Everyone is talking about the Internet of Things (IoT). We, The Embedded Experts, provide everything to build smart embedded solutions for the IoT.
Today IoT encompasses a diverse range of smart connected devices and capabilities. This means a broad range of embedded software requirements needs to be satisfied when developers are choosing their IoT solution partner. With SEGGER you can accelerate your time-to-market with security, connectivity, reliability, 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 embOS/IP 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 the major semiconductor 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.
