Updated: fixed version string and usage informations.
Updated (v2): better memory allocation checks (and no more limits for path size)
Updated (v3): update for bluez 3.9
As some of you may know, bluez 3.x dropped old pin-helper.
Now you have to use a passkey agent which communicate with hcid over dbus. And of course, kdebluetooth pin helper can't.
Probably we'll fix it in the future, with kde4 using directly dbus should be easy. In the meantime, you can use this patch i did (or this one in case you're using bluez 3.9), which transforms the "passkey-agent" contained in bluez-utils/hcid into an agent that can EXEC files, in the old way. Just download the file, go in bluez-utils build directory, than do bzcat bluez-pin-exec-patch.diff.bz2 | patch -p1 Then start it with "passkey-agent --default <your-old-pin-helper>". It will automatically exec the old pin helper when it's needed.
