Problem with tello

Hello everyone!
I have a problem with my tello that I already use well and with the new one of the boost combo type! Both don’t work for me; It will be an update problem, from the fornicer or from the manufacturer, or what, I don’t know. Install the usual libraries well. Can someone tell me what’s going on?

Thank you so much

What firmware version are you using and what is the specific problem you’re running into? Does the Tello respond to the Takeoff command and ignore others?
