Breaking BLE — Vulnerabilities in pairing protocols leave Bluetooth devices open for attack
Despite built-in safe-guards, Bluetooth Low Energy IoT devices are vulnerable to hacks when they communicate over the air. Here are the basics of the problem. Leland Teschler, Executive Editor If you eyeball internet-of-things items ranging from smart ac plugs to motion sensors you typically find connectivity via the Bluetooth Low Energy (BLE) standard. A lot […]
Developing connected medical devices for the IoT
Super-small radio SoCs are being paired with innovative battery technologies to bring inexpensive medical electronics online. Adrie Van Meijeren, Low Power Connectivity • Dialog Semiconductor The Internet of Things (IoT) has disrupted many industries in short order. However, when it comes to adopting the IoT, the medical and pharmaceutical space has largely been held back. […]
How to test USB4 designs
Designers must look at and characterize the entire Type-C ecosystem when testing USB4 designs. Jit Lim • Keysight Technologies The USB Type-C connector has received significant adoption with ubiquitous standards like USB, DP, and Thunderbolt. The next-generation variant of USB is USB4. USB4 will transmit and receive on all four lanes of the Type-C connector […]
Selecting the right Bluetooth Low Energy SoC
Tricks of the trade for optimizing the energy consumption of BLE chips affect memory size, clock speed, operating modes, and other factors determined during the initial design. Emmanuel Sambuis, Silicon Labs It can be challenging to optimize Bluetooth Low Energy (BLE) applications for minimal energy consumption. An understanding of BLE and the underlying system-on-chip (SoC) […]
No, IoT RF radiation won’t cause a pandemic
leland teschler | executive editor I once had a lengthy exchange with a guy who claimed RF from WiFi was making him sick. After numerous emails back and forth in which I tried to correct his misconceptions about WiFi signals, I gently suggested that he go find an RF screen room and sit in it […]
First back-biased GMR speed/direction sensor handles air gaps 50% larger

The CCE4503 is a new IO-Link IC that connects the smallest and most price-sensitive IO-Link Device sensors and actuators. The CCE4503 is the first IO-Link IC to be launched by Dialog Semiconductor following its acquisition of Creative Chips in November 2019 and complements the company’s well-established family of IO-Link Device and Master ICs. IO-Link is […]
Budget-priced AI MCU combines machine learning with scalar, floating, fixed-point and vector instructions
A new processor called xcore.ai for the AIoT market delivers high-performance AI, DSP, control and IO in a single device with prices from $1. Traditionally this type of capability would be deployed either through a powerful (and costly) applications processor or a microcontroller with additional components to accelerate key capabilities. However, the new xcore.ai crossover […]
