In android, to receive scan results in the background, the startScan method should be called with a Pending Intent and not a ScanResult

See https://github.com/android/platform-samples/blob/main/samples/connectivity/bluetooth/ble/src/main/java/com/example/platform/connectivity/bluetooth/ble/BLEScanIntentSample.kt#L114-L120 for an official example
