BCM43142 on Acer E5

[TT]

I'm using an Acer E5-551 (AMD FX-7500 Radeon R7) computer, equipped with 
Broadcom BCM43142 Chip:
- PCI-ID = 14e4:4365
- Chip ID = BCM43142  (b/g/n)

WLAN is working more or less (only if the laptop has a short distance to 
the WLAN access point). The Bluetooth interface does not work at all. In 
https://wireless.wiki.kernel.org/en/users/Drivers/b43 the BCM43142 
device is listed as "not supported".

Since 2 years I'm hoping, kernel version by kernel version, to get 
driver support.

Is there a chance to get a solution?
Can you provide necessary documents, so I can develop a driver for the 
Ubuntu users and myself?



Yours sincerely
TT
