Impress remote not working

I have a Samsung SM-P601 Tablet with Android 5.1 and Win 8.1 Laptop with Libreoffice 5.0.5

I have tried to connect via Bluetooth or WiFi and all the time I get Connection failed message. Are there any ideas what to do? I’ve tried restarting everything, deleting and pairing Bluetooth devices. Bluetooth works, Wifi works (I can connect Tablet and laptop using another apps).
