iOS cordova app for QLN-420 printer


I am working on an for iOS, it is a cordova based mobile app. The android version was developed prior to my involvement. We are connecting to the QLN-420 printer via bluetooth. I am seeing info on android and windows development here but nothing for iOS. Was looking for some info to get started developing a plugin for iOS to use bluetooth to communicate with the printer. Any help is appreciated. Thank you
