One of the major feedback from these application is the lack of the detailed failure reasons as return for D-Bus method call, and these failure reasons can be used in metrics, optimizing retry mechanism, hinting the reproduce scenario to improve BlueZ stack. The current org.bluez.Error.* are serving the generic errors well. However,g given org.bluez.Error.* errors are used across different interface context which does not serve the detailed failure reasons well.
