read phonebook

Hello,
I have this setup:

- RPi3
- Raspbian Jessie Lite
- bluez 5.40
- ofono 1.18

in /etc/bluetooth/main.conf I set this class: 0x640408.
Using bluetoothctl I connected my phone to the SBC and I can make a call 
using the ofono tests.

I wonder how to read the contacts. I launched test-phonebook but I got 
this error:

> Method "Import" with signature "" on interface "org.ofono.Phonebook" doesn't exist

Do I need to enable something other before?
Thanks
Marco

Hi Marco,

see attached python script for how to get the phone book from a 
bluetooth device.
I think you need obexd for this, although I am not quite sure because I 
programmed
it long ago.

               Georg

I've done some work with this. Here are a few points I've learned
about dealing with PBAP.
Yes, it definitely requires obexd.   Obexd uses dbus, in session mode.
This implies that the user that runs obex must access the data in the
same session. If you want to run obexd in one shell, and access the
information from another shell, or application, you'll want to use the
system bus like so:

export DBUS_SESSION_BUS_ADDRESS="unix:path=/var/run/dbus/system_bus_socket"
You can validate that with "qdbus --system" in another session. If you
see orf.bluez.obex that you've connected it to the system dbus.

You'll also need to add dbus permissions to access via dbus, or a
non-root user won't even be able to start it.

to /etc/dbus-1/system.d/bluetooth.conf
add:
 <policy user="user">
       <allow own="org.bluez.obex"/>
       <allow send_destination="org.bluez.obex"/>
 </policy>


oh, also, the files downloaded are in vcard format. I would highly
recommend python's vobject module, or similar for ease of managing the
data.

The device needs to be paired and trusted, but it does not have to be
connected to pull PBAP information. I don't think this is important,
but I always found it interesting. All of my code written depends on
the device currently being connected though.

This isn't ofono specific stuff, so if you have any questions you can
email me off list. I also have a git repo out there with some pbap
handling.

I'd like to do more with MAP, and other obex based protocols, but time
is limited.

Jason

Hello Georg, hello Jason!
Thank you both for your interesting answers.
As far as I understand obex is now integrated in bluez5:

> https://packages.debian.org/jessie/bluez-obexd

> http://www.bluez.org/page/7/

(see Release of BlueZ 5.0)

> http://git.kernel.org/cgit/bluetooth/bluez.git/tree/doc/obex-api.txt


Thus my confusion about the test script in ofono!
So, if I'm running off-topic, I will move to the bluez mailing-list.

Anyway, following the hints of Jason I exported the dbus session address 
(because I don't use X) and set the dbus policies in bluetooth.conf. I 
paired and trusted my phone.

Running the bluez/test/pbap-client script or the Georg's code leads to:

> dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name org.bluez.obex was not provided by any .service files

while the ofono/test/test-phonebook returns:

> dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownMethod: Method "Import" with signature "" on interface "org.ofono.Phonebook" doesn't exist

Because obex is under org.bluez I don't think I need the obexd-client 
Debian package, do I?

Thanks!
Marco

I'm trying right now but it would be weird because:

https://packages.debian.org/en/jessie/bluez-obexd

"This was the software that is independent as obexd, but this has been 
integrated into BlueZ from BlueZ 5.0."

I think it just means that once it was independent and now it is part of 
bluez
but nevertheless is still delivered as an extra package.
BTW, I also have obexfs and obexftp installed, not sure if they are needed.

Yeah it works!
I apologize, but my understanding of English misled me.
I understood that the bluez-obexd package was integrated into bluez5!

Thanks a lot!
