Question

What do the colors of the Aircraft Status Indicator light mean?

Answer

Normal State (Not Charging)

• Green (2x) and video within the Tello app: indicates the drone has successfully connected to a device via Wi-Fi (video positioning available)
• Flashing Yellow: indicates the drone is searching for a connection to a device (video positioning unavailable)
• Flashing Multicolor: indicates startup; this is performing a self-diagnostic test

Charging State

• Solid Blue: indicates a full charge when the drone is plugged in and being charged by a micro USB charger (LED should first blink fast 1x green and then 3x red)
• Flashing Blue: indicates a charge is in process when the drone is plugged in and being charged by a micro USB charger
• Flashing Blue (7x quickly + 1x long): indicates defective battery
• Flashing Yellow and video within the Tello app: indicates the drone has successfully connected to a device via Wi-Fi and video is available within the app
• Flashing Multicolor: indicates startup; this is performing a self-diagnostic test

Warning State (While in Use)

• Yellow Flashing: indicates remote control signal lost (need to reconnect)
• Red Flashing Slowly: indicates low battery
• Red Flashing Quickly: indicates critically low battery (near 0%)
• Solid Red: indicates critical error (such as navigation system error, aircraft tilt); need to restart and reconnect the drone and app. If problem persists, you might need to perform a hard reset and update firmware.

Additional Comments
