Device Management
#################
Overview
********
The management subsystem allows remote management of Zephyr-enabled devices.
The following management operations are available:
* Image management
* File System management
* Log management (currently disabled)
* OS management
over the following transports:
* BLE (Bluetooth Low Energy)
* Serial (UART)
The management subsystem is based on the Simple Management Protocol (SMP)
provided by `MCUmgr`_, an open source project that provides a
management subsystem that is portable across multiple real-time operating
systems.
The management subsystem is split in two different locations in the Zephyr tree:
* :file:`ext/lib/mgmt/mcumgr/` contains a clean import of the MCUmgr project
* :file:`subsys/mgmt/` contains the Zephyr-specific bindings to MCUmgr
Additionally there is a :ref:`sample <smp_svr_sample>` that provides management
functionality over BLE and serial.

Command-line Tool
*****************
MCUmgr provides a command-line tool, :file:`mcumgr`,for managing remote devices.
The tool is written in the Go programming language.
Installation information can be found in the `MCUmgr command-line tool`_
section of the `MCUmgr documentation`_. A full rundown of the necessary commands
to perform Device Firmware Upgrade is located in
`MCUmgr command-line tool examples`_, and a practical step-by-step guide to DFU
using MCUmgr can be found in :ref:`smp_svr_sample`.
Bootloader integration
**********************
The :ref:`dfu` subsystem integrates the management subsystem with the
bootloader, providing the ability to send and upgrade a Zephyr image to a
device.
Currently only the MCUboot bootloader is supported. See :ref:`mcuboot` for more
information.
