Hello,

This topic has already come up several times, but the respective answers 
did not solve the problem for me. What happens is:

mx27# /usr/bin/dbus-daemon --system
mx27# /usr/sbin/hcid -n -f /etc/bluetooth/hcid.conf
hcid[1869]: Bluetooth HCI daemon
hcid[1869]: Could not become the primary owner of org.bluez
hcid[1869]: Unable to get on D-Bus

Below some more details about the build process and the configuration 
files. My feeling is that the dbus daemon does not read the bluetooth 
related settings.

Many thanks for your help in advance,
peter.
