Using Vizio VUR10 as a bluetooth keyboard and mouse

I am not rooted and I have a Galaxy Note 2 from ATT model I317. I was able to pair my Vizio tv remote to my phone using bluetooth, it is a VUR10. It works great for a while, but if I am not constantly using it the phone seems to forget that it is there or only part of the buttons work. I thought that I read in some other forums that the Galaxy products do have a bad habit of loosing the bluetooth connection with some devices. Is there a better way to utilize this remote as a keyboard without being rooted? Any apps that would help make it more functional or fix the bluetooth problem. I really want to use this remote while I have my phone hooked up through the smart dock. At this point I don't have a usb powered hub to hook up to the smart dock to use a wireless keyboard/mouse combo.
