Ubuntu

Bluetooth not detecting other devices, other devices not detecting PC

Asked by Fahad

Hey there!

I've recently installed Ubuntu on my Acer Aspire E14. The computer has a Qualcomm Atheros QCA9565 network card built in. The bluetooth adapter is integrated with this network card.

Ubuntu (14.04) can detect the bluetooth adapter, but whenever I select "add new device" or "scan" on bluetooth manager, it just keeps scanning, and no devices are detected (even though there are visible bluetooth devices nearby). When I turn on visibility on the computer, my phone can not detect it. I've tried all the solutions (upgrading, updating) on the internet, but none of them have worked.

I'd be glad if somebody could help me fix this, or tell me what's wrong. I suspect that Ubuntu doesn't support the device yet; is that a possibility?

If you have opened a bug then you don't need a question as well.

What bluetooth device is it, in terminal enter
lsusb
and post the results

Revision history for this message
Jeremy (wa113y3s) said : 		#3

Now to see if your kernel version supports it
modinfo ath3k | grep -i e078
If the result looks like
alias: usb:v0489pE078d*dc*dsc*dp*ic*isc*ip*in*

You may have another issue, if there is no result, then show the result of
uname -a

"modinfo ath3k | grep -i e078"
Returns no results.

Download this and extract it to your home folder https://www.dropbox.com/s/14wqp7t8u2026ds/test1.zip?dl=0
then in terminal enter the following, one line at a time

sudo apt-get install build-essential linux-firmware
cd test1
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers

make al
l
sudo modprobe -r ath3k

sudo modprobe -r btusb

sudo mv /lib/modules/$(uname-r)/kernel/drivers/bluetooth/ath3k.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/ath3k.ko.bak

sudo mv /lib/modules/$(uname -r0/kernel/drivers/bluetooth/btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko.bak

sudo cp ath3k.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/

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

If there are issues after shutdown and booting, then

echo "blacklist ath3k" | sudo tee /etc/modprobe.d/ath3k.conf

sudo gedit /etc/rc.local

Add the following lines above 'exit 0' as exit 0 must be the last line in the file

sleep 20
modprobe ath3k

Save, exit program, and try a restart again

The line that is below this one in the above post: cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
Should be

make all

not make al

Nope, Issue persists; I just get a different "Blueman apple 1.23."
That is, the PC still can't find other nearby visible bluetooth devices, and other bluetooth devices can't find the PC (yes, I've made the PC discoverable).

Have you rebooted since or
sudo modprobe btusb
sudo modprobe ath3k

Fahad (fahadmonster) said : 		#9

Yes, I've followed the instructions precisely.
Thanks for trying to help! Really appreciate it.

Any errors listed from
dmesg | grep firmware

Jeremy (wa113y3s) said : 		#11

One other thing I forgot about
sudo load-module module-bluetooth-discover

Revision history for this message
Fahad (fahadmonster) said : 		#12

"dmesg | grep firmware" returns no error;
"sudo load-module module-bluetooth-discover" returns "sudo: load-module: command not found"

I hate posting from my phone
sudo pactl load-module module-bluetooth-discover

Fahad (fahadmonster) said : 		#14

It just returns "24," problems still there.

Jeremy (wa113y3s) said : 		#15

lsmod | grep bluetooth
And redo the modinfo command from post #4
Reboot, it should be working

If you can boot to kernel 3.13.0-39 feel free to use the drivers from my post http://forums.linuxmint.com/viewtopic.php?f=53&t=183644#p951951

Copy those two files from the folder into /lib/modules/3.13.0-43-generic/kernel/drivers/bluetooth/
then
sudo modprobe -r btusb
sudo modprobe -r ath3k
sudo modprobe btusb
sudo modprobe ath3k

I just compiled those from source patched to include your device- you were correct as it is not supported yet in the Ubuntu 14.04 or 14.10 kernels

Thanks! Fixed my problem!
You said that as a comment, could you please post it as an answer, so that I can select "This Solved My Problem?"

Hopefully the device is supported in the next kernel because these modules will only work with 3.13.0-43
