No bluetooth devices found

I am using the IONIC framework to build an application for iOS.
I am using the com.megster.cordova.bluetoothserial plugin.
The application is working fine on android but not on iOS.
When I try to do a scan it doesn’t see any devices - not even my samsung note 4.
I tried to debug this through Xcode and it returns the below message.

List of currently known peripherals :

I built the app using ionic and then opened Xcode to create the archive and then uploaded it through the devices to my iPad. Is there anything I am missing, which would cause the app to not find any devices?

Thanks a lot.

Hi,

I’m trying just to get this running on android but kinda lost.

Could you please assist in an example of getting started?

Thank you
