ON Semiconductor has introduced the Connected Lighting Platform, leveraging the company's expertise in Power over Ethernet (PoE) and ultra-low-power Bluetooth® Low Energy connectivity, along with AC/DC and DC/DC power conversion design.   The prototyping platform enables engineering teams to explore and innovate in the connected lighting sector, where light fittings become part of the Internet of Things (IoT). The Connected Lighting Platform features multiple forms of connectivity for ...
With almost all modern smartphones featuring RFID readers, RFID tags are becoming more prevalent in our everyday lives, and they can be found on food packaging, anti-theft devices, shipping containers, and everything else in between, but engineers at the Massachusetts Institute of Technology have found a new use for these increasingly more common electrical devices: Cheap chemical sensors.     (Image Credit: Scott Lewis)     Engineers at the Auto-ID Lab at MIT have develop ...
With the shutdown of 2G and 3G networks looming on the horizon, many organizations are faced with the difficult question of “So, what’s next?” The key question to really ask is, “Well, what is the application?” Meaning, what is the current or projected use case and how will it be impacted by the new LTE technology. In addition, ask yourself where are you today and where do you want to be in five years; and most importantly, what business problems are you trying to s ...
Right on the edge of an interconnectedness world, where the life of millions of people around the globe changes daily because of the advances in technology, the evolution of mobile communications will revolutionize our world and benefit entire economies and societies —even more than electricity, rail systems, or the automobile.   While the first-generation of mobile communications, or 1G (GSM), only allowed analog voice phone calls and the second-generation, 2G (GPRS and EDGE) introd ...

The NRF24L01+ is a popular wireless transceiver which is used in many common devices such as key ...
  Since we launched Smart Power Strip last week, many of my friends working in wireless domain asked me the benefits and reason behind selection of Wi-Fi standard over zigbee, 2.4GHz   and other wireless options for our home automation product line. Well, this post is to answer that. In mid-late 2014 when we decided to build Anytime Anywhere control of home/office devices we were also struggling between various wireless standards. However, when we did couple of white boarding sess ...
Wireless Communications Continuing yesterday's glance forward into the future of FPGA, today I'd like to hear your thoughts on what's coming next for wireless communications. Now, as you guys know, this is a pretty broad subject, but I'm not really looking to reign it in to any great degree. It's one of the foundation levels for so much of the current tech that wireless communications is something that electronics people from across the board give a lot of thought over to, as it can be the lin ...

RFBee Troubleshooting

Posted by tombates6 May 12, 2015
Hi,      I have recently been trying to get started on a wireless project using two RFBees I bought years ago... And now I understand why I gave up the first time. All of the information on how to do anything, including uploading the firmware, is completely outdated. I cannot do a single thing with my RFBees because I uploaded a sketch of my own. It shouldn't be this hard to just communicate wirelessly, should it? Can someone please help me at least find a reliable guide on ...
McDonalds got to where it is (36,000 local restaurants serving 69 million people in more than 100 countries) by meeting its customer definition of value and by ensuring that there is not a long wait between the time you order and the time you bite into a Quarter Pounder (the “‘fast” in fast food). But can the same be said for its WiFi service? The value proposition is a no-brainer from a cost perpective since Mickey D’s offers free WiFi at its restaurants around the world ...
Device Discovery has evolved over the years and become a key mechanism by which infrastructures and their clients have become easier to setup. A number of device discovery protocols now exist including the commonly known mDNS and NetBIOS protocols.   The primary purpose of techniques such as mDNS is to quickly and easily resolve host names to IP addresses within small networks that don’t necessarily include local Domain Name Servers (DNS) such as the typical home network. The techni ...
ACKme BLE modules control peripheral devices via GPIOs (General Purpose Input Output devices). GPIO commands and variables enable access to GPIOs, to control and monitor analog functions such as analog-digital converters (ADCs) and PWMs (Pulse Width Modulators). In the case of the ACKme Wahoo evaluation board, peripherals include the tri-color LED, the speaker, user buttons and the thermistor ADC. Features Demonstrated GPIO commands and variables: get gp u - List GPIO usage, direction and initia ...
TruConnect, an easy to use front end API and provides a wireless link between your device(s) and/or a PC or mobile device. This application note demonstrates using a Bobcat module as a wireless serial port, streaming data in and out via the BLE wireless interface. The demonstration uses two Wahoo evaluation boards. Features Demonstrated Serial Interface Stream Mode Advertising to other Bluetooth devices (adv command) Scanning for other Bluetooth devices (scan command) Connecting to another B ...
Its the season of giving and we've added two of the most requested features from the Sensors.com technology suite and added them to the free goHACKme cloud service.   We added the ability for you to send PUSH notifications straight to your computer and/or your phone. Simply put, if you trigger an event on your ACKme hardware, you can easily receive a notification on your phone or computer                             & ...
