Feature Request : DJI Pilot 2 - Basic Readonly API

[dariofil-star]

Hi,

We have a business requirement to obtain GPS position of drone. Currently it is very complex/complicated to do this via CloudAPI.

It would be of benefit to many if the DJI Pilot 2 app exposed a simple output of this information every few seconds. Lat, Long, Battery %, Speed

Just a few read only parrameters that we can use for simple integration to represent the drones on the map.

You can get that information from the device_osd event
