Punch Through’s new Arduino board can stay wireless forever

lightblue-cortadoYou’ll have to plug in a typical Arduino-compatible board at some point in its life, whether it’s to add code or just to supply power. Not Punch Through Design’s upcoming Cortado, however. The tiny device centers on a custom Bluetooth 4.0 LE module that both enables wireless programming (including through mobile apps) and helps the board last for more than a year on a replaceable watch battery.

In fact, the Cortado will already be powered up when you get it — you can start coding before you’ve opened the shipping box. It should also be relatively flexible for its size with a built-in accelerometer and the ability to serve as an Apple iBeacon transmitter. Punch Through is crowdfunding the board with hopes of shipping its first units in May. If you’re interested, you can pledge $18 to pre-order a Cortado.

Vehicle Traffic Monitoring Platform with Bluetooth Sensors over ZigBee

The new Vehicle Traffic Monitoring Platform from Libelium allows to create real time systems for monitoring vehicular and pedestrian traffic in cities by using the new Bluetooth – ZigBee double radio feature available in the Waspmote sensor board. The platform is capable of sensing the flow of Bluetooth devices in a given street, roadway or passageway differentiating hands-free car kits from pedestrian phones. Sensor data is then transferred by a multi-hop ZigBee radio, via an internet gateway, to a server. The traffic measurements can then be analysed to address congestion of either vehicle or pedestrian traffic.

Body network spars with Bluetooth

An emerging body area network (BAN) technology is gearing up to compete with Bluetooth Low Energy across a broad range of medical and consumer applications. The competition comes as medical devices are increasingly adopting a growing set of wireless network technologies including Wi-Fi and Zigbee.

Backers of the IEEE 802.15.6 effort say the standard could be completed this year and products based on it could ship in 2012. The specification promises a range of implementations roughly on par with Bluetooth bandwidth and range but at much lower power consumption and less interference.

GE aims to use the technology in a broad range of hospital patient monitors. Since 2008, it has lobbied the U.S. Federal Communications Commission to open up spectrum in the 2.4 GHz band for such devices, replacing today’s expensive and cumbersome wired links.

Bluetooth Low Energy is Forecast to Dominate Wireless Sensor Network Market

The newly updated study, “WTRS Wireless Sensor Network Technology Trends, Q2 2010”, reviews and analyzes the available and proposed technology solutions competing for dominance in the wireless sensor network segment.

“Bluetooth Low Energy will be a significant contributor to the overall Wireless Sensor Network market, representing nearly half of all shipments in 2015”, said Kirsten West, Principal Analyst with WTRS. “Bluetooth Low Energy is designed to compete with protocols like ZigBee in applications which require infrequent and short bursts of data communication. The advantage to this new protocol is that it is totally optimized for low power battery operation.”

The WTRS Wireless Sensor Network Technology Trends Report analyzes and forecasts the market for wireless sensor networks. The report includes a thorough evaluation of emerging Wireless Sensor Network technologies and associated software including ZigBee, Bluetooth Low Energy, Wavenis, IEEE 802.15.4, Low Power WiFi, EnOcean, and others.

Libelium opens access to Bluetooth Wireless Sensor Networks

Libelium announces a new Bluetooth module for the Waspmote wireless sensor network platform. This module enables wireless sensor networks to be directly linked to portable devices such as smart phones and laptop computers. This capability is particularly useful for medical applications and for industrial diagnostics. Additionally, when combined with the Meshlium multi-protocol router, it supports the deployment of hybrid ZigBee-Bluetooth wireless sensor networks. In order to prevent interferences between both technologies, the new module uses Adaptive Frequency Hopping (AFH) to work just in free channels.
