Workaround

mkdir /mnt/data/firmware
cp -afv /lib/firmware/* /mnt/data/firmware
mount -o bind /mnt/data/firmware /lib/firmware

Install the bcrm dir from https://github.com/winterheart/broadcom-bt-firmware into /mnt/data/firmware/bcrm,

unplug and replug adapter

Must be done on every boot

This PR fixes the discovery home-assistant/core#81926

CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y is only enabled on the Odroid n2+ platform so this issue is most relevant there.

This slows down firmware loading which causes Bluetooth initialization to delay unecessarily.

#2222 (comment)

I tried the workaround to make my broadcom adapter work again with no success. The mount does not work:

[core-ssh ~]$ mount -o bind /mnt/data/firmware /lib/firmware

mount: mounting /mnt/data/firmware on /lib/firmware failed: Permission denied

I have a SSD attached to ODROID-N2+ and moved all data to SSD using Home Assistant http://homeassistant.local:8123/config/storage

When will there be a permanent solution to this problem?

bdraco · 2023-01-20T06:48:01Z

When will there be a permanent solution to this problem?

I would pick up one of the CSR adapters from the High performance list at https://www.home-assistant.io/integrations/bluetooth/ since they don't need any patch files.

I'm using the Feasycom FSC-BP119 (CSR8510A10) US $19.99 | 100m Long range Bluetooth USB Dongle Wireless Bluetooth 4.0 CSR Adapter for Windows 10, 8, 7 XP vista

nagi121 · 2023-01-20T06:59:36Z

If I am right, the BCM firmware patch files fix a security issue.
Buying other hardware is only an intermediate solution, because in the future the new hardware may also need firmware updates to work.

I think, a solution is needed to provide the Homeassistant OS with firmware patch files from other sources. I would like to have a folder, where I can place the downloaded firmware patch files and they will be picked up at startup. Maybe a script like the workaround mentioned above.

dbuezas · 2023-04-15T10:22:26Z

@bdraco I can't get the workaround to work. I tried:

copying the file directly to /lib/firmeware/bcrm (I assume that was a typo in your post but tried anyway)
copying the file directly to /lib/firmeware/brcm
copying the file directly to /lib/firmeware/
rebooting and retrying
removing and reinserting the dongle after each step
using mnt/data and your exact bash commands (I had to mkdir /mnt/data too)
adding the single file dmesg | grep -i bluetooth asks for
adding all files from the drivers repository
renaming the file to the second name dmesg suggests

And unfortunately nothing seems to work :(
I have a Home Assistant Blue running 2023.4.1 and

 ➜  dmesg | grep -i bluetooth

always gives back

[ 2341.885901] Bluetooth: hci2: BCM20702A
[ 2341.885916] Bluetooth: hci2: BCM20702A1 (001.002.014) build 0000

[ 2341.894405] Bluetooth: hci2: BCM: 'brcm/BCM-0a5c-21e8.hcd'

Anything else I can try? I have other two dongles working:

Feasycom FSC-BP119 (CSR8510A10) 📶
ZEXMTE BT-505 (RTL8761BU) 📶
but I'd really to get my LM Technologies LM1010 (BCM20702A0) 📶 working again

Any tip highly appreciated :)

You can use #2225 now if you are running the 10.x RCs

dbuezas · 2023-04-15T20:08:43Z

Thank you for the pointer, this looks promising but I still didn't succeed.
Am I doing something wrong?

I'm now on 10.x RC

➜  ~ ha os info

data_disk: G1J39E-0x116d3956
update_available: false

I created the folder in the right place and copied the driver it is asking for there

➜  ~ ls -la /mnt/data/supervisor/firmware/brcm/BCM20702A1-0a5c-21e8.hcd

But it still doesn't find it

➜  ~ dmesg | grep -i bluetooth

It looks right to me. Looks like #2225 might need some more work

emontnemery · 2023-05-09T09:30:01Z

This works for me on a dev build where the feature was just introduced.

@dbuezas Based on what you've pasted above it looks like you've created a /mnt/data/supervisor/firmware from within the ssh docker container, which won't work.

To access the host via ssh: https://developers.home-assistant.io/docs/operating-system/debugging/#ssh-access-to-the-host

Output from host ssh:

I can confirm this works and I had missed the fact that this needed to be done from the host, not via "normal" ssh with the AddOn.

SUCCESS!

I ran this script from the host's keyboard

#!/bin/bash
mkdir -p /mnt/data/supervisor/firmware/brcm
cd /mnt/data/supervisor/firmware/brcm
curl -O https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM20702A1-0a5c-21e8.hcd

Thank you both @bdraco and @emontnemery!
I hope there will be a more straightforward way at some point, but thanks for making this possible at all :)

github-actions · 2023-08-07T18:02:55Z

There hasn't been any activity on this issue recently. To keep our backlog manageable we have to clean old issues, as many of them have already been resolved with the latest updates.
Please make sure to update to the latest Home Assistant OS version and check if that solves the issue. Let us know if that works for you by adding a comment 👍
This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

I get the following error in HA.
firmware patch not found, tried brcm/BCM20702A1-0a5c-21f1.hcd brcm/BCM-05ac-21f1.hcd

Is there a way I can solve this myself?

I think I solved it by using these lines from the terminal add on:
#!/bin/bash
mkdir -p /mnt/data/supervisor/firmware/brcm
cd /mnt/data/supervisor/firmware/brcm
curl -O https://github.com/winterheart/broadcom-bt-firmware/raw/master/brcm/BCM20702A1-0a5c-21f1.hcd

host reboot

When HAOS rebooted the error was not there.
How do I know if the bluetooth device is there?
