Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

I'm getting the following messages when I shut down my laptop:
Pretty sure bluetooth is not working, but I'm not sure because I did not configure bluetooth to work with Gnome yet, and I'm using netctl for my wifi, which works perfectly fine.

bluetooth hci0: firmware: rtl_bt/rtl8723b_fw.bin will not be loaded-part5...
Bletooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin
reboot: System halted

The only information I could find was very outdated and I have no idea how to fix it.

Have you read/followed the: arch bluetooth wiki page?

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

I have,

I could not manage to get bluetooth to work with either gnome-bluetooth or bluez-utils.

bluez-utils gives the following error:

Failed to set power on: org.bluez.Error.Failed

Hcitool scan also reports: "Device not available: No such device"

(this is a fresh install btw)

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

I fixed this error message downloading the file from here: Bluetooth driver for RTL8723AE and RTL8723AU and copied it like this:

sudo cp rtl8723b_config /usr/lib/firmware/rtl_bt/rtl8723b_config.bin

Direct link to file: https://github.com/lwfinger/rtl8723au_b … 23b_config

Now i dont have any errors:

For me the driver rtl8723be came out of the box listening on antena number 2 which was the weakest and generated wifi range / bad transmissions problem.

that same chip is used to manage bluetooth too so it is badly configured we get that error :

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

hum to be strict and precise ... those errors means dear user I tryed to load a certain file that doesnt exists for instance /lib/firmware/rtl_bt/rtl8723b_config.bin ... and effectively looking a that directory that file doesnt exists the only _config,bin like file in that directory is "rtl8722b_config.bin" ... so my guess is or  they miss typed the filename in the linux firmware package which would solve the issue by renaming or creating a symbolic link OR that particular file was forgotten and to solve this we should rebuild the kernel drivers.

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

ok so I downloaded too https://github.com/lwfinger/rtl8723au_b … 23b_config which the link was given by R3tr0G4m3r and store it in /lib/firmware/rtl/rtl_bt with the appropriate name rtl8723b_config.bin then rebooted then did a dmesg | grep -i Bluetooth which produced the following reply:

[    7.823773] Bluetooth: hci0: rom_version status=0 version=1
[    7.823807] Bluetooth: cfg_sz 44, total size 22540

as we can see the error on the loading file rtl_bt/rtl8723b_config.bin  is gone ! but still I have no bluetooth working gnome. Probably due to missing tools which gnome3 depends on to administrate bluetooth interface...

Still digging to get the bluetooth working

EDIT--
I read the Bluetooth config manual https://wiki.archlinux.org/index.php/Bl … ia_the_CLI
see that 2 packages where needed in bluetooth related affairs bluez and bluez-utils did a pacman -Ss bluez seen that bluez was installed but bluez-utils wasnt so I installed bluez-utils then did a systemctl enable bluetooth service systemctl start bluetooth.service and gnome then was happyly seeking for bluetooth devices which my android smartphone was able to detect my linux pc and that is really cool !!

For me problem solved. Hope my problem solving session will help you solve your problem too.

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

I've the same problem.

bluetoothctl
[bluetooth]power on
Failed to set power on: org.bluez.Error.Failed

rfkill list
1: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

Tried rtlwifi_new-dkms - my laptop wasn't even start after reboot (seems like somehow it loads no modules at all)
Tried direct file from #5 post - nothing changed
Didn't try  hciconfig because I think the problem is in the driver and when I try to install bluez-utils-compat:

yaourt -S bluez-utils-compat
...
ERROR: one or more PGP signatures could not be verified!

Since I think it's drivers - this dosn't worth a shot

I'll appreciate if someone helps me

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

breakneck,

Welcome to the Arch Linux Forums.  I have no idea if bluez-utils-compat will be of use, but I do think you need to brush up on the use of the AUR. 
https://wiki.archlinux.org/index.php/Ar … Repository
https://wiki.archlinux.org/index.php/Ma … e_checking
https://wiki.archlinux.org/index.php/Gn … public_key

I discourage the use of Yaourt.  If you want to use an AUR helper, you might pick one that is not quite so red.
Regardless, I strongly suggest you study how to hand fly makepkg so you know how it works prior to using an autopilot -- especially one prone to spectacular crashes.

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

I did

$ git clone https://github.com/lwfinger/rtlwifi_new.git
$ cd rtlwifi_new
$ git checkout rock.new_btcoex
$ make clean && make
$ sudo make install
$ sudo mkinitcpio -p linux

this time I booted properly, but had no effects. the same error that I've had before.
Tried to reload rtl8723be with ant_sel=1 and ant_sel=2 but all the same

Failed to set power on: org.bluez.Error.Failed

I don't know what to do, I tried all that I saw all over the internet. Please, someone, help T_T

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

breakneck you are missing /lib/firmware/rtl_bt/rtl8723_config.bin ...
copy it form the web site restart. Then if you try to connect a bt speaker to your notebook you will get a problem involving pulse audio that capture your bt speaker and adress it to the limbo ... so you have to force pulse audio to do nothing with that new "sound board" in order to get it working.
ln -s /dev/null ~gdm/.config/systemd/user/pulseaudio.socket

also googled this thing:

they say

cp rtl8723_config.bin rtl8723_config
cp rtl8723_fw.bin rtl8723_fw

Shadwolf, If you meant rtl8723b_config.bin (with b after the 8723) I already have this thing, it isn't helps.
I seached for it in github and google and I got nothing, please, tell me what did you mean

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

hum ... do a dmesg | grep rtl8723 if it says rtl8723_config.bin coudn't be loaded then you need to copy from the website I gave you that file to you arch linux /lib/firmware/rtl/

if not then your problem is somewhere else ...
Personally I had bluetooth working fine until they put the next kernel as files are missing and pulseaudio auto capture the interface when it detects it then each kernel update means spending a time figuring out why bt support is gone.

you have to start by the begining. Does the modules around bluetooth technology loads properly traduction in mondane words "Do I have in dmesg  bluetooth rtl8723 hci0 related errors ?
next do I use the rtl wifi new drivers other while I would en with a bt connected speaker that experience sound glitch ...
then do pulseaudio does properly  its job.

1) dmesg | grep -i Bluetooth and  you see there it there is a problem
2) bluetoothctl do you have it ? can you trust pair connect to the bt speaker ?
3) pulseaudio -start what does it say ?

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

So what the kernel bluetooth driver is loading ok...

so now you need to use bluetoothctl to "connect" your bluetooth headset.
/etc/pulse/default.pa should have those lines

.ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy
.endif


.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif


in bluetoothctl you need to do those commands

power on
scan on
then you will have to put your device in descovery mode and it should appear in the device list
then trust <device_ID>  Device id is something like AA:BB:00:11:22 etc.. it should be next to your device name

#bluetoothctl
[NEW] Controller CC:B0:DA:CD:8E:58 mylinux [default]
[NEW] Device 40:EF:4C:E0:61:8F PBT-750BK <-- my bluetooth speaker
[NEW] Device 40:88:05:75:02:C3 XT1097

then you will need to do a connect <device_ID> and you will have its all ok or it fails with an error message.

I do appreceate that you're trying yo help, but as I've already posted - I CAN'T power on my bluetooth. That's the whole point.

first thing I said
tried hciconfig
rebuilded drivers and tried again
you asked me do it again and I did

There is what I have:

$ bluetoothctl
[NEW] Controller B8:86:87:99:FA:77 arch [default]
[bluetooth]# power on
Failed to set power on: org.bluez.Error.Failed

[bluetooth]# scan on
Failed to start discovery: org.bluez.Error.NotReady

Re: Bluetooth: hci0: Failed to load rtl_bt/rtl8723b_fw.bin

hello,

$ bluetoothctl
[NEW] Controller B8:86:87:99:FA:77 arch [default]
[bluetooth]# power on
Failed to set power on: org.bluez.Error.Failed

[bluetooth]# scan on
Failed to start discovery: org.bluez.Error.NotReady

I had the exact same problem and solved it, to sum up it is caused by laptop-mode which power off the bluetooth

see : https://bbs.archlinux.org/viewtopic.php?id=221635
and : https://wiki.archlinux.org/index.php/La … _up_events

Regards !

Thanks a lot! It helped. Now I'm trying to know how to use my bluetooth headphones with laptop, can't get sound in it, but it is an another story, this topic should be closed.
Thanks everyone, thanks fedcod.
