What I'm Working On

I'm running Bluetooth LE Unplugged, a hands-on course that teaches the Bluetooth LE protocol through real hardware and AT commands, no firmware toolchain or SDK required. Two BleuIO USB dongles ship to your door, and Module 8 walks through all four pairing association models (Just Works, Numeric Comparison, Passkey Entry, OOB) with sniffer captures of the actual SMP exchanges.

Ceva announces a Bluetooth HDT design win with integrated RF

PR Newswire

Ceva announced a major customer win for its Bluetooth High Data Throughput (HDT) solution including its internally developed RF technology. The customer, a leading U.S.-based semiconductor company, had previously licensed Ceva's Bluetooth IP portfolio and has now adopted Ceva's Bluetooth HDT platform, combining digital baseband, software stack and Ceva's internally developed RF technology. Bluetooth 6.0 designs are entering production at multiple customers, with royalties beginning to ramp, while early Bluetooth HDT design wins position Ceva at the center of the next wave of high-performance wireless devices.

Moto Tag 2 launches with UWB, Bluetooth 6.0 and Channel Sounding

Gizmochina

Motorola has quietly launched the new Moto Tag 2 in parts of Europe. It's a compact tracker designed for attaching to things like keys, bags, wallets, or luggage, and it connects through Google's Find Hub network on Android devices. The Moto Tag 2 supports Ultra-Wideband (UWB) alongside Bluetooth 6.0 and Bluetooth Channel Sounding, which allows for much more accurate nearby positioning compared to regular Bluetooth trackers.

Clawdmeter: a DIY ESP32-S3 desk dashboard for Claude Code token usage monitoring

CNX-Software

Clawdmeter is a DIY ESP32-S3-powered desk dashboard that displays Claude Code token usage on a 2.16-inch AMOLED screen so you know when you're about to reach the limits in real time. It's mostly a firmware project since it relies on off-the-shelf hardware (Waveshare ESP32-S3-Touch-AMOLED-2.16). It leverages the LVGL library for its graphics user interface, the NimBLE stack for Bluetooth LE communication, and also functions as a HID keyboard for shortcuts using the buttons from the unit.

Auracast broadcast audio transforms the home theater experience

Bluetooth SIG Blog

Since its launch, Auracast broadcast audio has been deployed and proven across a diverse range of settings, including theaters, music venues, and conference halls. Solutions in these spaces enhance engagement and accessibility through multichannel broadcasting, high-fidelity audio, and narration services. By including Auracast broadcast audio in home theater solutions, Hisense has addressed the pain points of traditional approaches, supporting an open-standard wireless home surround sound system that delivers an entirely new audio experience for users.

Sick launches Coriva, a UWB-based RTLS for factories

Drives & Controls

The German sensor-maker Sick has announced a real-time localisation system (RTLS) that determines the exact position of industrial assets such as vehicles, workpieces and materials in a factory, thus giving visibility, security and traceability to operators. Based on an ultra-wideband (UWB) technology, Coriva has been designed to localise, track and manage assets in real-time. The system comprises mobile UWB tags (CorivaTags), a permanently installed infrastructure (CorivaSat) and software (CorivaEngine), which calculates the positions of the mobile assets.

Beyond Bluetooth and UWB: how Low-Energy UWB is redefining presence and proximity sensing

RFID Journal

In today's rapidly expanding Internet of Things (IoT) landscape, presence detection and ranging technologies are becoming the backbone of intelligent spaces from hospitals and construction sites to industrial floors and smart vehicles. Yet most of today's connected devices are still limited by legacy short-range wireless technologies that weren't designed for low-power, high-responsiveness sensing. Bluetooth LE and conventional ultra-wideband (UWB) technologies have served well in presence and proximity detection applications. As the demand for real-time, energy-efficient and interference-resilient systems accelerates, a new approach is needed.
