FlightAware ProStick to GDL90 data stream

I am looking for a way to get ADSB-IN to my motorglider and into Ozrunways on an iPad so I have traffic awareness in flight. Ozrunways can accept a GDL90 data steam (Garmin format I believe).

I can use a uAvionics pingUSB but that requires taking over the wifi on the iPad, so I loose my hotspot connection to my phone. (Phone is the hotspot).

I am looking if there is a way to use a ProStick to provide a GDL90 data stream to the iPad, probably plugging it in to a small Pi or arduino and supplying the data stream via the new device connecting to my phone hotpot as a client, or bluetooth or USB?

You may want to look into stratux (stratux.me) as I think that generates GDL-90
