Tello edu takeoff problem

[Dennis Wang]

I can use python send command to Tello edu and got ok back, battery? works as well, after I delay 3sec after send "command", I send "takeoff" and got error back, is there something else I should do? such as turn on engine, etc.?

It should work the way you are trying.
I suppose you can fly Tello using your phone app?
My EDU tends to overheat when it is parked. This could be the problem.
What does the LED show?

You can turn the motors on, but this is not necessary.
Spinning propellers prevent Tello from overheating.
You can do it by sending "rc -100 -100 -100 100" (like pushing the right stick down/left and the left stick down/right)

I am having this same issue where functions such as get_battery() and get_barometer() work but takoff() returns an error. any suggestions for next steps?

Brand new drone never flown before?
Tello needs to be "activated" before it can fly. You need the stock app, or TelloFpv (free demo is good enough). I don't think any other 3rd party app can activate.

Now I have the same problem.

I have two Tellos, one EDU and one normal.
I flew them without any problems, did a swarm, and so on. Now, after a longer break, I wanted to fly again.
The normal Tello works, but the EDU doesn't.

In tello3.py I enter command, get OK.
battery? --> I get the value.
takeoff --> error

I wanted to try with the Tello App, do a calibration, but I have a new Android phone and the app is no longer available for Android. I downloaded the apk, but the phone wouldn't let me install it.
