bluez-utils on old kernel

Hello everybody,

I'm trying to add bluetooth support to my arm based NAS which runs on a 2.6.10 Kernel.

I compiled the bluez-libs and utils (3.11) but hcitool dev won't show any devices and when I exec hciconfig I get

icybox / # /system/overlay/apps/bluez-utils/sbin/hciconfig
hci0: Type: USB
BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0 DOWN INIT RUNNING
RX bytes:0 acl:0 sco:0 events:0 errors:0
TX bytes:0 acl:0 sco:0 commands:0 errors:0

so I think the device is somehow active but I can't nether reset nor do anything usefull with the bw-dongel.

I then tried to apply the latest kernelpatch to the 2.6.10 kernel which gives lots of errors

bash-2.05b# patch -p1 < patches/patch-2.6.21-mh1 patching file drivers/bluetooth/hci_ldisc.c

My question is: is it possoble to upgrade the kernel (bluetooth) step by step because a jump from 2.6.10 to 2.6.21 is quite big i guess. Or do i make something else wrong?

Thanks for your help.

bye
Philipp

Hi Phillip,

I have no idea what went wrong, but it looks like an init issue and is maybe actually a kernel bug that we already fixed.

This will never work. The patch has 2.6.21 in its name and that means it only applied to 2.6.21 source code.

Upgrading the kernel to 2.6.21 is easier. It might be possible to backport all the Bluetooth patches, but that takes time and I would personally charge a lot for doing that.

Regards

Marcel

I did the same. I have utils 3.11 on 2.6.10. it is not vanilla 2.6.10 though - it is from embedded distribution, but things seems to work.

just my 2 cents.
