DBus-Problem

Thu Apr 11 01:12:03 PDT 2013

Hi

Unable to get on D-Bus message is coming when i run hcid -n because function call input_dbus_init() is failing.

In input_dbus_init function:connection = init_dbus("org.bluez.input", NULL, NULL);
In init_dbus("org.bluez.input", NULL, NULL); Control is going to the following code and it is generating the message :

The name org.bluez was not provided by any .service files
if (dbus_bus_request_name(conn, name, 0, &err) !=
    DBUS_REQUEST_NAME_REPLY_PRIMARY_OWNER ) {
   error("Could not become the primary owner of %s.", name);
   return NULL;
  }

For Passkey-agent, I verified the source code Passkey-agent.c,from which the error message is getting.

root@(none):~# passkey-agent default 1000
Can't register passkey agent --------------------------------------------------->this is getting because(Please see below ----)
The name org.bluez was not provided by any .service files

dbus_connection_send_with_reply_and_block(conn, msg, -1, &err);-------->This API is failing due to which the wrrir message is generated.

Code is actually checking the return value of the above API,and if it is -1 it is generating the error message.

Please tell what to do also hcid -n is failing.
Please help me.

Thanks & Regards
Sandeep

Apologize for not sending to the mailing list in the first place.

It looks like you've got all your service and policy files missing or wrong.  Check where you system.conf file points to find service and additional policy (configuration) files.

Hi Krzysztof Konopko

Thanks for your immediate reply
Previous issue was solved,ehen I manually added message group in /etc/group and user in /etc/shadow.
Now I am able to run dbus-daemon -system.

Now I am stuck with the following

Even the D-BUS is running hcid -n is giving the same error

hcid[1710]: Bluetooth HCI daemon
hcid[1710]: Could not become the primary owner of org.bluez.
hcid[1710]: Unable to get on D-Bus

Then I ran passkey-agent (an utility to generate the password commandline),it is also giving the error related to d-bus

root@(none):~# passkey-agent default 1000
Can't register passkey agent
The name org.bluez was not provided by any .service files

Please help me and provide me some solution.I am in very much need to do this.

Thanks & Regards
Sandeep Gopisetty

Hi Sandeep,

On your system, could you check the following:
id messagebus

And if there's no `id' utility on your system:
grep messagebus /etc/{passwd,group}
