Hello! Everyone .I have compile bluez-libs-3.11 and bluez-utils-3.11 in scratchbox for arm . I could use hcitoll scan to find devices and sdptool to find services after I ran hciconfig hci0 up. But when I ran hcid -n after start dbus-daemon --system,error happened. [root@(none) /]# hcid -n hcid[481]: Bluetooth HCI daemon hcid[481]: Can't connect to system message bus: Did not receive a reply. Possibl e causes include: the remote application did not send a reply, the message bus s ecurity policy blocked the reply, the reply timeout expired, or the network conn ection was broken. hcid[481]: Unable to get on D-Bus I think maybe the dbus was not configure properly.I also compile it in scratchbox for arm. I have changed --localstatedir=/var --sysconfdir=/etc,and also made a link in /etc/ to /var/bluetooth and a link dbus-1 in /etc to /var/dbus-1 because my file system is scram format,files can be read only in the flash,only the var directory can be changed. Can someone help me? I have no idea now though searching google so long time. Wang Jimscen Jun 14,2007
