How can the cloud platform obtain real-time flight status, GPS and other data of the aircraft?

sean

These data are in the OSD topic.

topic: thing/product/{aircraft or remote control sn}/osd
As long as pilot 2 APP successfully access to the cloud, the aircraft will continue to push the osd topic, and the backend can receive the data by subscribing to this topic.
For the parameters pushed in OSD, you can find the corresponding description in the aircraft properties.
