I've built a Xamarin app that listens to GPS devices for NMEA messages. It works in UWP, and now I want to get it to work with iOS.
For UWP I use the NMEAParser project from here: https://github.com/dotMorten/NmeaParser . That seems to work fine for UWP, and it lists "Xamarin (Android + iOS)" on its specs, but attempting to use it for IOS gives me no joy, the NmeaDevice class doesn't seem to exist for iOS, and the other classes behave similarly.
Is there a similar thing for iOS? That is, a component that will allow me to plug a GPS device (I'm currently using an XGPS160, as well as a Trimble R3) into an ipad and listen for its NMEA messages?
