year or so. So, in 2010, you need to:
start bluetoothd (hcid no longer exists)
hciconfig hci0 piscan
run bluetooth-agent (passkey)
initiate pairing from other device
Setup the other device to allow auto connections.
Pins in config files no longer work. On the other hand, bluetooth-agent is nice to use rom command line, and new command names actually make sense. Perhaps they will last more than a year?
