Constant sensor error when starting

[kennethone]

Just bought a tello, getting "sensor error" warjing constantly when starting on flat ground. If I recalibrate it goes away but comes back in on next restart. Sometimes if I reset it goes away. But it's there almost consistently. Can I disable it and still fly somehow? Is there a better app which will ignore this error?

I never had this problem so don't know the cause and can't help.
But I know that no app can clear this error.
