Re: Using bluez-utils from another application

Hi Johannes,

your version is ancient. I have the release date as January 2006 and
this means it is over two years old. That is a full lifetime in the
Linux world.

I am simply not buying the D-Bus cross-compilation issue. Sorry, but it
is not that hard.

> By the way Im using a 2.2.21 Kernel, but the bluetooth related stuff is patched to 2.2.26.

We never had a 2.2.21 kernel with Bluetooth support.

You are going to duplicate all the work that has been done for now
reason. Spending the time to cross-compile D-Bus would be better
invested.

Again, cross-compile D-Bus and use our D-Bus based API. It is more
elegant than any low-level stuff will ever be.

Yes. You always have to open a HCI raw socket to do raw packet
manipulation.
