'Connection Failed'. I paired my laptop to my phone via Bluetooth  it paired successfully. I open up Libreoffice Impress Remote and chhose my laptop. After that  nothing happens. It shows an error. 'Make sure you've enabled remote control Impress>Tools>Options>General enable remote control'. I've enabled the option and restart libreoffice. It still doesn't work like the video you've shown. I am running Xperia Z2 5.1.1  my laptop is Windows 8.1. Libreoffice Impress version 4.4.5.2 on Windows8.1. I'll edit this comment to inform if everything worked out.
