Thanks for your comment. > It seems to me that all the events and value changes result in DBus messages around. You can watch them with dbus-monitor first, and write your own app listening and filtering them later. I will play with this idea but I am unsure if any dbus messages make it into userspace before a characteristic interaction takes place.
