For kernel 3.19 that you have I made a fix. Install DKMS by

sudo apt-get install dkms

and install these debs:

https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi/+files
/rtlwifi-new-dkms_0.9~wily_all.deb

https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi/+files
/rtl8723au-bt-dkms_0.7.1_all.deb

and the BT shuold start working.

For kernels 4.2+ it is supposed to be supported out of the box. But this
is not the case as far as I see.

Title:
  Bluetooth disabled

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Bluetooth does not work. In settings it is set to ON but the
  visibility option is greyed out. Since install of elementary OS freya
  from Windows 10, I have not been able to use Bluetooth. My PC is HP
  15-r201ne, it has a Realtek card - can't remember the command for
  getting the exact model.

  Maybe this output will help diagnosing the problem,

  lsusb; dmesg | grep -i bluetooth; dmesg | grep -i firmware; rfkill
  list all; lsmod | grep bluetooth; hciconfig -a; uname -a
