DLink Introduces DSP-W215 Wi-Fi Smart Plug for iOS and Android

D-Link is entering the automation market with a Wi-Fi smart plug (Model DSP-W215) that configurable via WPS, allows you to control and monitor your electrical appliance via Android 4.0+ and iOS6+ mobile devices, and it even has an overheating protection mechanism that can apparently detect if the plug or the device itself overheats. Let’s go through the technical specifications: Wi-Fi – IEEE 802.11n (According to pictures found via FCC filings, the chipset is Atheros AR1311_AL1A) Misc – Power / Status LEDs, On/Off button Dimensions – 9 x 6.10 x 3.56 cm (3.54″ x 2.40″ x 1.40″) Weight – 125 g (4.41 ounces) Power Input – 100 to 125 V AC / 5W maximum power consumption Temperature Range – Operating: 0 to 40 °C, Storage: -20 to 65 °F Humidity – Operating: 10% to 90% non-condensing, Storage: 5% to 95% non-condensing Based on these specs, since it can only work between 100 […]

$15 AsiaRF AWM002 & AWM003 Wi-Fi Modules Run OpenWRT, Expose GPIOs

This week-end I explained how to build a web server that could be used for automation and other Internet of things applications for less than $15 by combining an Arduino Leonardo with ECN18J60 Ethernet module. The hardware itself is cheap, but it may not always be convenient, or cost effective, to wire your house or office with Ethernet cables. One solution is to use Wi-Fi modules such as TI CC3000 evaluation module, an Electric Imp module, or Ariettea G25 + Wi-Fi board, but these usually cost between $30 to $50 in single quantity. AsiaRF AWM002 and AWM003 are low cost 802.11n Wi-Fi modules with access to GPIOs that could be an interesting alternative as they cost $15 + shipping, and even below $10 in quantities. The only difference between the two is that AWM003 supports more RAM (64MB vs 32MB). Here are the specifications for these modules: SoC – Mediatek/Ralink […]

Mediatek MT8639 Wi-Fi Display SoC to Support 802.11ac, NFC

Wi-Fi display technologies such as Miracast and Airplay allow you to conveniently mirror your mobile device on your TV without the needs to connect any cables, and for over about a year we’ve seen Miracast, Airplay, DLNA, and EZcast dongles on the market. In theory, this is all great, but in practice, this is all too often disappointing because of lag, sometimes the video quality is very poor, and sometimes it won’t connect. Mediatek is now working on MT8639 supporting 802.11ac which will hopefully offer a more consistent and enjoyable user experience, if your mobile device also supports 802.11ac. Here are the main features of the chip: ARM Cortex A7 @ 1 GHz Wi-Fi Dual band 2.4Ghz and 5 GHz 802.11 b/g/n/ and 802.11ac Wifi-Direct, Wi-Fi SoftAP, and Wi-Fi Bridge support Optional NFC support Wi-Fi Display – DLNA, Airplay, Miracast, “Windows” mirror Video Output – HDMI 1.4 / MHL 2.0 […]

Amlogic GPL Source Code Release – Kernel 3.10, U-Boot, and Drivers (Wi-Fi, NAND, TVIN, Mali GPU)

Last month, I noticed Amlogic provided links to the Android SDK for S802 / M802 on their open source website, but the only way to get the source was to share your SSH public with Amlogic, so that they give you access. It did not happen, but the company has released the source for Linux 3.10.10, U-boot 2011.03, Realtek and Broadcom Wi-Fi drivers, NAND drivers, “TVIN”drivers, and kernel space GPU drivers for Mali-400 / 450 GPU. There are also some customer board files for Meson 6 only (AML8726-MX / M6) but they do not seem to match the kernel… If you want to build the kernel, including the drivers, you’ll need to download a bunch of files: wget http://openlinux.amlogic.com:8000/download/ARM/kernel/arm-src-kernel-2014-03-06-d5d0557b2b.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/rtk8192du-2014-03-06-7f70d95d29.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/rtk8192eu-2014-03-06-9766866350.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/rtk8192cu-2014-03-06-54bde7d73d.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/rtk8188eu-2014-03-06-2462231f02.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/brcmap6xxx-2014-03-06-302aca1a31.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/wifi/wifi-fw-2014-03-06-d3b2263640.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/modules/aml_tvin-2014-03-06-fb3ba6b1c8.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/modules/aml_nand-2014-03-06-39095c4296.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/customer/aml_customer-2014-03-06-76ce689191.tar.gz wget http://openlinux.amlogic.com:8000/download/ARM/gpu/gpu-2014-03-06-0425a1f681.tar.gz You’ll need to extract these tarballs in specific directories:

Atmel Introduces ARM Cortex M0+ based SmartConnect Wi-Fi Modules and SmartConnect Zigbee SoCs

In order for the Internet of Things to take off, wireless connectivity solutions with ultra low power, lost cost, and small footprint are needed. Atmel seems to have made a step in the right direction by launching SmartConnect Wi-Fi modules and Zigbee SoCs featuring an ARM Cortex M0+ core. SmartConnect Wi-Fi does not appear to be a single chip solution, but instead Atmel has created a family of Wi-Fi modules integrating the company’s ultra-low power Wi-Fi SoChip with an ARM Cortex M0+ based MCU. These modules will enabled battery-powered Wi-Fi connectivity for IoT endpoints such as thermostats, and temperature sensors in a cost effective way. The company will provide a software solution with application and security protocols such as TLS, TCP/IP stack and an RTOS, all of which can be downloaded via Atmel Studio 6 Integrated Development Platform (IDP). SmartConnect ZigBee SAM R21 combines an ARM Cortex M0+ core with […]

802.11ah Wi-Fi (900 MHz) to Provide Low Power, Long Range Connectivity for the Internet of Things

Most devices now feature Wi-Fi modules capable of handling 802.11 b/g/n at 2.4 Ghz (and 5 GHz for dual band Wi-Fi), and newer devices and routers boast 802.11ac connectivity @ 5GHz with increased bandwidth (up to 1.2 Gbit/s in theory, maybe around 400 Mbit/s in practive), and in some case increased range with  beam-forming. But thanks to an article on EETimes, I’ve learned there’s another upcoming Wi-Fi standard called 802.11ah operating in the 900MHz range, with data rates from 150 Kbit/s with a 1 MHz band to as much as 40 Mbit/s over an 8 MHz band, lower power consumption, and a least double of the range of a typical 802.11n device,capable of covering an area of about 1 km2. The target applications are sensors networks, backhaul networks for sensor and meter, and extended range Wi-Fi, as the standard allows long range and more clients at low bitrates. This new […]
