I am trying to obtain the GPS coordinates from the flight controller to use on an onboard external computer. I have been successful at using the Assistant 2 software to set the GPS out to 1HZ, and being able to view the raw data (with a fixed number of bytes) coming out of the API port. While reading through all the documentation for the OPEN protocol in order to parse the data, it states that the documentation is only applicable for the M100. When I contacted DJI about this, they stated that the A3 output messages are proprietary. This is frustrating because I am so close to obtaining the information I need, yet have no way of correctly parsing the data. Instead, it sounds like I actually have to write code through the onboard SDK to output the generic GPS coordinates, which seems like a lot of work.
Has anyone been able to parse the messages coming from the A3 controller or have any solutions for getting the GPS coordinates from the controller?
