U-blox has created an omlox-compatible indoor asset tracking system based on Bluetooth LE Angle-of-Arrival technology. Branded ‘u-locate’, “it offers every necessary hardware, software and middleware component for indoor positioning, including support for interoperability with the omlox standard”, according to u-blox. “Based on Bluetooth LE AoA, u-locate delivers positioning accuracy down to 10cm while ensuring extended tag battery life.” Omlox, owned ...

Ceva has introduced a multi-radio intellectual property package for IoT IC designers that combines Wi-Fi 6, Bluetooth 5.4 and 802.15.4 modems with a 2.4GHz transceiver aimed at TSMC’s 22nm process. Called Links100 (diagram right), it is the first of a series of IP products (diagram below) that will also include transceivers for Wi-Fi 7 with MLO (multi-link operation), and UWB ...

Silicon Labs has announced an Arm Cortex-M33 based family of secured wireless microcontrollers covering Matter, OpenThread, Zigbee and Bluetooth LE. Called xG26, it consists of MG26 devices for Matter, OpenThread and Zigbee, BG26 devices for Bluetooth LE and Bluetooth Mesh, and PG26 devices for the same processing power without wireless transceivers. “As users from consumer to industrial sectors extract more ...

Alif Semiconductor has put an Arm Ethos-U55 neural processor alongside a Bluetooth Low Energy radio in a microcontroller for AI and machine learning workloads – all in a tine WLCSP package. It is called Balletto. “Balletto gives manufacturers the opportunity to implement AI/ML functions such as speech recognition, adaptive noise cancellation, vocal targeting and beam forming in true wireless stereo ...

NXP has finally revealed the wireless versions of its MCX microcontrollers, first announced in mid-2022. “Featuring the industry’s first MCU with Bluetooth Channel Sounding, NXP’s MCX W series enables edge devices with secure multi-protocol wireless for Matter, Thread, Zigbee and Bluetooth Low Energy,” according to the company, which explained: “Bluetooth Channel Sounding standard improves the accuracy and security of distance ...

u-blox has announced four stamp-sized wireless MCU modules that can run user code and support Bluetooth LE 5.4, Thread, Matter and PSA Certified Level 3 security. ALMA-B10x versions are built around Nordic Semiconductor’s nRF54H20 wireless microcontrollers and have dual 320MHz Arm Cortex-M33 cores, dual 320MHz RISC-V cores, plus 2Mbyte of non-volatile memory and 1Mbyte ram. They also support NFC-A. NORA-B20x ...

There's a new Arduino board in town - the Nano 33 BLE Rev2, a new iteration of Arduino's popular board that features built-in magnetometer and inertial measurements, and Bluetooth LE.

Arduino has bought out second revisions of its Nano 33 BLE and Nano 33 BLE Sense bluetooth-equipped microcontroller boards, keeping the sensor mix, but changing several of the sensor ICs. The nRF52840 IC (via a u-blox NINA-B306 module) stays the same, and still provides both an Arm Cortex-M4 processor and a Bluetooth transceiver – to go with these is an ...

Zhejiang University and Microaiot have created a passive crystal-less tag IC that both receives its instructions and is powered by Wi-Fi, and sends its responses over Bluetooth. They described the device at ISSCC in San Francisco this week. The tag has two antennas, with both used to extract power from the incident Wi-Fi field. One also receives the Wi-Fi (802.11b) ...

Infineon has introduced a ~10 x 20mm antenna-inclusive Bluetooth 5.0 (core spec) module that consumes 1.3mA receiving (-95dBm) and 3mA transmitting (0dBm). Called CYW20822-P4TAI040, it sleeps at 2μA when retaining 32kbyte of ram, or hibernates at 800nA – the latter rising to 950nA hibernating with the wake-up receiver enabled. At maximum transmit power (+4dBm) up to 250m of range can be ...
