Troublesome Broadcom 43142 wireless & bluetooth working

After spending lots of time I got the wireless internet and the bluetooth connection of my Broadcom 43142 built-in chipset finally working.
I wrote a step-by-step file, primarily for myself to be able to repeat it again in the future, but perhaps this might be of some interest for other users too.
I can't explain every step though, because I have not enough knowledge to do that, but noted down most of the url's with the information I used.

Should I post this step-by-step file somewhere and if so, where?

What type of system are you using? I have a dell laptop with the same chip set and was able to use the following to get the adapter working

sudo dnf install kernel-devel akmod-wl
sudo akmods --force
sudo modprobe wl

Re: Troublesome Broadcom 43142 wireless & bluetooth working

I have a Dell Inspiron 11 3000 with the same wifi / bluetooth chip. I made the wifi work with kernel-devel akmod-wl and broadcom-wl, but bluetooth still wasn't working. What I had to do in order to make the bluetooth work was this:

I copied the driver folder from my Windows partition. You can download the folder here:
https://www.dropbox.com/sh/5baoyxhkv...5DW7msuLa?dl=1

The folder has a bunch of .hex files. In order to figure out which one I needed, first I found out my device ID using the lsusb command:

Code:
$ lsusb
Bus 001 Device 003: ID 0a5c:216a Broadcom Corp. 
Bus 001 Device 002: ID 8087:8000 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 004: ID 04f3:036e Elan Microelectronics Corp. 
Bus 002 Device 003: ID 1bcf:28aa Sunplus Innovation Technology Inc. 
Bus 002 Device 002: ID 0483:91d1 STMicroelectronics Sensor Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
So, my device ID is 0a5c:216a. I needed the last four characters 216a, in order to identify the correct .hex file for my device.

In the driver folder I opened the file bcbtums-win8x64-brcm.inf with a text editor, and within that file I searched for the last four characters of my device ID: 216A (it has to be all upper case).

This is the part that I needed:

Code:
;;;;;;;;;;;;;RAMUSB216A;;;;;;;;;;;;;;;;;

[RAMUSB216A.CopyList]
bcbtums.sys
btwampfl.sys
BCM43142A0_001.001.011.0311.0336.hex
So the correct .hex file for my device is BCM43142A0_001.001.011.0311.0336.hex

I created a new directory named BCM in my home folder and copied the .hex file to it. Then I converted the .hex file to a .hcd file with the hex2hcd command (it's part of the bluez package):

Code:
$ hex2hcd ~/BCM/BCM43142A0_001.001.011.0311.0336.hex
And finally I copied the resulting .hcd file to the /lib/firmware/brcm/ directory, under the name BCM.hcd (if you don't rename it, it won't work):

Code:
$ sudo mv ~/BCM/BCM43142A0_001.001.011.0311.0336.hcd /lib/firmware/brcm/BCM.hcd
I used my device ID and that specific .hex file as an example. You have to find the ID of your own device and use the corresponding .hex file.
