		Download file from File System
		******************************

		SMP server supports downloading files from File System on device via
		:file:`mcumgr`. This is useful with FS log backend, when files are stored in
		non-volatile memory. Build and flash both MCUboot and smp_svr applications and
		then use :file:`mcumgr` with :file:`download` command, e.g.:

		.. code-block:: console

		mcumgr --conntype serial --connstring='dev=/dev/ttyACM0,baud=115200' \
		fs download /lfs/log.0000 ~/log.txt
