Have you tried following the Gentoo wiki? You're probably not using
Gentoo, but they are well-known for providing pretty good documentation
to the open source community.

About the PIN code: have you configured a pin helper correctly in
hcid.conf? It's pretty simple, you can just write a shell script:

#!/bin/sh
echo "PIN:1234

Make it executable, then edit hcid.conf with the line:

pin_helper /path/to/the/script
