All this Wifi handling is a PITA.
Thats why I would recommend to get a cheap used phone as a dedicated flight controller. There are so many used phones with minor defects available on ebay for little money that we can just bring to another life. Who needs a SIM card slot to fly Tello? Or a broken home button (there's always a "home button" app to replace it)? You can also do with a broken front facing camera, but the main camera should work.
