Hi Marcel, I'm not familiar with the dynamic_debug feature. On ChromiumOS, the interface proposed here is used by the user feedback system to allow the collection of BT_DBG output when the user is trying to send us feedback. If there is a better way to do this, we can certainly use that. but may need to be pointed in the right direction.
