Either using mgmt API to do pairing (see mgmt_create_bonding() in
src/mgmt.c from bluez sources and doc/mgmt-api.txt for how to do this)
or increase socket security level to at least medium using
setsockopt() (see set_sec_level() in btio/btio.c for how to do this).

In summary, you will need to use BlueZ code as reference if you want
to do these things on your own. The easier route is to use BlueZ D-Bus
API to do pairing.
