find3-android-scanner WiFi scan throttling limitations

https://developer.android.com/guide/topics/connectivity/wifi-scan#wifi-scan-throttling

The following limitations apply to the frequency of scans using WifiManager.startScan(). Android 8.0 and Android 8.1: Each background app can scan one time in a 30-minute period. Android 9: Each foreground app can scan four times in a 2-minute period. This allows for a burst of scans in a short time. All background apps combined can scan one time in a 30-minute period. Android 10 and higher: The same throttling limits from Android 9 apply. There is a new developer option to toggle the throttling off for local testing (under Developer Options > Networking > Wi-Fi scan throttling).

On Android 9 having a foreground service is not enough. This is going to be tough. I'll investigate alternatives (even strong one, such as something with root :skull_and_crossbones: ).

So far I couldn't find anything useful. It seems the only ways are patching the OS or keep the screen on as the app does right now. :sob:

Hi, I disabled WiFi scan throttling in my Samsung A10 (Android 10) already. The screen is ON. The app is slow to push the learning data. Few data (5 datasets?) every five minutes.

If I use the ESPClient, I can submit every 5 seconds. Is it normal and expected?

Thanks a lot.
