Samsung SM-T805 with Android 5.0.2 disconnectar

Hi,
Why does the app and Flic button loose their connection some times? Nothing happens when I push. It shows Out of range even if it is close and worked a day ago. Bluetooth is on, and if I try to add a flic by using the same button it says it is connected so the button transmits.
