Because it’s a pain, a short reminder for myself on how to connect a Bluetooth capable cell phone with a Debian box:

1. Install bluez-utils.
2. Read this (German) guide and follow instructions, but ignore the obsolete stuff about the pin helper; today it’s just an entry like passkey “1337”;
3. For whatever reason, hcid doesn’t launch a passkey-agent automatically. For the very first connection, you have to do it by yourself:
1. Get both the passkey-agent.c.gz source and its Makefile from the bluez-utils examples directory and compile it; you’ll need libdbus-1-dev.
2. Launch it as /path/to/passkey-agent 1337 HA:RD:WA:RE:AD:DR and go to a different shell.
4. cat < /dev/rfcomm0 and enter the requested pin on your cell. If nothing special happens, you’re done.

In your cell’s Bluetooth settings you could now permanently authorize your PC. The next cat < /dev/rfcomm0 shouldn’t initiate a pin request anymore.
