How do I pair bluetooth devices without GUI in debian - Succulent terminal makes me stronger!

apt-get install bluez-utils dbus-1-dev make gcc

cd /usr/share/doc/bluez-utils/examples/

gzip -d passkey-agent.c.gz

make

./passkey-agent --default 1234

After that, rfcomm won't tell you "dev/rfcomm0 connection refused" or something like that when you try to enter 1234 pin on your bluetooth device.
