Nordic Semiconductor provides ultra-low power (ULP) wireless chips that can run for a long time from small power sources, like watch batteries. NORDIC the latest version of Bluetooth is Bluetooth5 by NORDIC .It represents the greatest advancements in the specification since Bluetooth 4.0 and the introduction of Bluetooth Low Energy. Errata High throughput, Long range, advertising extensions, increased broadcast capacity, improved co-existence. IEEE 802.15.4: is a standard for low data rate, low power networks. IEEE 802.15.4 defines the physical (PHY) and Medium Access Control (MAC) layers and forms the basis for numerous upper layer networking specifications including Thread, 6LowPAN, Zigbee and Wireless HART. IEEE 802.15.4 is supported by the Nordic nRF52840 multi-protocol SoC. Thread is a standards-based IPv6-based mesh networking protocol developed for simply and securely connecting products around the home to each other, to the internet and to the cloud. Cellular IoT (A low power LTE-M and NB-IoT solution for wide area network deployments). The LTE-M and NB-IoT standards are open standards created by 3GPP to allow wide deployment of IoT nodes while leveraging existing cellular infrastructure. The LTE protocols are designed for unparalleled scalability in number of nodes while maintaining good Quality of Service. Both technologies offer eDRX and PSM which are techniques for lowering the power consumption compared to traditional LTE. In eDRX, device and network agree exact times when the device will be ready to receive data.

Nordic Semiconductor's Bjørn Kvaale shows the latest cellular IoT NB-IoT, LTE-M, GPS and BLE Bluetooth 5.1 Direction Finding, Zigbee and Thread solutions for development on the market today. Showing their Bluetooth Low Energy solutions including the newly launched nRF5340 SoC featuring dual Arm Cortex-M33 processors, truly secure, with two flexible processors, the advanced feature set, and an operating temperature up to 105 °C, makes it the ideal choice for professional lighting, advanced wearables, and other complex IoT applications The nRF5340 PDK is the preview development kit for the nRF5340 SoC, containing everything needed to get started with development, on a single board. The PDK supports development with an extensive range of wireless protocols. It supports Bluetooth Low Energy, including the Long Range and high-speed 2 Mbps features. Mesh protocols like Bluetooth mesh, Thread and Zigbee can be run concurrently with Bluetooth LE, enabling smart phones to provision, commission, configure and control mesh nodes. NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are also supported. The PDK is bundled with an NFC antenna that quickly enables testing of nRF5340’s NFC-A tag peripheral. A SEGGER J-Link debugger is on the board, enabling full-blown programming and debugging, of both the nRF5340 SoC and external targets. All analog and digital interfaces, and GPIOs are available via headers and edge connectors. The kit is Arduino Uno Rev3 hardware compatible, meaning it can be easily interfaced with external device shields, including the Power Profiler Kit. Four buttons and four LEDs simplify input and output to and from the nRF5340 SoC, they are all user-programmable. An on-board external memory is connected to the 96 MHz QSPI peripheral in the nRF5340 SoC. The PDK is typically powered with USB, but can be powered by a wide range of sources, within the supply range of 1.7 to 5.0 V. In addition to USB, it can be powered with external source, but also includes a CR2032 battery holder and a Li-Po battery connector, for in-field testing. Current consumption can be measured by using the dedicated current measurement pins. The nRF Connect SDK is the software development kit for the nRF5340 SoC, and it has board support for the nRF5340 PDK.
In this demo, the Trusted Firmware M is providing the SPE and JWT sign, Zephyr is providing the NSPE and The Google IoT application is running on Zephyr using secure services from Trusted Firmware M.
- Platform Security Architecture (PSA) is an IoI security framework being developed by Arm.
- Trusted Firmware M (TF-M) is an open source project to provide PSA compliant secure firmware for M profile devices.
- Zephyr is a Linux Foundation Collaboration Project to provide a small, scalable RTOS for connected, resource constrained device.
- Arm Musca-A1 subsystem based on Armv8-M which allows partitioning the SW execution in Secure and Non Secure domain.

Open Source Foundries is a spin off company off of Linaro, composed of a talented group of engineers to work more directly with companies, OEMs, ODMs, small, medium to large companies to bring new open source products and solutions more rapidly to the market. Leveraging all the work done by Linaro and speeding up the time to market, enable rapid product development, here demonstrating some of the open source IoT solutions provided based on Zephyr on ARM Cortex-M and Linux on ARM Cortex-A using the Linaro Technologies Division (LTD) microPlatforms system.
The lack of a secure IoT solution has the industry scrambling. The Open Source Foundries team believes that a world can exist in which all connected devices can be secured and updated in a timely fashion. In this demonstration shown at the Linaro Connect San Francisco 2017, the team showcases its secure end to end FOTA (firmware over the air) solution implementing the latest in connected technologies.
At Open Source Foundries, software is their passion, hacking hardware is their favorite past time, so they have created the OSLight project to convert off the shelf hardware into secure connected devices. They have inserted a Red Bear NRF52 BLE Nano 2 into these lamps, to allow them to communicate over BLE with various cloud services. In the first demo, they demonstrate creating a secure BLE mesh network with these lamps. They show the ability to securely pass messages through the mesh network to control the state of the LED lamp. The next demo shows a set of 96Boards Nitrogens sending temperature data to the SoftBank IoT Cloud with the ONEM2M protocol using 6lowpan over BLE. The third and final demo introduces a variant of the OSLight project, a fully 3D printed light bulb. Instead of a simple LED array it has a 12 LED WRGB NeoPixel which is powered by line voltage, stepped down to 5VDC.
For microcontrollers, they offer their Zephyr microplatform, an open source software reference based on Zephyr RTOS and MCUboot. This software stack implements secure boot, unified microkernel, and IP (TCP or UDP) using 6lowpan over BLE. At the protocol level they've embraced industry standards such as LWM2M/ONEM2M/HTTPS/MQTT to provide an array of options for their customers, whilst ensuring no vendor lock in. Open Source Foundries subscribers are offered continuous validated software updates throughout the life of their product for a fixed monthly subscription fee.
On the gateway, they offer their Linux microplatform, which is again, an open source reference based on the latest Linux kernel version, and a minimal Yocto based userspace with a container runtime (Docker). By isolated the OS from the containers, each can be updated independently while providing limitless potential for the applications it can run. For updates they again implement standards, and stay vendor neutral to allow their customers to choose the solution that is right for them. Continuous validated updates for the OS and containers are also offered for this platform for a reasonable fixed monthly fee.
