Re: [Bluez-devel] FW: Need some help - linux bluetooth driver

the Linux 2.4 part of BlueZ is actually no longer officially supported
and so you can't expect any real help here.

However the 2.4.22 might be recent enough to get you going and it
contains the Bluetooth core.

Since this looks like a vendor specific kernel that you have paid for,
it might be better to complain with that company and make them include
the Bluetooth sources again. I am serious here.

So in theory it is possible to compile the kernel modules outside the
kernel source tree, but I don't remember the exact steps for a 2.4
system and quite frankly, I am not going to look that up.

The best way is to go for a 2.6.22 kernel or later. It might look
complicated in the beginning, but it is always worth the extra work. It
will give you a recent Bluetooth stack that is known to be qualifiable
and is up-to-date.

Marcel
