Hospitals Facing Covid-19 Can Track Equipment Via Data Automation
During the ongoing Covid-19 crisis, tracking medical equipment in healthcare facilities is a critical, but complicated challenge. Or else, it used to be, according to a recent release from Nordic Semiconductor. The company recently unveiled a Bluetooth Low Energy (LE) AC plug-in wireless hub and room-level ‘stick-on’ beacon asset tracking solution, which was developed by Sixgill, that employs Nordic’s nRF52832 Systems-on-Chip (SoCs).

Bluetooth direction finding brings a new dimension to indoor asset tracking
Since opening the Global Positioning System (GPS) for civilian use in the 1980s, GPS technology has become a mainstream and de facto solution for outdoor positioning and asset tracking, finding its way first from commercial airplanes to smartphones and smartwatches to match-box-sized GPS trackers. 

New NHS coronavirus tracking app plagued with major technical issues
A new mobile app launched by the government as part of its ‘track, trace, and test’ programme to slow the spread of the coronavirus has had major technical issues, an analysis has found. UK privacy charity Privacy International has claimed the NHSX app, built to track and trace people who have had Covid-19, does not work if left on in the background or if the phone is put to sleep.

Finding Your Lost Laptop Will Soon Become Easier Than Ever
If you’re worried about losing your laptop someday, then rest assured. Intel has partnered with the smart location company Tile to bring a dedicated laptop tracking tech in the market. Tile is already is known for its Bluetooth-powered tracking tags that can be tied to various objects and locate them via its Android or iOS apps. There’s is no need for an internet connection. On top of it, the app also stores the GPS coordinates of the location when it had the last contact with the tracker tag.

Renesas Extends Bluetooth 5.0 Connectivity to RA Family of 32-Bit MCUs with Arm Cortex-M Core
Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, today introduced the first RA microcontroller (MCU) with an integrated Bluetooth ® 5.0 Low Energy radio. The single-chip RA4W1 MCU includes a 48 MHz, 32-bit Arm® Cortex®-M4 core and Bluetooth 5.0 core delivered in a 56-pin QFN package. Together, the RA4W1 MCU and easy-to-use Flexible Software Package (FSP) enables engineers to immediately begin development with Arm ecosystem software and hardware building blocks that work out-of-the-box with RA MCUs.

COVIDSafe app data yet to be used, Bluetooth fix reliant on Apple, Google
More than five million Australians have downloaded the COVIDSafe app, but it doesn’t work properly on a lot of phones, and isn’t actually sharing any data with health authorities yet. In a Senate Select Committee hearing on Wednesday, Randall Brugeaud, head of the Government’s Digital Transformation Agency, confirmed the app doesn’t work properly for iPhone users, and that it will be augmented with a system being developed by Apple and Google when it becomes available.

NXP Releases Two More MCUs for IoT Devices
