##########################################
5+
6+
Overview
7+
********
8+
The Sentrius™ MG100 Gateway offers a compact, out of box Bluetooth to low power cellular gateway
9+
solution.
10+
11+
Based on the Pinnacle 100 socket modem, the Sentrius™ MG100 gateway captures data from any
12+
Bluetooth 5 modules or devices and sends it to the cloud via a global low power cellular
13+
(LTE-M/NB-IoT) connection. The MG100 seamlessly incorporates a powerful Cortex M4F controller,
14+
full Bluetooth 5 connectivity, and dual-mode LTE-M/NB-IoT capabilities. The MG100 has full regulatory
15+
and network certifications and End Device carrier approvals.
16+
17+
Develop your application directly on the integrated Cortex M4F microcontroller using Zephyr RTOS,
18+
enabling your application development with a secure, open source RTOS with more than just kernel
19+
services. Remotely debug your fleet of devices with the `Memfault Platform`_. Take advantage of the
20+
Zephyr community and Laird Connectivity’s multi featured Out of Box (OOB) sample source code
21+
covering all aspects of the product's capabilities and hardware interfaces. The MG100 also delivers
22+
complete antenna flexibility with internal or external antenna options available, and the optional
23+
battery backup provides uninterrupted reporting of remote Bluetooth sensor data.
24+
25+
More information about the board can be found at the `MG100 website`_.
26+
27+
The MG100 hardware provides support for the Nordic Semiconductor `nRF52840`_ ARM Cortex-M4F CPU,
28+
`Sierra Wireless HL7800`_
29+
and the following devices:

Programming and Debugging
159+
*************************
160+
161+
Applications for the ``mg100`` board configuration can be
162+
built and flashed in the usual way. (see :ref:`build_an_application`
163+
and :ref:`application_run` for more details)
164+
165+
The `Laird Connectivity USB-SWD Programming Kit`_ contains all the necessary
166+
hardware to enable programming and debugging an MG100.
167+
168+
Flashing
169+
========
170+
171+
Follow the instructions in the :ref:`nordic_segger` page to install
172+
and configure all the necessary software. Further information can be
173+
found in :ref:`nordic_segger_flashing`. Then build and flash
174+
applications as usual (see :ref:`build_an_application` and
175+
:ref:`application_run` for more details).
176+
177+
Here is an example for the :ref:`hello_world` application.
178+
179+
First, run your favorite terminal program to listen for output.
180+
181+
.. note:: On the MG100,
182+
the USB connector should be used to access the UART console.
183+
184+
.. code-block:: console
185+
186+
$ minicom -D <tty_device> -b 115200
187+
188+
Replace :code:`<tty_device>` with the port where the board MG100
189+
can be found. For example, under Linux, :code:`/dev/ttyUSB0`.
190+
191+
Then build and flash the application in the usual way.
192+
193+
.. zephyr-app-commands::
194+
:zephyr-app: samples/hello_world
195+
:board: mg100
196+
:goals: build flash
197+
198+
Debugging
199+
=========
200+
201+
Refer to the :ref:`nordic_segger` page to learn about debugging Nordic boards with a
202+
Segger IC.
203+
204+
Software
205+
********
206+
207+
MG100 Out-of-Box Demo Software
208+
==============================
209+
The MG100 ships with an out of the box software demo.
210+
Check out the `BLE Gateway OOB Demo`_ source code and documentation.
211+
212+
Testing Bluetooth on the MG100
213+
==============================
214+
Many of the Bluetooth examples will work on the MG100.
215+
Try them out:
216+
217+
* :ref:`ble_peripheral`
218+
* :ref:`bluetooth-eddystone-sample`
219+
* :ref:`bluetooth-ibeacon-sample`
220+
221+
Testing the LEDs and buttons in the MG100
222+
====================================================
223+
224+
There are 2 samples that allow you to test that the buttons (switches) and LEDs on
225+
the board are working properly with Zephyr:
226+
227+
.. code-block:: console
228+
229+
samples/basic/blinky
230+
samples/basic/button
231+
232+
You can build and flash the examples to make sure Zephyr is running correctly on
233+
your board. The button and LED definitions can be found in
234+
:zephyr_file:`boards/arm/mg100/mg100.dts`.
