Get to Know About Your S100

1.1. Product Overview

The TRITOM Azure Sphere Guardian S100, with Microsoft Azure Sphere-certified chip includes built-in Microsoft security

technology, can provide connectivity and a dependable hardware-based root of trust. The TRITOM S100 provides various

interface for unconnected equipment which was designed before connectivity for non-IT devices was considered feasible or

were intentionally not connected because they were deemed too mission critical to be subjected to the unsafe internet world.

Connecting equipment and device to the internet representing innovative business model such as preventive maintenance, just-

in-time reporting and role-based access to the equipment and data. The TRITOM S100 can be deployed in the following indoor

IoT applications and scenarios.

Get Started to Develop Your S100

2.1 Quickstarts to setup your S100

2.1.1 To develop your own TRITOM S100 application, please refer to: https://docs.microsoft.com/en-

us/azure-sphere/install/overview for reference.

2.1.2 S100 is a LTE connectivity device, please also prepare your IoT LTE SIM which is activated with data

service. Our suggestion SIMs are Cat.M, Cat.M1 or Cat.4.

SIM corresponding to LTE module

Cat.M : Quectel BG96

Cat. 1 : Quectel EC21-E/EU, Telit LE910C1-NF

Cat. 4 : Quectel EC25

2.1.3 Disassemble Your S100. Please follow the steps to disassembling the enclosure of S100:

2.1.2 Insert your SIM card.

2.1.2.1 After disassembling, the SIM card slot is in the backside of the PCBA as showed below.

2.1.2.2 Insert the SIM card (4FF, nano SIM).

2.1.2.3 Power on, then check the LTE connection status by LED. Check the LTE connection, please refer to

the LED table <Table 1>

2.2 Preparation for Software Development Environment

2.2.1 Microsoft Installation Instructions. Detailed guidance is provided at:

https://docs.microsoft.com/en-us/cli/azure/

2.2.2 Verify Windows 10 Version

2.2.2.1 Before starting software installation, verify the version of Windows 10 Operating System meets

requirements. In the Windows search box (Windows key + R), enter winver to check...

2.2.2.2 The version reported must be 1607 or later

2.2.3 Install Azure Sphere SDK

2.2.3.1 Download and unzip the latest Microsoft Azure Sphere SDK from: https://reurl.cc/R6ljyx

2.2.3.2 Install this SDK on a Windows 10 computer, using the instructions located at:

http://avnet.me/ms_sphere_docs

2.2.3.3 Once installed, launch the application and at the Azsphere command prompt, enter this

command to confirm the Sphere SDK version: azsphere show-version. The version reported should be

19.02 or later

2.2.4 Claim your device

Detailed guidance is provided at: https://reurl.cc/l0r0Z9

Every device must be "claimed" into an Azure Sphere tenant. Claiming the device associates its unique,

immutable device ID with your Azure Sphere tenant. The Azure Sphere Security Service uses the device ID

to identify and authenticate the device.

Software Development Introduction

3.1 Introduction (MT3620/MT7688 AT-Command)

3.1.1 Block diagram

3.1.2 Serial Port Configuration for MT7688 UART 02

● Baud Rate: 115200

● Data bits: 8

● Parity Check: None

● Stop bit: 1

● Flow control: None

“User App” is an application program running on MT3620, which uses AT-command at

chapter 3.2 to communicate with “gemtekMonitor”.

“gemtekMonitor” is a daemon running at MT7688, which handles AT commands from

MT3620, and gives responses respectively. Please refer to chapter 3.2 to see the

command details. When “gemtekMonitor” gets ready, it will send “+ROUTER_READY” to

MT3620.
