Dronelink is a solid app. It will definitely unlock the abilities of your
Mavic Air 2. I have used Dronelink and Litchi and I have to admit that I prefer Dronelink. I think it is a superior product and the Dronelink development teams are spot on with their progress.
It is worth mentioning here that there are some things to keep in the back of you mind when considering this type of app for your drone......
Dronelink IS NOT a replacement for the DJI fly app. If you want to fly your drone manually you should always use the DJI Fly app. Can you manually fly a drone using the Dronelink app, yes you can but that isn't its purpose. The Dronelink app is for flight automation. I like to use Dronelink for the same reason I like to use a 3 axis gimbal with my action camera's. I can walk around an shoot video with out the gimbal all day but it won't be as smooth and as polished as when i use the gimbal. The same is true for the DJI Fly app.. II can fly a missions all day but they will not be as smooth or as polished as they are by automating that same mission in Dronelink.
The
DJI Smart Controller.... This is an interesting use case... The
DJI Smart Controller is a solid device for running the DJI apps and manually controlling the drone. It has a fantastic screen very bright, operates extremely well in direct sunlight and also has active cooling to prevent overheating. I own one and use it with my drones and I like it. That being said the
DJI Smart Controller is an old device (CPU and hardware architecture around 2015) and to use Dronelink with this controller the Google services need to be side-loaded more for authenticating than for Google play functionality. The modern day hardware and OS capabilities and power are beginning to outpace the old
DJI Smart Controller hardware. I have been successful in following the support document from Dronelink (titled: How to Install the native app) and getting the latest version (V2.2.0(2142)) of Dronelink installed on my
DJI Smart Controller. The Dronelink developers have done a fantastic job of porting the app over to this older proprietary android like OS on the
DJI Smart Controller. I haven't done anything real complicated all of the missions I have flown have been simple orbit, fly a waypoint path or just fly to a series of destinations and return home. I am hoping that Dronelink can keep offering compatibility with the
DJI smart Controller but again the technology behind the app may be dependent on power and the underlying ability of the OS and if the OS is old this may not be possible. With that in mind I am also looking to add a more modern controller setup to my toolkit. Like the Default controller for the
Mavic Air 2 plus the TriplTek Sunlight Readable Tablet.
Finally the biggest difference between the Dronelink App and the Litchi App is that the Dronelink app uses 'Virtual Stick technology' and the Litchi app does not. The Litchi app will upload all waypoints to the drone prior to the mission taking place where the Dronelink app will actually send commands to the drone during the flight. Hence the drone and the controller need to stay in constant communication and also my suspicion why the Dronelink app may be better suited for a controller and OS that are more modern with more power and capabilities.
Again Dronelink V2.2.0(2142) is out and does support the
Mavic Air 2. It a fantastic app for automated flights, you will very impressed with it. Good luck and safe flying
