 +To communicate with the boot loader [[:tools:dfu-util|dfu-util]] can be installed and used.
 +
 +After initial installation of the boot loader and the first reset, [[:tools:dfu-util|dfu-util]] will fail to operate correctly until the mini is reset once again.

 +The first time we query the device we will get the following.
