The following picture illustrates a screenshot of the hawkBit's console. This interface allows to configure the update policies for the entire fleet of devices and to monitor the past, current, and scheduled roll-out operations. Several options are available, for example for defining different policies on a geographical basis.

This specific screenshot shows several attempts to deploy the software to the target. Some of them were completed successfully, some were not. For instance, to verify the capability of the target to resume an interrupted updating, the gateway was turned off abruptly in the middle of downloading or flashing.

To test the overall remote update mechanism, appropriate images have to be prepared. Such images include a file listing platform-dependent operations required to apply the update on the device side. This file is processed by SWUpdate that carries out such operations.
