Hi there, Thanks you for reaching and sorry for some inconvenience that you have faced, regarding with your concern when using the Sport make sure to turn off first the Beginner mode then on the Remote toggle the switch to Sport mode, but keep on mind when using the Sport mode all sensor will be disabled.

I forgot to mention that when I activated the dron I did not have the remote controller yet  I did it just with my cell phone. So I wonder if I had to follow a particular procedure to deactivate the settings for a wifi connection and then begin to use it with the remote controller.

Yes, you can deactivate the mobile link and activate the RC link by a combination movement from power switch of the SPARK. Please proceed to the relevant page in the instruction manual supplied with the drone.
Observe all safety precautions while doing this operation especially keeping the RC away from the SPARK. .
