screens wisely

• Before starting to create another screen, first you should think about is it really necessary? 
• See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed... 
• See also Martyn_HK's example about how to use Tabs in App Inventor and another example from Cyd. and my Tabbed Screens Demo

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