Bluetooth LE

EE Times
It wasn’t until November 2025 that the Bluetooth Special Interest Group (Bluetooth SIG) officially released Bluetooth Core 6.2, marking the debut of the SCI (Shorter Connection Intervals) feature. ULL SCI is a major upgrade to Bluetooth ULL technology. Its core lies in optimizing the timing parameters of Bluetooth LE ACL (Asynchronous Connection-Oriented), reducing the traditional minimum connection interval of 7.5ms to 375μs, thereby significantly increasing the frequency of data exchange.

VOXMICRO today released the AIRETOS C27 Class, an industrial Wi-Fi 7 and Bluetooth 6.0 wireless module powered by the Qualcomm FastConnect C7700 Connectivity System. The AIRETOS C27 is built on the Qualcomm FastConnect C7700 silicon foundation that supports Bluetooth 6.0 with Bluetooth Channel Sounding and Bluetooth LE Long Range (Coded PHY). Channel Sounding enables sub-meter ranging between Bluetooth-enabled devices, and Bluetooth LE Long Range extends connectivity across distances that previously required a dedicated long-range radio.

The Qualcomm QCC74xM EVK is a tri-radio evaluation board with Wi-Fi 6, Bluetooth 5.4, and IEEE 802.15.4 (Thread/Zigbee) with a price tag of just over $13. The official development boards for the QCC74x series have finally been released. What is interesting is that, while it carries the Qualcomm brand, documentation from the Zephyr Project clearly shows that the QCC74x series is actually based on and mostly equivalent to the Bouffalo Lab BL61x series, specifically the BL618.

Anthropic has opened its Claude Hardware Interface (Bluetooth API) to developers, enabling an ESP32-S3-based desk companion to connect directly to the Claude desktop app over Bluetooth Low Energy. To demonstrate this new feature, the company released an open-source reference project called Claude Desktop Buddy. It currently runs on the M5StickC Plus (an ESP32-based board from M5Stack, about $30 on AliExpress and Amazon) and works as a small interactive hardware companion for Claude.

Auracast is a Bluetooth LE Audio broadcast standard that allows a single audio source to stream simultaneously to an unlimited number of compatible devices, including hearing aids, earbuds, headphones, smartphones, and televisions. When the Bluetooth SIG first showcased Auracast, the vision centered around airports, theaters, stadiums, and other large public venues. However, it also unintentionally created the perception that Auracast requires massive infrastructure projects, years of planning, and significant capital investment. The technology is modular, scalable, and compatible with existing sound systems.

Ultra-Wideband (UWB)

Qorvo / NewsWireToday
Qorvo today announced a major step forward in making Ultra-Wideband (UWB) real-time location systems (RTLS) deployable at enterprise scale. By combining industry standards including FiRa and Omlox with integration into Wi-Fi enterprise access points (EAPs), Qorvo enables precise, real-time location services without the need for dedicated RTLS infrastructure. At the core of this ecosystem is Qorvo’s new QPK3000 module, designed for tags and end devices.

How-To Geek
Bluetooth trackers are useful, but for situations where you need precise location tracking, Ultra Wideband (UWB) comes to the rescue. It’s a technology found in AirTags and some other trackers that greatly improves tracking precision, but there’s a catch. If you’re on Android, chances are your phone doesn’t support UWB in the first place, and even if it does, you’re limited to just a few UWB trackers.

P.S. The new Bluetooth Core 6.2 SCI feature pushes connection intervals down to 375μs, which is exactly the kind of tuning lever this week’s sponsored course works with. If you’ve started measuring throughput on real hardware, reply and tell me what bottleneck you ran into first. I’d love to hear it.
