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) […]
