Question 
My Tello EDU Drone automatically shut off after a few minutes. I restarted the drone, but now it doesn't recognize my program is running in Scratch. 
 

Answer

Identify the Issue

When the Tello EDU Drone automatically powers down, it will lose the Wi-Fi connection and will need to be connected again. 
 
Recommended Solution 
Go to the task manager, and click on your network connections icon. In the pop-up window, click Connect on the Tello-######. You will see a secured connection next to the Tello drone name when it's reconnected to Wi-Fi. 
 
If this doesn't work, get the communication back by running the tello.js command. The following steps need to be done: 

1. Disconnect the drone from the Wi-Fi. 

2. In the Windows search box, type in CMD to open a Command Prompt window. 

3. Navigate to the Scratch folder location. 

4. Type Node Tello.js in the Command Prompt window and press Enter. 

5. Reconnect the drone to your Wi-Fi. 

6. Run your program in Scratch.
