[Bluez-users] dbus agent problem

[Jelle de Jong <jelledejong@powercraft.nl>]

Hello everybody

I am still trying to get my bluetooth headset working again, the problem
is that my dbus agent does not work anymore!

I would like to have a checklist what is needed to have an functional agent.

As you can see there is no key send to the device anymore and the agent
is not working, so i would really appreciate a checklist what is needed
to have a functional agent.

Thanks in advance,

Kind regards,

Jelle
