I have changed the code of bluez/src/manger.c,

the siample question is:
1) for dbus_connection_send_with_reply_and_block and
dbus_connection_send_with_reply,
which one I should use  for the sample code in the first email ?

2) for func dbus_message_append_args, the parm I had set is right or not?

thx a lot for you helps.
