The Market for Bluetooth 5.1 SoCs Heats Up as Goodix Enters the Arena
How does the new transceiver hold up against forerunners from Nordic Semiconductor and Dialog Semiconductor? Back in 2017, AAC contributor Tim Youngblood debriefed us on the then-current state of SoCs for Bluetooth 5. But now, with updated Bluetooth protocols and more demanding IoT devices, we’d like to revisit the topic with a fresh look at Bluetooth 5.1 SoCs gaining traction.

Uncover SweynTooth vulnerabilities with Defensics fuzz testing
SweynTooth is a set of Bluetooth Low Energy vulnerabilities. We can reproduce many of these vulnerabilities using Defensics Bluetooth LE Test Suites. What is SweynTooth? SweynTooth is a set of Bluetooth Low Energy vulnerabilities discovered and disclosed by Singapore University of Technology and Design researchers. These vulnerabilities were found in various Bluetooth LE software development kits from seven system-on-chip vendors.

Qualcomm unveils the true-wireless earbud chips to battle AirPods Pro
Qualcomm has revealed its next-generation audio SoCs for truly wireless earbuds, and if you’ve been considering a set of AirPods Pro or similar, you may want to wait until later in the year. The Qualcomm QCC514x and QCC304x Bluetooth chipsets for earbuds promise features like integrated active noise cancelation, lower power requirements, and support for voice assistants like Alexa and the Google Assistant.

iOS 14 code hints BMW could be first to use Apple’s ‘CarKey’ API, report says
Without going into detail, 9to5Mac reports “evidence” in a pre-release version of the as-yet-unannounced iOS 14 indicates BMW will be the first automaker to support “CarKey” if and when the initiative launches. When reached for comment, BMW was unable to confirm its role in Apple’s plans. The German carmaker pointed to a December press release outlining its commitment to a global Digital Key standard.

Translating a surveillance tool into a virus tag for democracy
Oxford researchers modeled the use of phone tracking and alarms to spread the coronavirus, saying that such a system could be helpful even if it was not generally deployed and location information was not always accurate. Most, but not all, people in the area should use it. In fact, it could immediately repeat a week’s worth of contact tracing, the researchers said.

Bluetooth LE asset condition monitoring solution enables prediction of mounted-bearing maintenance
Nordic Semiconductor today announces that its nRF52832 Bluetooth® Low Energy (Bluetooth LE) System-on-Chip (SoC) is successfully providing wireless connectivity for the ‘ABB Ability™ Smart Sensor’ for mechanical products, ABB’s solution for remote asset monitoring. 

Tracking Dismounted Soldiers without GPS
The Four Seasons Hotel One Dalton Street, Boston implemented custom-designed VingCard Essence door locks alongside VingCard Signature radio frequency ID locks from Assa Abloy Global Solutions. A newly opened and modern 61-story skyscraper that serves as both a hotel and residential building, the hotel sought both Assa Abloy Global Solutions and Assa Abloy Opening Solutions Americas to implement a customized state-of-the-art security access system that would match the building’s exterior design and style.
