- Background service is running in our application which contains BLEScanner to scan RSSI for connected device. When Mobile device screen gets turn off it is suspending BLEScanner and application is not receiving Scan Results in callback.
Please let us know if more information required.

We don't stop filtered scans. Allowsing non-filtered scans was badly impacting battery.
See ScanManager.java file for defails:
void handleSuspendScans() {
for (ScanClient client : mRegularScanClients) {
if (!mScanNative.isOpportunisticScanClient(client) && (client.filters == null
|| client.filters.isEmpty())) {
/*Suspend unfiltered scans*/
if (client.stats != null) {
client.stats.recordScanSuspend(client.scannerId);
}
handleStopScan(client);
mSuspendedScanClients.add(client);
}
}
}

Hi,
I have below queries...
1. This is similar to the GPS and we think this should be a user acceptable case like GPS
2. Is there any alternatives ?
Please let us know.

Description
BLE scanner does not work in our application in Android 8.1 release, if Phone display is turned off.
Same BLE scanner works with Android 8.0 release.
Expected Application behavior:
We are using BLE Scanner in our application to detect the proximity of the devices.
We need to continuously check the proximity (RSSI values) even if phone display is turned off.
References:
In below source code of Android 8.1
Display Listener mDisplayListener is used onDisplayChanged() function checks is screen status and if it is OFF then BLE Scans are suspended.
public void onDisplayChanged(int displayId) {
if (isScreenOn()) {
sendMessage(MSG_RESUME_SCANS, null);
} else {
sendMessage(MSG_SUSPEND_SCANS, null);
}
}
Questions/Alternatives?:
1. Is there any way to get the continues RSSI values even if display of the phone if OFF?
2. Can we override this behavior in any way?
3. Is there any other alternative way to detect the proximity of the device?
Thanks,
Lokesh
