OpenThread is an Open Source Implementation of Thread IoT Networking Protocol

OpenThread

Thread was announced about two years ago, as a new IP-based wireless protocol based on 6LoWPAN and 802.15.4 standards and targeting IoT applications. Nest Labs,  an Alphabet company, has now released OpenThread open-source implementation of the networking protocol under a BSD license. The source code (C++)  for OpenThread includes supports for End Device, Router, Leader & Border Router roles, and  can be found on Github. The implementation is said to be OS and platform agnostic with a radio abstraction layer, have a small footprint, and implement all Thread networking layers, namely IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, and Mesh Routing. To quickly get started, you may want to read the Examples README which explains how to build the code, start two nodes, and ping them. Interestingly, while the code is there for everybody to use, only paid members ($2,500 to $100,00) of the Thread group can […]

Embedded Linux Conference 2016 and OpenIoT Summit 2016 Schedule

The Embedded Linux Conference 2016 and the OpenIoT summit 2016 will take place on April 4 – 6, 2016 in San Diego, California, and over 800 attended will meet including kernel & system developers, userspace developers, and product vendors. The Linux Foundation has recently published the schedule, so I’ve had a look at some of the talks, and designed my own virtual schedule to find out more the current development focus although I won’t attend. Monday April 4 10:40am – 11:30am – Linux Connectivity for IoT by Marcel Holtmann, Intel OTC There are many connectivity solutions that available for IoT. For example Bluetooth Low Energy, 802.15.4, Zigbee, OIC, Thread and others. This presentation will provide and overview of the existing technology and upcoming standard and how they tie into the Linux kernel and its ecosystem. 11:40 – 12:30 – BoF: kernelci.org: A Million Kernel Boots and Counting by Kevin Hilman, […]

Embedded Systems Conference 2015 Schedule – May 6-7, 2015

The Embedded Systems Conference took the name “Design West” for a couple of years, but this year, there’s no mention of Design West, and the Embedded System Conference 2015 will take place in Boston, MA, US on May 6-7, 2015. The 2-day event will have a demo hall, and well as sessions divided into 8 tracks: Connected Devices and the IoT Embedded Software Design Hardware: Design, I/O and Interfacing Prototyping Embedded Systems Design Software: Design, Languages, & Quality Fantastical Theater Teardowns The full schedule has now been posted, and I’ll build a virtual schedule with some of the sessions provided. Wednesday May 6, 2015 8:00 – 8:45 – Understanding Google/Nest Thread by Michael Anderson, Chief Scientist, The PTR Group, Inc. The IoT will live or die based on its connectivity. In examining existing wireless protocols, Google/Nest found most of them lacking. In order to address the needs for low-power wireless […]

Thread is a New IP-based Wireless Protocol Leveraging 6LoWPAN and 802.15.4 Standards

Wi-Fi is a neat way to connect devices to Internet, but it has two main inconveniences: relatively high cost and power consumption. Luckily there are standards that addresses the cost and power consumption issues. Radio chips based on IEEE 802.15.4, a standard which specifies the physical layer and media access control for low-rate wireless personal area networks, are common place and found in many existing devices relying on higher level wireless protocols such as ZigBee, ISA100.11a, WirelessHART, and MiWi. AFAIK, Zigbee is the most popular of the aforementioned protocols, but is hindered by the requirements of the license for commercial products (annual fee), Zigbee membership requirements conflict with many open source license such as GPL, and the standard suffers from lack of interoperability and IPv6 support, and power requirements that are too high for some applications. So a consortium of seven companies namely ARM, Big Ass Fans, Freescale, Nest, Samsung, […]
