That is what I expected, so

And your bluetooth should work but there is an issue that might cause it not to function at times after rebooting that is fixed in kernel 3.16.0-32 and 3.19.1 but I do know a workaround for your current kernel

thanks for the reply I will try that I am using the kernel that came with cinnamon 17.1 Edit: Command

Code: Select all

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

errors and says no such files or directory

[JeremyB]

I wonder why that error happened

Code: Select all

ls ~/bluetooth-3.13 | grep .ko

[coolmark1995]

I wonder why that error happened

Code: Select all

ls ~/bluetooth-3.13 | grep .ko

I entered the above code but it required me to get rid of the -3.13 and it outputed

Code: Select all

btusb.ko

Edit: doing all the details you have provided seems to have disabled my bluetooth any suggestions on how to fix it?

[JeremyB]

Is there a file named ath3k in the bluetooth folder? It is needed to upload firmware so the bluetooth can work

[JeremyB]

I figured out what happened. In a new terminal window

Code: Select all

cd bluetooth

Code: Select all

rm *.ko  && rm *.o

Code: Select all

rm Makefile

Code: Select all

cp oldmakefile Makefile[code]
[code]make -C /lib/modules/$(uname -r)/build M=$PWD modules

Code: Select all

sudo modprobe -r btusb

Code: Select all

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

Code: Select all

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

Code: Select all

sudo apt-get install linux-firmware

No problem, I had a custom Makefile in there that I forgot about and after renaming the original it was able to work
