The |smp| is responsible for performing a Device Firmware Upgrade (DFU) over Bluetooth® LE.

You can perform the DFU using for example the `nRF Connect for Mobile`_ application.
The :guilabel:`DFU` button appears in the tab with the connected Bluetooth® devices.
After pressing the button, you can select the :file:`*.bin` file that is to be used for the firmware update.
