GeoFence is not working on iOS platform until i turn on the bluetooth on my iPhone device

Hi Ionites,

I have integrated the GeoFence plugin into my application and i receive the push notifications when i am inside the geolocation area with out wanting me to turn on the bluetooth on my android device. But, when i test the same functionality on iOS, i am not getting any push notifications even when i am inside the geolocation area. But i will start getting the push notifications once i turn on the bluetooth on my iPhone device. I am not sure which one is the correct behaviour. Any help in this regard will be very helpful.
