New GNNS RTK devices

Hello I am interested in adding new GNNS RTK devices.
I am especially interested in cooperation with the iPhone.
Because from what I know, Android devices have the ability to emulate the GPS position in the post.
However, in ios there is only a choice between the original built-in GPS receiver or ViDoc.
As far as I know, other hardware manufacturers such as ArduSimple are ready for integration with their devices.

I’d be interested in that compatibility as well
