Hope I am not just late to the party with this one.
Be aware that the latest DJI firmware for the Air2S appears to break Litchi, Maven and Dronelink.
Firmware version v02.04.23.20
I think there was another firmware update just after that, but it didn’t resolve the issue.
The issue presents as this.
Upon completion of the firmware update when you try to take off, you will get an “Unknown error (code: 180)”. This means you can not take off at all with any of these third-party apps and I don’t think either DJI or Litchi know what is causing the problem. There’s certainly no mention of a fix at the present time.
The most up to date information from the Litchi forums is here;
Air 2S Firmware 2022-10-26 Error
Luckily I spotted this before going flying today. As soon as I turned on my Air2S I got the new firmware notification, but have not installed it. I won’t until I start seeing people talking about a working bugfix.
