I don't know how your camera does it, but I've recently tried connecting my NX300M to my iPad, and this is what I had to do:
Initiate a wireless network from the camera by pressing the direct connection button
Find the network name among the wireless networks detected by your iPad and connect to it
Confirm the connection on the camera
Open the Smart Camera app on your iPad
Proceed from there.
Hopefully this will work for your camera too. There may be a different method for creating a wireless network on your camera instead of pressing a dedicated button, by going through the menu.
