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.

Hello,
many thanks for the hints.

Neither. The reason was somewhere else.
ltib configures bluez with prefix /usr , but moves some config
files/directories from /usr/etc to /etc . When I added dbus manually to
ltib, I ran configure with /usr , too, but without realising that then
dbus would not find the bluetooth related config file in
/usr/etc/dbus-1/system.d/, because ltib would have moved it to
/etc/dbus-1/system.d/.
Solution: make sure that bluez and dbus use the same configuration
directories and that they are compiled with the same prefix.
One step further. More problems expected.

I think one of the following cases are possible:
1. An earlier hcid is already running. Check ps ax | grep hcid to confirm.
or
2. You are not root while running hcid .
HTH.
