There is an interesting note in the Multi-Tello-Formation flying README. In particular number 5 in the README.

Looking through the code, it looks like if you send "Re <command>" via UDP that you get "Re" back with something after it. I didn't see this in the SDK 2.0 documentation. Does anyone know how to make the commands reliable over UDP? Does the drone respond with a sequence number? I think this is what this line does, but am not sure:


Thanks in advance.

I don't know the SDK so I can only guess:
RE stands for repeat, and Tello commands are re-entrant. That is a command is repeatedly sent with the same unique sequence number and Tello simply ignores commands with seq IDs it has already executed.
