Latitude 3350 Bluetooth Stops Functioning

Every couple of months I have an issue with my Latitude 3550 laptop where the Bluetooth stops functioning out of the blue (pun kind of intended).  The error I get is: 

Disabling / enabling or uninstalling /reinstalling the Bluetooth under Device Manager does not fix it.  Neither does reinstalling the driver.  So far the only thing I have found that resolves it is to update (or reapply) the latest BIOS firmware.  Then it works again for a couple of months.

Any reason that this would keep happening, or at least is there a lesser means to fix this issue?  Thanks for any input you may have!
