DBus-Problem

Thu Apr 11 01:55:04 PDT 2013

Hi kumar,

Thanks for your instant help,actually i tried that yesterday it doesnt work.
Today also i tried that following is the output.

root@(none):/data/bluetooth/new/bluez_utils/bin<mailto:root@(none):/data/bluetooth/new/bluez_utils/bin># bluetoothd
root@(none):/data/bluetooth/new/bluez_utils/bin<mailto:root@(none):/data/bluetooth/new/bluez_utils/bin># ps -ae | grep bluetoothd
 1439 ?        00:00:00 bluetoothd
root@(none):/data/bluetooth/new/bluez_utils/bin<mailto:root@(none):/data/bluetooth/new/bluez_utils/bin># hcid -n
hcid[1442]: Bluetooth HCI daemon
hcid[1442]: Could not become the primary owner of org.bluez.
hcid[1442]: Unable to get on D-Bus

I dont understand why it is not running.
I am able to transfer the file from my ARM board to nokia mobile sucessfully using OPUSH profile.It doesnt require pairing.Directly i can send file using particular MAC address.

root@(none):/data/bluetooth/ob/bin# obex_test -b A0:4E:04:06:4B:C1 9
Using Bluetooth RFCOMM transport
OBEX Interactive test client/server.
> c
Connect OK!
Version: 0x10. Flags: 0x00
> p
PUT file (local, remote)> /test te
name=/test, size=6
Going to send 6 bytes
PUT successful!
Ø      q

Here file was transferred without pairing,but our team wants to send the file only after pairing.
My requirement is to generate the password for bluettoth through passkey-agent or through /etc/hcid/hcid.conf.Because my ARM board doesnt have GUI to get the workdone.
So i have to use commandline utilities.
For doing this file i did'ntstarted hcid,dbus-daemon also,then i came to know to start hcid,first we need to start dbus-daemon,so i started dbus-daemon,initially i faced some problems in starting dbus-daemon,but somome suggestions,i am able to solve that,now i am stuck here.

Both passkey-agent and hcid internally uses dbus.
I think there is a common prob;em for both the issue.But i am unable to find the issue.
Please help me regarding these

Thanks & Regards
Sandeep Gopisetty

Hi Sandeep,
This error says "bluetoothd" is not running.
Please check "ps -ae | grep bluetoothd"
If not running start bluetoothd and then try.
Regards
Aji.

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}

Hi,
My name is sandeep,currently i am working in adding bluetooth support in
ARM board.I inserted the drivers:rfcomm,btusb,bnep,bluetooth.
I cross compiled bluez-utils and all the other required utilitie.
when i am starting hcid it is giving unable to get on DBus
root@(none):/data/bluetooth/dbus/bin# hcid -n
hcid[605]: Bluetooth HCI daemon
hcid[605]: Unable to get on D-Bus

So i came to know that i have to launch dbus.I am using dbus-1.6.8 version
Following are the outputs of varioys commands
dbus-launch

root@(none):/data/bluetooth/dbus/bin# dbus-uuidgen
9a4bd04bd3d7991a146d51f3000005fd

dbus-daemon --config-file=/data/bluetooth/dbus/etc/dbus-1/system.conf

Failed to start message bus: Could not get UID and GID for
username "messagebus"

Then i created UID and GID for messagebus
 groupadd -g 101 messagebus
 useradd -u 101 messagebus

Even then also i am getting the same error
dbus-daemon --config-file=/data/bluetooth/dbus/etc/dbus-1/system.conf
