i want to access the contacts of my smartphone over bluetooth. This should be made as first step of a project of my with a raspberry pi. I read something about the phone bok access protocol (PBAP). But all i could was not very helpful for me. The most examples i found where to old.

I already managed to pair and connect my smart phone (OnePlus One). I also can see that is support PBAP. I use bluez in version 5.23-2+rpi1.

I found two examples of an PBAP client, one from obexd (http://code.metager.de/source/xref/linux/bluetooth/obexd/test/pbap-client) and one from bluez (http://code.metager.de/source/xref/linux/bluetooth/bluez/test/pbap-client).

If i execute the obexd example on the pi i get the following error:

Creating Session
Traceback (most recent call last):
  File "pbap-client-obexd.py", line 110, in <module>
    session_path = client.CreateSession(sys.argv[1], { "Target": "PBAP" })
  File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 70, in __call__
    return self._proxy_method(*args, **keywords)
  File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 145, in __call__
    **keywords)
  File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 651, in call_blocking
    message, timeout)
dbus.exceptions.DBusException: org.bluez.obex.Error.Failed: No adapter found

If i execute the bluez example i get the following error:

Creating Session
Traceback (most recent call last):
  File "pbap-client-bluez.py", line 128, in <module>
    session_path = client.CreateSession(sys.argv[1], { "Target": "PBAP" })
  File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 70, in __call__
    return self._proxy_method(*args, **keywords)

    **keywords)
  File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 651, in call_blocking
    message, timeout)
dbus.exceptions.DBusException: org.freedesktop.DBus.Error.UnknownObject: Method "CreateSession" with signature "sa{ss}" on interface "org.bluez.obex.Client1" doesn't exist

Does anyone of you have an idea to fix it, an actual tutorial or an other example?

Thank you

After searching a few hours later, i found a python library called PyOBEX. It contains some examples, e.g. a PBAP-Client, a example to download files over bluetooth and much more. It also contains all methods for pairing and connecting. Works on first try for me.

PyOBEX is the right choice. you can also have a look into pypbap which has both pbap client and server built on top of PyOBEX. And has nice REPL to playaround with all pbap functionalities.
