1, PC connection TELLO EDU sends command and acceptance response

Power up TELLO EDU, at which time the status indicator of the plane is displayed-> Yellow flash

Yellow flash indicates remote control signal interruption

At this point, connect the PC on the TELLO EDU, as follows:

When the PC is connected to WiFi, the state of the aircraft is still yellow flash.

At this point, you can operate the TELLO, and the input command will appear as follows, where OK appears, that is, the connection is normal.

Enter other instructions to complete the flight control of TELLO, such as:

For specific instructions, please refer to "TELLO_SDK_2.0_.nd instructions .pdf"

2, PC connection TELLO EDU accepting state

At this point, in the TELLO3.py file, the port will be changed to 8890, and the status information of TELLO will be automatically received after running the program.

The meaning of each parameter is seen "TELLO_SDK_2.0_ User Instructions.pdf"
