After running into PBAP profile issues with BlueZ, this stackoverflow post [Phone Book Access (PBAP) client for Linux (Raspberry Pi)] suggested trying [PyOBEX].
Install the Python library.
sudo pip install PyOBEX
The [PyOBEX] repository needs Mecurial.
sudo apt-get install mercurial
Clone the examples.
hg clone https://user@bitbucket.org/dboddie/pyobex
