DJI Goggles 3 supports live feed sharing via Wi-Fi. You can share the live feed to the DJI Fly app over Wi-Fi and enable live streaming within the app.
Some countries and regions prohibit the use of the 5.1GHz or 5.8GHz frequency band, or both. In some countries and regions, the 5.1GHz frequency is only allowed for indoor use. If the 5.1/5.8GHz frequency band is unavailable (such as in Japan), screen sharing to a smartphone via Wi-Fi is unavailable. To achieve screen sharing, a wired connection is recommended. Before flying, make sure to check and comply with local regulations.
