I'm using the following method from BLE scanner API on Android 8+ to scan for BLE Beacons
startScan(List<ScanFilter> filters, ScanSettings settings,
PendingIntent callbackIntent)
The problem is that after sometimes I can see Scan Logs but nothing is delivered by the callbackIntent any idea why is this happening?
This is the expected behavior on Android 8+. if you need to scan continuously a periodic mechanism is needed in this case. For more information about scanning on different Android versions and different ways. Have a look here
