don't know if this helps but i just having this issue on SM-991N, the scan results doesn't return anything, but on xiaomi 12T, it's fine, i can stream data from the flutter_foreground_task to the main ui thread

as a specialization, not only in the background, in the background and switched off screen

This is how i do it:

• Request ignore battery optimization
• in android manifest, request the type of service of your case
• use the flutter_foreground_task, have the FlutterBluePlus instance in the TaskHanler itself, not from the main UI thread

My project is private so i can't provide code but i will make an example if i have time

@TheValkDokk I am working on a project that desperately needs this, Can I reach out to buy directly for a quick conversation on the topic. I could pay you for your time if need be. My company attempted to contract the owner of this package for support on this but he could not deliver on the contract. You might be a better resource.

On android scanning only works in doze mode if the service is scanning for a specific mac-address or ServiceUUID, otherwise it returns empty. On iOS you need to scan for specific ServiceUUIDs as well. In terms of scanning for all advertising devices i have no found a solution.

You mentioned in the other post that you added a lot of debug information to find where the lib was stopping. Any further luck with that? Were you able to override something?
