Silicon Labs BG22 Secure Bluetooth 5.2 SoC Promises 10-Year Coin-Cell Battery Life

Silicon Labs BG22 Bluetooth 5.2 SoC

Yesterday, we wrote about the new Bluetooth LE Audio standard which promises smaller Bluetooth audio devices, or longer battery life, as well as support for multi-stream and broadcast audio. But there has been some other Bluetooth developments with the release of Bluetooth 5.2 specification on December 31st, and the announcement of the first Bluetooth 5.2 SoC courtesy of Silicon Labs. Bluetooth 5.2 Main Changes Bluetooth 5.2 builds upon Bluetooth 5.1 with the following key changes: Enhanced Attribute Protocol (EATT) – Improved version of the Attribute Protocol (ATT), which supports concurrent transactions, allows the interleaving of L2CAP packets relating to ATT packets from different applications and allows the ATT Maximum Transmission Unit (MTU) to be changed during a connection. This can reduce latency and improves the responsiveness of Bluetooth LE applications. LE Power Control – Devices can dynamically optimize the transmission power used in communication between connected devices with BLE receivers now able to monitor signal strength and request transmission power-level …

Energous Launches WattUp Smart Glasses Developer Kit for Customer Product Designs

The WattUp Smart Glasses Developer Kit

Near-field wireless charging technology has the potential to disrupt the consumer electronics industry, but its adoption has been limited. Energous wireless charging technology WattUp has promised to change that narrative by making it possible to charge devices mid-field (on the desk) or far off (in the room. Aside from the distance challenge in wireless charging, one other major issue is the fact that there are few deployments with them. Only a few devices have wireless charging incorporated. Energous is hoping to change that as well with the launch of the WattUp Smart Glasses Developer Kit, which is tailored for custom product design in the wearable industry. Energous is continuing its trend of launching a developer kit after having released the WattUp Hearables Developer Kit with Near-Field Wireless Charging and support for the SKIIN Smart Underwears. According to the Energous, the goal of the smart glasses developer kit is: Designed to ease manufacturers’ integration of WattUp into smart glasses, the new …

ProteusDevice Secure, Open-Source Linux Handheld Features Ethernet Connectivity

ProteusDevice XXLSEC Ltd., the developer of the Privecall-TX device, has developed a near-identical, slightly bigger ProteusDevice, which runs the Linux 5.4 based PriveOS. The ProteusDevice handheld device (“not a mobile phone”) is said to have very tight security and was developed with secure access in mind. Background and Linux Handheld Market The market is seeing more Linux handheld and phones such as the Purism Librem 5, the PinePhone “Braveheart”  both of which are already in mass production. There are also other computing options with the handheld Pocket Popcorn Computer, which is much like the PocketChip, but decidedly improved and faster in general, as well as the Solectrix SX Mobile Device Kit which is more of a business option, for smartphone, opensource development with no cellular connectivity, but Gigabit Ethernet and USB-to-UART ports. Some Features and Mystery Production The ProteusDevice is in good company, and has a solid start, but is still a bit of a mystery, as to price and …

Google ADT-3 is a Developer-Focused TV Box for Android TV on Android 10

Google ADT-3 Android TV 10 Developer-Kit

Back in 2014, Google killed Google TV and announced Android TV, and as a result, introduced ADT-1, the first developer kit specifically designed for Android TV.  Since then ADT-2 was introduced in 2018 in an HDMI stick form factor, and now the company has announced the launch of Android TV on Android 10 together with ADT-3 devkit targetting Android TV app development for Android 10. The “developer kit” just looks like a standard TV box, although It’s really tiny and comes with what looks like a voice remote control. Google did not provide the full specifications, but ADT-3 is equipped with a quad-core Cortex A53 processor coupled with 2GB DDR3 memory, and supports 4Kp60 HDR video playback and output via an HDMI 2.1 output port. That probably means the box is powered by an Amlogic S905X2 processor since few other TV box SoCs combine 4x A53 cores with HDMI 2.1. The device is pre-certified, and will receive updates and security …

Semtech SX1302 LoRa Transceiver to Deliver Cheaper, More Efficient Gateways

SX1302 Raspberry Pi Gateway

After our interview with Rak Wireless CEO, we received a comment inquiring about the availability of SX1302 gateways. Semtech so far had two LoRa transceivers for gateways namely SX1301 and SX1308, but I had never heard about a third one. Semtech SX1302 is brand new, the latest generation of baseband LoRa chip for gateways that is said to reduce current consumption in order to simplify the thermal design of gateways, as well as the BoM (bill of materials) costs), while being capable of handling a higher amount of traffic. Semtech SX1302 LoRa Transceiver Key features: Up to -141 dBm sensitivity with SX1250 Tx/Rx front-end 125 kHz LoRa reception with: 8 x 8 channels LoRa packet detectors 8 x SF5-SF12 LoRa demodulators 8 x SF5-SF10 LoRa demodulators 125 /250 / 500 kHz LoRa demodulator (G)FSK demodulator Direct interface to Semtech transceivers SX1255, SX1257 and SX1250 SPI host interface Single 32 MHz clock QFN68 Package Temperature Range – -40°C to +85°C.

Atomic Pi x86 SBC Meets Intel Neural Compute Stick 2 in $99 Neural Computing DevKit (Crowdfunding)

Atomic Pi Neural Computing Development Kit

IoT Team launched the $34 Atomic Pi SBC powered by an Intel Atom x5-Z8350 processor via a Kickstarter campaign last December. At the time, it only ships to the US, and looked too good to be true. But the thing is real coming from a failed robotics project, and the low-cost x86 board went back for sale via Amazon and other channels with worldwide availability last spring. The price has even gone a bit lower as you’ll find it for $32.95 on Amazon. Note that it requires some technical skills to get started and with 16GB eMMC flash it only supports Liux distributions such as Ubuntu 18.04, and installing Windows 10 is possible, but you’ll be seriously limited. Atomic Pi is back in the news, as IoT Team has now launched another Kickstarter campaign for the board, except it’s not sold standalone, but instead as part of a $99 neural computing development kit that combines Atomic Pi SBC with 2GB …
