Bluetera II is a motion-enabled IoT development board that supports protocol buffers (Crowdfunding)

Tensor Iotera Group (TIG), an Israeli based technology company, has launched a powerful IoT development board featuring motion sensing called Bluetera II and supporting Google Protocol buffers. Bluetera II came from the idea that developing an IoT application shouldn’t be complicated. Hardware is hard, and scaling for manufacturing might also be more daunting than initially anticipated. So instead of going through those troubles, why don’t you go the route of something that works, and most importantly, is scalable, as TIG is advocating with their Bluetera IoT development platform. Bluetera II is the 2nd generation of this IoT platform. The Bluetera II board is equipped with a 9-axis motion sensor, Bluetooth 5 enabled Nordic nRF52840 SoC core, which features an Arm Cortex-M4 FPU, with 1MB of Flash, 256KB of RAM, and lastly, an SDK based on Google’s Protocol Buffer (protobuf) technology. The device can function as a BLE Central (Master) and […]

VOIXATCH Smartwatch Comes with a Detachable Bluetooth Headset (Crowdfunding)

As a Kickstarter project, VOIXATCH introduces the world’s first smartwatch device which puts essential features of all the devices we carry with us in one unit. This watch does everything that smartwatches do, plus it has a built-in Bluetooth headset. Other smartwatches can be used with Bluetooth headset, but VOIXATCH has a Bluetooth ring-look-like headset docked on it, and the headset can be detached anytime and used for phone calls or listening to the music. One can call it a headset smartwatch. Cool, huh? After Mobile World Congress 2019, where Voixatch demonstrated the watch, it is finally available for “purchase” on Kickstarter rewards starting at $179 and first batch delivery expected in June. VOIXATCH embodies LTE, GPS connectivity in an all-in-one truly wireless design that can be used with Google Voice. The watch can also be used as a cellular smartwatch with a bezel headset to make calls and stay […]

V-Powerbuds Pro TWS Earbuds Support Heart Monitoring & Oxygen Tracking (Crowdfunding)

Vimai V-Powerbuds Pro Multi-function Sport Earbuds Vimai’s V-Powerbuds Pro TWS (True Wireless Stereo) earbuds are multi-function wireless earbuds. In the past, we had reported on the Misfit Specter Bluetooth earbuds that could track fitness input, such as steps, calories, and sleep duration. V-Powerbuds Pro also tracks heart rate, oxygen, and respiration, and supports online & offline voice control. The Component Basics The V-Powerbud Pro are TWS earbuds and have a built-in pulse oximeter to capture heart rate and oxygen levels right from within the ear. The hook design holds the earbuds tightly in place, within the ear, to get an accurate measurement independent of the effects of light. Other types of fitness tracking devices like those located on the wrist, can be affected by light. The Difference From Other Sport Earbuds Although the uses during exercise aspect of this wearable are probably more likely to be a selling point, the […]

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

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 […]

Bluetooth LE Audio Supports LC3 Codec, Multi-stream & Broadcast Audio, Nordic Semi Evaluation Kit Unveiled

I first heard about Bluetooth LE (Low Energy)- part of Bluetooth 4.0- in 2013 with RFDuino board, and it came to prominence once Android 4.3 added support later this year. Bluetooth LE is using to transmit messages using as little as energy as possible for example to synchronize data between a smartphone and a smartwatch. But if you ever had to transmit audio, you had to rely on Bluetooth Classic which, albeit considering low power, consumes more energy. But you should soon have much longer battery life on your Bluetooth headphone or battery-operated speaker, as the Bluetooth SIG has just announced Bluetooth LE Audio which adds a new codec and support for multi-stream and broadcast audio. The new high-quality, low-power audio codec used in the new Bluetooth standard is called the Low Complexity Communications Codec (LC3). The chart above shows the results of listening tests between LC3 and SBC codecs […]
