I will forward you the info I found regarding this which I found on the Promark website. Did you download on your smartphone the Promark VR aerial photography app? Then
HOW TO CONNECT
1-Download the Promark VR app for iPhone or Android.
2-Power on the drone.
3-Open the WiFi settings on your phone and connect to “P70-VR” WiFi. Tip: you may need to reset your WiFi by turning it off and then back on again.
4-Once connected, open the Promark VR app and press “Play”
5- For VR streaming, click the “3D” button on the screen and place your phone into the Promark VR 3D Goggles (included in the P70-VR drone).
Shut down the drone and turn it back on if it is still does not show.
Hope it is helpful
