To provide the Tello app data so we can check what happened during your flight. The flight controller data cannot be stored on the aircraft and will be sent to the Tello app in real-time. The simplified flight controller data will be saved in the Tello app and can be exported by connecting the mobile device to the computer. At most 2 GB data can be stored in the Tello app. If the storage is full, and you continued to fly the aircraft, the oldest data will be overwritten. All 2GB of data can be exported from the app file where it is saved and may be lost after the app is uninstalled.
For the oldest version of the Tello app; the data cannot be sent back to the app. Check whether your app version is 1.2.1 for Android or later, or 1.1.2 for iOS or later. If yes, do export data in the following paths:
If you are using Android: File Management/Local/SD Card/Android/data/com.ryzerobotics.tello/files/droneLog/ If you are using iOS: File Sharing/Tello/log
