Tello Platform Set Up (1 Hour)

Charge the Drone

First we need to make sure our drones are charged. Follow the directions below to get your drone charged up.

1. Insert the battery (with the tab facing upwards) and slide it in from the back of the drone as shown below.


2. Charge via the micro USB port on the side as shown below.

3. On the front of the drone, to the right of the camera, is the drone status indicator LED shown below.

4. On the opposite side of the micro USB port is the power button shown below. To turn the drone on press this button firmly once. Repeat to turn the drone off. 

5. On the underside of the drone are the vision and position sensors shown below.

6. Charge your drone by ensuring that the power is off and your micro USB cable is fully plugged in. The LED on the front will slowly blink blue and will switch to solid blue when fully charged as shown below.

Connecting Your Drone

Tello can be operated with DroneBlocks by launching a pre-programmed mission or by selecting one command black at a time, beginning with the takeoff block. For the lengthier challenges towards the end of this curriculum, it is best the mission be programmed before powering on Tello and connecting via the hotspot. This is recommended to allow for optimal flight time because each battery allows for approximately 13 minutes of flight time. Programming and troubleshooting mission code before connecting provides more power for flight!

Follow these instructions precisely to properly connect to Tello. Steps for iOS, Android, and laptops using the Chrome App are outlined here. A downloadable PDF for quick reference is also included.
