[Bluez-users] dbus connection failed

[Vincent Yau]

Hi:

I am trying to use the DBUS API in my pin exchange script.  I got a DBUS 
connection error when I execute this line:

   DBusConnection *conn = dbus_bus_get(DBUS_BUS_SYSTEM, &err);

When I print out err.message, I got a bunch of non-printable character so I 
could not quite figure out what the error is.

However, I took the same DBUS line and put in a stand-alone program and it 
works fine.

In my /etc/dbus-1/system.d, there is bluetooh.conf which is identifcal to 
the config that ships with Bluez.  I even explicitly include bluetooth.conf 
in my /etc/dbus-1/system.conf file.

I tried Bluez-Utils 3.7 and 3.9 and with the same results.

Is there any special trick to connect to DBUS system bus from within Bluez?

thanks

take a look at the example code in bluez-utils. I think that
passkey-agent.c is the easiest one.
