An explanation of how the Epson Moverio FPV Glasses work with the DJI Spark Drone. Since the Spark remote connects to the DJI Go App via Wifi (not USB Cable), you can use the built in Wifi network of the Epson FPV Glasses to connect to the remote. And since the Moverio is just an android device, you can install the DJI Go app.
