Connection Changed broadcast doesn't work when mobile data is enabled in Marshmallow

Question

I have registered ConnectivityManager.CONNECTIVITY_ACTION to get broadcast when WIFI is connected. It doesn't work when my mobile data is enabled and connected WIFI has no internet connection.

I have created a hotspot in another mobile device which has no internet connection. In my device (Android 6.1) mobile data is enabled. When I try to connect to the hotspot, broadcast doesn't trigger. It works every time when mobile data is disable.

IntentFilter intentFilter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);
registerReceiver(networkStateReceiver, intentFilter);

private BroadcastReceiver networkStateReceiver = new BroadcastReceiver()
{
        public void onReceive(Context context, Intent intentData)
        {
            String action = intentData.getAction();
            Log.e("action",action);
            if (action.equals(ConnectivityManager.CONNECTIVITY_ACTION)){
                // trigger once (when register).
            }
        }
}
