How to make DJI spark communicate with pi 3?

Currently, there is no information on whether the DJI Spark will  connect to the Raspberry Pi 3. Of course, it helps to wait for the Spark to be shipped to get a better view on what the product has to offer. We appreciate your interest on this point.

Hi dji mark will Ground station work with Spark.

Ground Station is for more of higher end type systems such as the Phantom and Inspire. Ground Station may at some point be supportive of Spark but not currently. The Pro Ground Station is more for higher end type industrial, farming or industries of that nature. It would not support Spark.
