Lost connection to bluetooth devices, cannot pair again.

Dear Arch Users,

I am currently unable to pair any bluetooth devices with my machine. Until yesterday, I had successfully paired both a Logitech K811 keyboard and my Bose QC35 headphones. After a reboot (I was working on pulseaudio), the connection failed and I have not been successful in restoring it.

Devices to pair: Logitech K811 keyboard, Bose QC35 headphones

I have read and followed the instruction in the wiki ( https://wiki.archlinux.org/index.php/Bluetooth , https://wiki.archlinux.org/index.php/Bl … _keyboard)

The following packages are installed: bluez 5.44-1 , bluez-utils-compat[AUR] (bluez-utils does not work either), blueberry

Here is what I tried using the commandline:

bluetoothctl
[NEW] Controller [MAC ADDRESS] FZWS [default]
[NEW] Device [MAC ADDRESS KEYBOARD]  [MAC ADDRESS KEYBOARD] 
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent KeyboardOnly
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on
Discovery started
[CHG] Controller 54:8C: A0:54:41:54 Discovering: yes
[CHG] Device [MAC ADDRESS KEYBOARD]  LegacyPairing: yes
[CHG] Device [MAC ADDRESS KEYBOARD]  RSSI: -38
[bluetooth]# pair [MAC ADDRESS KEYBOARD] 
Attempting to pair with [MAC ADDRESS KEYBOARD] 
Failed to pair: org.bluez.Error.AuthenticationTimeout
[bluetooth]#

As I said, this worked before and I was able to enter a PIN on the keyboard.

Attempted problem resolutions:
- Downgraded all arch packages to 1 March using Archive --> Not resolved
- Deleted /var/lib/bluetooth
- Tried to pair many times, rebooted
- Tried https://wiki.archlinux.org/index.php/Bl … s_not_pair with no luck
- Tried blueberry GUI, no luck

The arch linux installation is fully updated as of tonight.
Any help is appreciated and please do let me know if you need additional information.

Best,
F

Re: Lost connection to bluetooth devices, cannot pair again.

Hi Docbroke,

Thanks for the suggestion, but it did not resolve the issue:

bluetoothctl
[NEW] Controller [MAC ADDRESS] FZWS [default]
[NEW] Device [MAC ADDRESS] [MAC ADDRESS]
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent KeyboardOnly 
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on
Discovery started
[CHG] Controller [MAC ADDRESS] Discovering: yes
[CHG] Device [MAC ADDRESS] LegacyPairing: yes
[CHG] Device [MAC ADDRESS] RSSI: -37
[bluetooth]# trust [MAC ADDRESS]
[CHG] Device [MAC ADDRESS] Trusted: yes
Changing [MAC ADDRESS] trust succeeded
[bluetooth]# pair [MAC ADDRESS]
Attempting to pair with[ MAC ADDRESS]
Failed to pair: org.bluez.Error.AuthenticationTimeout

Any other ideas?

Cheers,
F

Re: Lost connection to bluetooth devices, cannot pair again.

Have you paired your devices with something else (another computer?)? Do you have some key on your device that needs to be pressed when pairing first time?, this may be useful if you have paired your device with some other computer in-between.
Do you get same error with "connect"?

Re: Lost connection to bluetooth devices, cannot pair again.

Hi,

Yes, I paired the keyboard successfully to my iPhone. I need to press a button on the back to get it into pairing mode, which I do everytime I use bluetoothctl.

I do get the same error with "connect":

bluetoothctl

Re: Lost connection to bluetooth devices, cannot pair again.

Are you keeping bluetooth in your iphone off, while trying to pair keyboard with your computer??
You shall not need to press that button everytime, if it is paired once, you should get away with "power on" and "connect" or I think only "power on" not even "connect".

Re: Lost connection to bluetooth devices, cannot pair again.

remove the device from bluetoothctl, followed by scan, trust, pair and connect

Re: Lost connection to bluetooth devices, cannot pair again.

I did this, but no luck unfortunately. I could also successfully pair my keyboard on my MacbookPro under MacOS. So this is not an issue with me being unable to get the keyboard into pairing mode.
Are there any configuration files that I should reset and/or setting I could change?

Cheers,
F

Re: Lost connection to bluetooth devices, cannot pair again.

What is the wireless device 

lspci -nnk | grep -iA2 net

I suspect it is Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32)

Lets see some more info about the bluetooth 

usb-devices | awk '/1825/' RS=

The Atheros bluetooth chipsets have needed firmware to work for quite some time and I see no sign of the device ID in bluetooth source code, are you dual boot with Windows?

Hi jeremy31,

You were spot on! It is this exact model:

And yes, I dual boot with Windows (unfortunately..).

It also appears a firmware version is missing?

That is normal for the wireless card you have.  The pre-cal-pci and cal-pci seem to be files that would be needed to run the card in a router in AP mode and only one firmware-*.bin file is needed and you seem to have a 4 version

For a test, do a shutdown and then boot into Windows then a reboot into Arch and I think bluetooth will work in Arch from the firmware that Windows loads

Re: Lost connection to bluetooth devices, cannot pair again.

I rebooted according to your instructions and still no luck. FYI I also tried pairing in Windows and that did not work either?

P.S. I am connected via WiFi, which works well.

Re: Lost connection to bluetooth devices, cannot pair again.

See https://wiki.archlinux.org/index.php/Co … nel_module and install base-devel and linux-headers and download the kernel source for your kernel.  Then go into the /drivers/bluetooth directory and use a text editor to open btusb.c
Some where around line 260 you should find something similar to this

	/* QCA ROME chipset */
	{ USB_DEVICE(0x0cf3, 0xe007), .driver_info = BTUSB_QCA_ROME },
	{ USB_DEVICE(0x0cf3, 0xe009), .driver_info = BTUSB_QCA_ROME },
	{ USB_DEVICE(0x0cf3, 0xe300), .driver_info = BTUSB_QCA_ROME },
	{ USB_DEVICE(0x0cf3, 0xe360), .driver_info = BTUSB_QCA_ROME },
	{ USB_DEVICE(0x0489, 0xe092), .driver_info = BTUSB_QCA_ROME },
	{ USB_DEVICE(0x04ca, 0x3011), .driver_info = BTUSB_QCA_ROME },

and in that code add 

	{ USB_DEVICE(0x0b05, 0x1825), .driver_info = BTUSB_QCA_ROME },

Make sure the indent matches the rest and save the file
Then you can follow the instructions at the link for source configuration and module compilation.  I usually make modules with 

make -C /lib/modules/$(uname -r)/build M=$(pwd) modules

This will make all modules in the directory but we just need to copy the one after compressing it so

gzip btusb.ko
sudo cp btusb.ko.gz /lib/modules/$(uname -r)/kernel/drivers/bluetooth/

Reboot and check 

dmesg | egrep -i 'blue|firm'

Re: Lost connection to bluetooth devices, cannot pair again.

Awesome, will do. I also think that you are active in the Ubuntu forums (at least someone using the same name) and it appears there is a similar bug report reported for Ubuntu: https://bugs.launchpad.net/ubuntu/+sour … ug/1665589

Back in a second.

Re: Lost connection to bluetooth devices, cannot pair again.

It is similar as that device isn't in the source code yet but he messed his wireless firmware up as those -11 errors are usually board.bin related.  I hope it works

I am a moderator on the Ubuntu and Mint forums and I mess around with an Arch ISO I have on USB, nothing but terminal isn't so bad sometimes

and when trying to pair still no luck sad I am really confused why this stopped working..

Re: Lost connection to bluetooth devices, cannot pair again.

Probably should check 

dmesg | egrep 'btusb|taint'

To make sure the right module is being loaded or we could redo the module and change 

#define VERSION "0.8"

to 

#define VERSION "1.1"

before compiling then a simple 

modinfo btusb | grep -i version

would tell if the modified one was loaded.  I wonder if an error would pop in dmesg if /lib/firmware/ar3k was renamed to /lib/firmware/ath3k. Then reboot and check 

dmesg | egrep -i 'blue|firm'

If nothing else the question should be asked after registering at http://www.bluez.org/development/lists/ so this gets fixed upstream.  Send plain text emails and include results for 

usb-devices | awk '/1825/' RS=

I guess it it possible that the btusb.c at about line 151 could be an issue and could be deleted in your case

	/* ASUSTek Computer - Broadcom based */
	{ USB_VENDOR_AND_INTERFACE_INFO(0x0b05, 0xff, 0x01, 0x01),
	  .driver_info = BTUSB_BCM_PATCHRAM },

before compiling, zipping and copying the module

Re: Lost connection to bluetooth devices, cannot pair again.

Thank you, Jeremy. I have updated the btusb module accordingly, but am still experiencing the same issue. I will report upstream and see where I get.
Thanks for your excellent help!
