Google Announces LoWPAN/Thread Support in Android Things DP 6.1

Not to be confused with LPWAN (Low Power Wide Area Network), LoWPAN (Low Power Wireless Personal Area Network) solutions are designed for peer-to-peer usage on constrained battery-powered devices using standard procotols like HTTP and CoAP. Based on 6LoWPAN and 802.15.4, Thread is one of those LoWPAN standards,  and Google has just added API support for configuring and managing LoWPAN as a part of Android Things Developer Preview 6.1, including networking support for Thread. Google explains “these types of low-power connectivity solutions enable Android Things devices to perform edge computing tasks, aggregating data locally from nearby devices to make critical decisions without a constant connection to cloud services”. You can read LoWPAN API guide to learn more details on building your own apps to create and join local mesh networks, but to quickly get started OpenThread running on Nordic Semi RF52840-PDK is recommended. You’ll first need to install the firmware and LowWPAN NCP user driver as explained in Github, and then …

FOSDEM 2017 Open Source Meeting Schedule

FOSDEM (Free and Open Source Software Developers’ European Meeting) is a 2-day free event for software developers to meet, share ideas and collaborate that happens on the first week-end of February, meaning it will take place on February 4 & 5, 2017 this year. FOSDEM 2017 will features 608 speakers, 653 events, and 54 tracks, with 6 main tracks namely: Architectures, Building, Cloud, Documentation, Miscellaneous, and Security & Encryption. I won’t be there, but it’s always interesting to look at the schedule, and I made my own virtual schedule focusing especially on talks from “Embedded, mobile and automotive” and “Internet of Things” devrooms. Saturday 4, 2017 11:00 – 11:25 – Does your coffee machine speaks Bocce; Teach your IoT thing to speak Modbus and it will not stop talking, by Yaacov Zamir There are many IoT dashboards out on the web, most will require network connection to a server far far away, and use non standard protocols. We will show …

FOSDEM 2016 Schedule – Open Source Hardware and Software Event in Europe

FOSDEM (Free and Open Source Software Developers’ European Meeting) is a 2-day event that usually takes place on the first week-end of February in Brussels, but this year it will be on January 30-31. The event brings thousands of developers, hackers, and other person interested in open source technology who present their projects and share ideas. FOSDEM 2016 schedule is now available, and There will be 557 speakers, 612 events, and 50 tracks this year including 7 main tracks: Distros, Enterprise, Hardware, Communications, Miscellaneous, Office, Systems Administration, and Virtualization. So I’ve had a look at some of the talks, especially out of  “Embedded, Mobile and Automotive” and “IoT” devrooms, and prepared my own virtual schedule although I won’t be able to attend. Saturday 10:30 – 10:55 – MIPS, the other side of the embedded by Alexjan Carraturo For many years MIPS processors have been involved in the embedded market, particularly in areas related to networks and storage.

ARM TechCon 2014 Schedule – 64-Bit, IoT, Optimization & Debugging, Security and More

ARM Technology Conference (TechCon) 2014 will take place on October 1 – 3, 2014, in Santa Clara, and as every year, there will be a conference with various sessions for suitable engineers and managers, as well as an exposition where companies showcase their latest ARM based products and solutions. The detailed schedule for the conference has just been made available. Last year,  there were 90 sessions organized into 15 tracks, but this year, despite received 300 applications,  the organizers decided to scale it down a bit, and there will be 75 session in the following 11 tracks: Chip Implementation Debugging Graphics Heterogeneous Compute New Frontiers Power Efficiency Safety and Security Software Development and Optimization Software Optimization for Infrastructure and Cloud System Design Verification There are also some paid workshops that take all day with topics such as “Android (NDK) and ARM overview”, “ARM and the Internet of Things”, or “ARM Accredited Engineer Programs”. As usual, I’ve gone through the schedule …

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, Silicon Labs, and Yale Security, have come together to start …

Thingsquare Mist – Open Source Firmware for The Internet of Things

Thingsquare recently released the source code for the Thingsquare Mist firmware, an ultra lightweight router software (<4 kB memory) for the Internet of Things based on open Internet standards such as IPv6, RPL (Routing Protocol for Lossy networks), and 6lowpan. Thingsquare Mist allows to connect battery-powered wireless micro-controllers to the Internet, and is currently used in applications such as smart light bulbs, connected home appliances, and connected cities. The IPv6 mesh network is composted of nodes with a low power radio that communicate with the Mist router (Green), which in turn connect to the Internet and Thingsquare Cloud backend (Thingsquare Haven) to store the data, and/or receive control commands via Ethernet or Wi-Fi. The end users can then use an App to monitor, and/or control the devices remotely. Thingsquare Mist uses IETF RPL IPv6 mesh routing protocol (pronounced “ripple”) for IPv6 nodes communications. Thingsquare Mist runs on several low-power wireless SoCs, standalone MCUs, as well as low-power wireless transceiver combos, …
