Hi:  I am trying to use the Bluez-DBUS API in my Bluetooth device 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/configuration to connect to DBUS system bus from within Bluez Bluetooth stack? thanks   --v <pre> </pre>
