I have a background Android Service that's purpose is to communicate with another device (non-phone) using a Bluetooth socket. Everything works fine except that the service gets stopped and restarted by the OS when the phone display is sleeping. This restart sometimes leaves a 15-20 minute gaps where there is no communication between the Service and the Bluetooth device and I need to be able to query the device every minute. Is startForeground the proper approach?

Attempted to use:

startForeground(int, Notification) //still see gaps when phone sleeps

Service:

 public class ForegroundBluetoothService extends Service{
        private boolean isStarted = false;



        @Override
        public void onDestroy() {
            super.onDestroy();
            stop();
        }


        /**
         * @see android.app.Service#onBind(android.content.Intent)
         */
        @Override
        public IBinder onBind(Intent intent) {
            return null;
        }


        /**
         * @see android.app.Service#onStartCommand(android.content.Intent, int, int)
         */
        @Override
        public int onStartCommand(Intent intent, int flags, int startId) {
            loadServiceInForeground();
            return(START_STICKY);
        }

    private void loadServiceInForeground() {
        if (!isStarted) {
            isStarted=true;
            Notification notification = new Notification(R.drawable.icon, "Service is Running...", System.currentTimeMillis());
            Intent notificationIntent = new Intent(this, MainScreen.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
            notification.setLatestEventInfo(this, "Notification Title",
                "Service is Running...", pendingIntent);
            startForeground(12345, notification);
            try{
                queryTheBluetoothDevice();

            } catch(Exception ex){
                ex.printStackTrace();
            }
        }
     }

    private void stop() {
        if (isStarted) {

            isStarted=false;
            stopForeground(true);
        }
      }
 }
