You Bluetooth is:
 Bus 001 Device 003: ID 0a5c:21d7 Broadcom Corp. BCM43142 Bluetooth 4.0

Which needs a special firmware from Boradcom to make it work, see

Title:
  dell inspiron 3521 laptop bluetooth does not connect to any device

Status in gnome-bluetooth package in Ubuntu:
  New

Bug description:
  With my Dell inspirion laptop i noticed some strange behaviour:

  When i turn on my laptop and start ubuntu 14.04 (also experienced this with 12.04 and previous versions)
  My Bluetooth never could connect to any device. 

  But when i first turn on my laptop in windows 7 (i have a dualboot)
  then close Windows 7 and restart (not shut off) but restart in Ubuntu 12.04 or 14.04 my bluetooth adapter works fine..
  When i then again shut off and turn back on my laptop the problem persists...
