I won’t lie. I LOVE our Air 2S. Have since the day I purchased it launch week.
One of the things I really looked forward to since hearing the leaks back early summer was compatibility with the Mini 3 Pros RC. When It finally happened, I was thoroughly excited and I’m not afraid to admit it.
Anyway, like droneblog’s latest DJI RC and Air 2S Compatibility Explained article points out, I went through every single step in the correct order and my Air 2S worked flawlessly. I burned through quite a lot of batteries the following few days.
But, that happiness would quickly end. Here’s a little story…
Right before a HUGE real estate job (I’m talking all the bells and whistles - Photos, videos, full media kit, travel, etc.), I decided it’d be good to purchase yet another battery for the 2S, as I intended to be on the shoot the entire day.
I dropped the battery in the Air 2S, ran the update, and made sure the camera and all connected (the night before the shoot). Everything looked good. I received the message “cannot take off”, but didn’t think too much of it, as I was in the house with no GPS and it was after midnight…I wasn’t going outside to fly.
The next morning, the morning of the shoot, I loaded up all my equipment, including my Mini 3 Pro and its plethora of regular and plus batteries, as well as our little workhorse, the Air 2S, and its stack of batteries (sans the OG RC-N1 RC) and headed out to the shoot.
I generally get my drone shots first, then shoot interior photos and videos. That day I did the opposite. So, when I went to get the Air 2S up and running, I received the same "cannot take off error. I tapped it and it said error 30064, which points to a software issue. UH-OH. I figured I’d do a compass calibration and then the DJI RC prompted me to calibrate the remote as well. That was different, so I did. Nada. The drone didn’t take off. In the back of my mind, I’m thinking “why-o-why did I not bring the RC-N1”??? Rookie mistake, doh. Anyway, I got the Mini 3 Pro in the air and took all applicable real estate photos and videos as well as area photos and videos.
Sidenote: There will be an article out soon on whether the Mini 3 Pro can be used for professional work. Stay tuned. 
Now, I’m on a mission. I HAVE to get this Air 2S up and running with the DJI RC again, since I really really enjoyed using it. I ran through all of the forums that talked about getting rid of the error 30064. The general consensus was a firmware roll-back and start from scratch. Now, get this, when I wrote the article on “resetting the Mini 3 Pro” I ran through all of the steps in DJI Assitant 2 on how to roll back the firmware. My Air 2S, a few weeks ago, indeed had 2 or 3 previous firmware versions. Fast forward to this week and THEY WERE ALL GONE. The only firmware was the current one and I couldn’t even refresh it.
It got me thinking for a bit, so I relinked the Air 2S to the RC-N1 (which I actually like) and I flew a 1/2 battery. I then thought, just MAYBE, it’d be a good idea to relink the DJI RC to the Air 2S and see if I could perhaps get a firmware message (either inconsistent firmware or something). I didn’t know what to expect.
Lo and behold, I relink/pair the Air 2S to the DJI RC and everything worked. No more error code. I flew down the battery and then proceeded to put every single Air 2S battery I have in and fly them for a few minutes each. They all worked and had no issues whatsoever.
I don’t know what the disconnect was, but the fix was as simple as a relink. DOH.
TL:DR - If you have new batteries bought after the newest firmware update for the Air 2S AND you are using a DJI RC and receive the dreaded error 30064 “cannot take off”, simply relink your Air 2S to your old RC-N1, then repair the Air 2S to your DJI RC. It SHOULD work like a charm…
