Hi Ariel66, thanks for contributing to the forum. I am very familiar with this controller issue! You can try to link the controller manually.
First, turn your drone upside down and look for a little recessed button. Take note where it is. Find something small enough to be able to push that button
Turn on both the controller and the drone.
Wait about a minute to make sure they are all powered up and pick up your drone and push that recessed button for 2 seconds. The button will start to blink red.
Now take your camera dial, the gimble dial to the far left. Flip the S2 switch a few times. The controller will start to beep after it begins linking.
Hope that works well for you,
