PIN (or passkey) management --------------------------- since bluez 3.0 the old pin_helper script has been replaced by the dbus interface. To add a default passkey for every outgoing request (e.g. the old /etc/bluetooth/pin file) drop it into /etc/bluetooth/passkeys/default. (e.g. echo -n "1234" > /etc/bluetooth/passkeys/default ) To add a passkey for a specific outgoing connection replace default with the device's address. ( /etc/bluetooth/passkeys/aa:bb:cc:dd:ee:ff will contain passkey for aa:bb:cc:dd:ee:ff ). After adding a passkey you should restart bluetooth with /etc/init.d/bluetooth restart and the new passkeys will be registered. (This behaviour has been copied from Debian)
