I am trying to send streamoff and streamon to my tello, but am always greeted with "
Send command: streamoff
Response: b'Unkown Command!'"

I know I am connected to the drone because I am able to get the battery data

Have you send "command" msg before sending "streamon" msg to Tello?

Again,. thank you for your good work. u would like permission to use some of your charts for our educational materials that we publish to mentor STEM/STEAM students in drones. The flow charts help them understand this complex communication system. Thank you.
