Hello,

would someone please explain to me why does bluez support D-Bus? What are the advantages by using dbus instead of simply linking and using the bluez C library?

Thanks

Hi Aleksander,

a C library has no concept of privilege separation. Every client would have to be setuid-root since there are tasks that require root privileges. Without a suid-root client, we would need a message passing interface within hcid for these task. And guess what D-Bus is.

Also D-Bus provides bindings for almost every language and the license for a Bluetooth client using D-Bus is no longer bound to the GPL.

Besides that are multiple technical reasons why D-Bus is the right choice for a Bluetooth API.
