It can be hard to users to find out that they have deactivated Bluetooth, if their notification is
minimized / collapsed. They would need to open the app to find out, something is wrong.
I'd suggerst to push a separate error message when Bluetooth is deactivated, or change the notification symbol and display an exclamation mark or cross-out the symbol.
This is actually and issue of the https://github.com/DP-3T/dp3t-sdk-android and has been fixed in the SDK. The new sdk version will be included in the demo app soon!
