BLE Extension in Android 11

Hi, I didn’t find a topic about it so I come here to talk.

I made an application using the BLE extension, but on devices with Android above version 10 it hasn’t worked, has anyone gone through the same or has some other BLE extension?!

What exactly does not work?
Which version of the BLE extension are you using?
As always it might help to do a search in the communities…
