This is a script that will allow us to generate the proper dbus messages for the pin exchange. ÂI'm not really sure how it works since I haven't read much about the dbus IPC protocol. ÂInterestingly enough, it's checked into the linux kernel tree. ÂCould this be the source to the simple-agent binary in the Âbluez tar file? http://git.kernel.org/?p=bluetooth/bluez.git;a=blob_plain;f=test/simple-agent;hb=HEAD This is the python library that is required by the simple-agent script. http://dbus.freedesktop.org/releases/dbus-python/ This works on a desktop, but we have an embedded system we are working on that does not have the python stuff installed. What I'm trying to figure out is how to create an agent that does what the python script does. One other problem I've got is that I can't get bluetoothd to generate debug output. ÂStarting it with -d, where does it write it's debug output? Â/var/log/messages? ÂDoesn't seem to. -PEM On Thu, Sep 23, 2010 at 12:46 AM, Viswanathan Sankararam <developervishwa@xxxxxxxxx> wrote: > > All, > > I am new to bluetooth and bluez.
