Open Source Foundries IoT Zephyr, Linux, IoT Gateways, Bluetooth Mesh microPlatforms demo

Posted by Charbax – October 10, 2017

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.
