Unknown Command

[lemonpathic]

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?
you can check in details here for the slides I made that address this situation Tello Development - Getting Started
