Maybe a silly question here.
Flying the Mavic Air with the go 4 app on my iPhone.
Do I need to have the wifi activated on my phone to fly more safely?
Thanks
No you do not - the WiFi connection between the remote and the drone is not like your home WiFi, and has nothing to do with your phone or whatever device you are using to run the app.
Don't be sorry - it is admittedly confusing. The Tello does use the WiFi from your phone because it does not have a dedicated remote control. The DJI remote is what makes the WiFi connection to the drone in the case of the Mavic Air, and it is far more powerful than anything your phone or other mobile device could ever provide, which is how you get 4KM of range vs the 100m or whatever it is on the Tello.
