Broadcom 43340 BT support

["Jürgen Bausa" <Juergen.Bausa@online.de>]

I have a laptop (asus x205ta / intel-baytrail) with the broadcom 43340 
chipset. However, while wireless is working now, bluetooth is not. I am 
running debian jessie 32 bit with kernel 4.0rc4:

I have no idea where to start in order to enable BT. is there a driver yet? Do 
I need a firmware file? Where to get it, where to put it?

Any hints welcome.
