Because the IoT encompasses a diverse collection of smart connected devices and capabilities, developers need to satisfy a wide range of software requirements, especially in terms of communication and security.
SEGGER has the solution to these complex requirements. Our complete software portfolio provides the solid foundation on which to built your application. With SEGGER software, you can accelerate your time-to-market with software and tools that simply work.
What is an IoT Device?
First, there is the functional side of the IoT device. This functional part is essentially an embedded system as we have known it for years. Second, IoT devices interact with each other, a server or the cloud. To achieve this, the device needs to find its counterparts; this is supported by protocols such as MQTT. The connection itself is handled via IP or UDP based protocols.
Communication increases the exposure of the IoT device, which makes it more important to keep the different aspects of security in mind during development. There are multiple ways of compromising an IoT device, therefore the use of secure components is highly recommended. Such components may include transport layer security, secure shell, digital signatures, and certificates to block out unwanted communication or snooping.
As the environment for the IoT device constantly changes, another security component is its ability to adapt to these changes. This makes it a requirement to allow in-field upgrades.
How does SEGGER support the development of IoT devices?
We offer a complete end-to-end solution. Our customers have access to a comprehensive IoT package that covers all areas from development tools to standard firmware components.
Software IP components from SEGGER, such as emSSL Transport Layer Security (TLS), emSSH Secure Shell, emSecure Digital Signature suite, emCrypt Crypto libraries, emWeb HTTP Web server, and emNet TCP/IP stack, to name a few, can be used as foundations for your securely connected IoT device. Our software works on virtually any MCU. We work with all major silicon vendors, keeping our fingers on the pulse of their latest developments to enable the next generation of designs. Take our embOS-MPU RTOS for example. This super-reliable OS works effortlessly on today's Cortex-M based MCUs and is already primed to support the next generation ARMv8-M architecture.
Connected devices requiring User Interface (UI) or Human Machine Interface (HMI) support can take advantage of SEGGER's popular graphics package emWin. Licensed by many of the top semiconductor companies, its popularity is a testament to its robustness and flexibility, perfect for implementing your custom graphical interface.
In addition to our software suites, system developers can also take advantage of SEGGER's Embedded Studio IDE, our SystemView tracing tool, and our industry-leading J-Link debug probe, all from one reliable, established vendor.
Custom IoT solutions can be developed on demand, utilizing SEGGER's embedded engineering know-how and expertise.
Example IoT Projects
The range of IoT applications is almost endless. Almost every product can be built to connect to other devices, or the internet, and to publish or receive data. We developed some projects to show how to create a "Thing". The examples were developed to demonstrate useful IoT applications. To get started, set up the hardware (usually a development board and some sensors), download the firmware, and then see what the Thing does. Want to make your products IoT-ready? Download the example projects to find out how you can create an IoT application with SEGGER Software.

The SEGGER Weather Station demonstrates how to create an IoT Node to communicate with an IoT Cloud Service. The IoT Temperature Node registers with the service and publishes its sensor data.
The data is analyzed in the cloud and made available on a website: https://weather.segger.com
The core of the project is built with embOS as the operating system to handle the different tasks, and emWin for the graphical user interface and user input.
To connect to the internet, the IoT Node uses emNet with optional WiFi support. The connection is secured with TLS, powered by emSSL.
The registration is done with the HTTP Client and JSON Parser of the IoT Toolkit. Device signatures, certificates, and verification is done with the cryptography algorithms of emCrypt.
The main communication of the IoT Node, publishing the sensor data, uses the MQTT Client, emMQTT, also secured by emSSL.
