No Blues with Bluetooth! GATT Explained - Part 5 - Understanding Higher Protocol Layers Provides Interoperability Help

After exploring low-level layers of Bluetooth Low Energy in previous editions, and establishing connections in Part 4, Robert examines Attribute Protocol and Generic Attribute Profile or GATT in Part 5. These higher layer protocols provide developers with greater opportunity for interoperability with third-party applications or products.

Power Analysis Over JTAG Ports: Hidden Debug Dangers - Block Side-Channel Analysis Attacks

Small changes in the phase of clock signals can encode power leakages. An attacker can use standard interfaces such as the JTAG port to drive clocks across targets, using them as measurement techniques for sidechannel analysis attacks despite limited physical access. This article demonstrates how you can test devices for vulnerability and how to modify devices to prevent attacks.

Mobile APP Development with React Native

This month, Bob continues his series on mobile app development from an embedded designer's perspective. He programs a React Native app and he offers guidelines for picking a tutorial for React Native. He further explores how it handles concurrency and asynchronous programming. Bob expected a few nuances during the process but to say there were more than a few would be an understatement.

The Blues Wireless Notecard-LoRa

After having built a number of Wi-Fi IoT gadgets for the home, Brian became curious to see how LoRaWAN-based IoT devices would work. He decided to investigate the Notecard LoRa IoT modules made by Blues Wireless.

Bringing Cost-Effective, On-Device AI to Home Appliances - Sparse Weights and Interactions Negate GPUs and Cloud Computing

GPU silicon and cloud computing infrastructure are too costly for mass markets devices like refrigerators and washers. By deploying compute resources only to the necessary parts of AI inference, Sparse AI allows product designers to practically incorporate new AI features like natural voice interfaces into their consumer offerings without breaking the bank or electric bill surprises.

Exploring Infrasound - Tornado Early Warning Detection Project Using Raspberry Pi Pico and a Python Supervisory Program

Inspired by the possibility of building an early warning system for tornadoes, Dev developed an infrasound detector. Tornadoes are rare in his area, but his detector found other infrasound activity using sensor circuitry based on a Raspberry Pi Pico, combined with a Python supervisory program that stores data on a computer for analysis.

Healthy Protein Can Help Shrink Your Gut - Being a trainer, bodybuilder, and nutrition expert means that companies frequently send me their products and ask for my stamp of approval.

Like my father always said, "What you put inside your body always shows up on the outside." One protein shake that I received, that will remain nameless, was touted as 'the next big shake' but really had a list of gut destroying ingredients. Everywhere I read I saw harmful artificial ingredients, added sugars, synthetic dyes, preservatives and cheap proteins; the kind of proteins that keep you fat no matter how hard you hit the gym, sap your energy and do nothing for your muscles.

What's Ailing Our Doctors? - Today's physicians are burned out and battered by spreadsheets. We patients suffer too.

Today’s physicians are burned out and battered by spreadsheets. We patients suffer too. America's doctors are in crisis. Six in 10 physicians say they're burned out, with burnout rates for some specialties, such as primary care, reaching 70%. When polled by the American Medical Association, 40% of doctors said they were considering leaving their practices in the next two years. Another study, conducted by health-care industry publisher Elsevier, revealed concerns about mental health and burnout: 63% of med students in the United States reported that they had no intention of practicing clinical medicine after graduation and will instead work as lab researchers or academics. This is despite a predicted shortage of 124,000 physicians over the next 10 years.
