Re: Please help configure to activate Bluetooth networking for "Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01)" card

The instructions on the webpage:
https://github.com/winterheart/broadcom-bt-firmware/blob/master/README.md,

may please be perused

The firmware was already in the directory: /lib/firmware/brcm, but
still error messages were read on the terminal. Solved the issue.

There was a simple trick involved:
I had to make the file read-only for all. Then restart the computer.

Now:
# dmesg | grep -i bluetooth # Shows all Bluetooth driver info

Output:
[   29.102165] Bluetooth: Core ver 2.22
[   29.102210] Bluetooth: HCI device and connection manager initialized
[   29.102219] Bluetooth: HCI socket layer initialized

[  105.688426] Bluetooth: BNEP socket layer initialized

# dmesg | grep -i bluetooth | grep -i firmware # Shows Bluetooth firmware issues

Output: None

However, I am still receiving the same error messages for the other
commands as listed  on the post:
https://lists.debian.org/debian-user/2023/10/msg00871.html

I now would need your support to install specific packages and
reconfigure the settings so that I no longer receive the error
messages.

 may please be perused:

Some Bluetooth controller (for example, BCM4354 and BCM4356) are
integrated to WiFi chipset (this can be BCM43XX 802.11ac Wireless
Network Adapter or just simple generic Broadcom PCIE Wireless). These
devices requires two kinds of firmware - first for WiFi, and second
for Bluetooth. Without WiFi firmware Bluetooth will not initialize and
will not work properly. Firmware for WiFi already included to kernel,
but you may need to do additional work to place correct NVRAM.

Resolution needed for the above note.

Dear Mr. ullrich, I am so concerned by the Biblical God-like
Commandment of some of the senior members of this mailing list that I
have to ask you a second time: have you meticulously perused all my
posts relating to this problematic hardware?:
"Network controller: Broadcom Inc. and subsidiaries BCM43142

Also, I assume you have noted that I still continue to use the
oldstable system:  [Official Debian GNU/Linux Live 11.6.0 lxde
2022-12-17T11:46]/ bullseye

Sometimes I feel that some posters are actually planted here on the
Mailing List, and are heavily paid for their disruptions, by the
Proprietary Universe, to make Free and Open Source users like me lose
hope on the FSF ecosystem, feel frustrated and compel us to return to
the Proprietary Universe, turning away from the FSF/OpenSource system
and the Social Contract.

Then again, there are some who express their goodness and then vanish.
The latter, like Mr. Davidson, Mr. Curt, et al, are the ones who keep
my hope on humanity and the social contract intact. I still believe
that man could admire the best way forward: the positive non-zero sum
cooperative games, if he chose wisely.

You appear to be here since May 2011 in the debian-user ML. So you
appear to be a fairly senior member. Also, it appears that you have
been suggesting module-assistant since Jul 2011, thus experienced in
using module-assistant.

I have installed the m-a package, but not the rest, yet.

I hope that I will hear from you a second time. If I don't, then still ...

Try the following.





Building kernel modue:


1. Install the packages module-assistant, broadcom-sta, broadcom-dkms and 
broadcom-sta-

2. start module-assistant, command: m-a

3. In GUI enter  UPDATE

4. In GUI enter  PREPARE

6. In SELECT menu choose broadcom-sta and click ok

7. In GUI enter GET

You will need the firmware. The firmware is distribution independent, so you 
can get it from 
other distributions, like here from AUR:

https://aur.archlinux.org/packages/bcm43142a0-firmware[1]

Get it and put it manually into /lib/firmware

Dear Mr. Cater,

I took time to go through the list/description of Wireless network
cards in the package Description for which the driver   is suitable.
The list is as follows:
...
Supported chipsets:
 * BCM4306/3 (chip revision 3 only);
 * BCM4311 (NOT PCI Id 14e4:4313);
 * BCM4312;
 * BCM43131;
 * BCM4318;
 * BCM4321 (only partial support, not all versions tested);
 * BCM43217;
 * BCM4322 (only partial support for some versions, not all versions tested);
 * BCM43222 (not all versions tested);
 * BCM43224 (not all versions tested);
 * BCM43225;
 * BCM43227;
 * BCM43228;
 * BCM4331;
 * BCM47xx (detection not reliable, may not support all versions).

If observed carefully, the card which my laptop has is:
BCM43142 802.11b/g/n (rev 01)

None of the list-items has the said card mentioned. So I am doubtful
if this driver would even work.

Further, the webpage
https://wireless.wiki.kernel.org/en/users/drivers/b43#contact for the
"firmware-b43-installer"  may please be perused:

On the webpage the list with the following columns has the following
entries for the said chipset:
PCI-ID Supported? Chip ID Modes PHY version Alternative
14e4:4365 no BCM43142 b/g/n LCN40 (r3) wl

So it can be seen that the driver isn't suitable for my laptop's said card.

I again post my query to all Senior Members of the debian-user Mailing List:
If senior members have gone through this ML subject thread, your
experience is invited on the issue.

Once again the detailed dmesg output for the "bluetooth" section for
the said card is at the post:
https://lists.debian.org/debian-user/2023/10/msg00649.html.
Particularly:

# dmesg | grep -i -e "bluetooth"

[191884.268151] Bluetooth: hci0: BCM: chip id 70
[191884.269117] Bluetooth: hci0: BCM: features 0x06

[191886.295091] Bluetooth: hci0: unexpected event for opcode 0x1003

The wifi section works perfectly well.

Therefore, I would again return to my earlier post at:
https://lists.debian.org/debian-user/2023/10/msg00650.html

That is, the thread with the Subject:
Which Network Controller Card handling Wi-Fi, Bluetooth, etc.,
connectivities, is GNU/Linux Approved/certified, and would be (1)
compatible with my HP laptop's motherboard, and (2) could replace the
"Network controller: Broadcom Inc. and subsidiaries BCM43142
802.11b/g/n (rev 01)"

I desire a Debian approved list for perfectly compatible
Wireless-Bluetooth Cards. Like the PCI list, with the heading:
DeviceDatabase/PCI - Debian Wiki
at
https://wiki.debian.org/DeviceDatabase/PCI

Best wishes,
Rajib,
Etc.

Sure.

One note: the correct phrase would be "Inclusive Globalism", not
"Bharatiya Nationalism".

In the said post, as a reply to Mr. Dan Purgert  -'s

networking the extreme evil that ensues from a trans-generational

ample sunlight and rainfall ensured a bewilderingly rich biome with

Dear Rajib,

I can't help you because I don't have such a card / chipset.

Please ensure that your /etc/apt/sources.list includes entries 
for main contrib and non-free

See, for example, the version for Debian Bullseye (oldstable) in this
link: https://wiki.debian.org/SourcesList

Then do an apt update ; apt upgrade to bring yourself up to date.

Install the package firmware-b43-installer and follow the prompts.

I'm fairly sure that's all it takes. You may need to uninstall wl
and / or any other changes you've made.

As the author of the FAQ posting made here every month; 
Please do not post political / nationalistic / controversial
points here - Debian is worldwide and Bharat nationalism may be
misplaced as not everyone will appreciate what you are writing.

Hi Rajib,

I don't think you quite got the point I was making.

wl is one way round the problem. b43-fwcutter is the other, and more usual
way round this problematic Broadcom chipset.

If you go the b43 way, then you need to remove wl, I think.
The catch is that you need network access to download the Broadcom firmware
to make use of b43-fwcutter.

If you're unlucky, the wireless network card may actually be built into
the laptop chipset and not easily able to be changed. You may also find
that HP expect particular models and have deny-listed others.
