Connect Objects Wirelessly, and Create User Interfaces Easily With Xped DeB for Arduino (Crowdfunding)

Xped, an australian startup, has designed an ecosystem comprised of an Arduino shield with NFC and 802.15.4 connectivity, a Raspberry Pi Model B+ based gateway, and DeB browser that generates a user interface in Android, iOS, or Linux based on an XML file stored in an Arduino board. This allows to connect various objects wirelessly, with reduced power consumption thanks to 802.15.4, and to create user interfaces easily with a text file located in your Arduino board. ADRC stands for Auto-Discovery Remote Control, and that’s what Xped ADRC Shield allows thanks to the following hardware specifications: MCU – RM Cortex M3 32-bit microcontroller with 256 KB of FLASH memory. NFC – NDEF Type-2 Tag with bi-directional communications capability. NFP proximity communications technology which is similar to NFC but was developed by Xped to use less than 1,000th of the power and provide faster speeds than NFC. It is mainly used […]

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, […]

Wireless Networking with IEEE 802.15.4 and 6LoWPAN – ELCE 2012

Alan Ott, founder of Signal 11 Software, gives a presentation dealing with wireless networking for the internet of things in Linux, especially with 802.15.4 and 6LoWPAN standards at the Embedded Linux Conference in Barcelona, Spain on November 5, 2012. Abstract: With the rise of the internet of things, low-power wireless devices will become increasingly prevalent. IEEE 802.15.4 is a wireless networking protocol designed for low-power and low-data-rate devices, such as those used in wireless sensor networks. While some higher layer protocols based on 802.15.4 are proprietary, an open standard called 6LoWPAN enables IPv6 traffic over 802.15.4. This presentation will give overviews of 802.15.4, its status in the Linux kernel, hardware support, comparison with other wireless protocols, and a demonstration of a simple 802.15.4/6loWPAN network. This presentation is targeted toward developers who wish to create low-power, low-data-rate wireless networks for sensors or other applications. Attendees can expect to gain a basic […]
