BlueTooth Broadcom hardware - no connection

**nicolasdiogo** · October 26th, 2015

hello guys,

I have a nice Lenovo X1 laptop that works perfectly except for the BlueTooth.
My headset works fine on Android (receiving & sending sound) but it will not work at all with my laptiop.

Every time I tried adding this headset it says that i had been added but it failed to pair.

while researching for a solution I have collected some info:

Code:

$ dmesg | egrep -i 'blue|firm'

I have come across this discussion:
http://askubuntu.com/questions/54755...-with-bcm43142

and I have also found some windows binaries as discussed on the above:
http://drivers.softpedia.com/dyn-sea...h_term=bcm2070

While searching the DEB packages, I could not find anything that would appear to support this Broadcom chipset.

Would it be possible to have some guidance on the steps to have this bluetooth connection?

Thanks,

[bumping]

perhaps Friday is a good day to have this topic revised?!

however, it looks like we have to extract the necessary files from the Windows Binaries:

These days ... companies should provide Linux support as default
Or, I am too positive!

Thanks

Found you the file.

Code:

wget https://www.dropbox.com/s/p6h7ho21fct2pzb/fw-0a5c_21e6.hcd
sudo cp fw-0a5c_21e6.hcd /lib/firmware/brcm/BCM20702A1-0a5c-21e6.hcd

Shut down and cold boot the computer

Thanks

I believe the file that you linked is the correct one.

Now I find that Ubuntu does not send any sound the headphones.

Perhaps I try fixing this another day.
