Arduino Partners with Chirp to Enable Data-Over-Sound M2M Connectivity

Announced on August 12, 2019, Arduino has partnered with the London-based Chirp, a wireless data-over-sound software solution for machine-to-machine connectivity.  The system has the ability to work online or offline, as long as there is a loudspeaker and a microphone available. The software works with the Arduino Nano 33 BLE Sense board in send and receive mode, while most Arduino MKR boards and Arduino Nano 33 IoT will also be supported by the SDK, but only to send data. The software and board are fully compatible with SDKs from a wide variety of platforms. The Nano 33 BLE Sense is available for purchase from the Arduino website, for $29.50. The sensor-rich Arduino Nano 33 BLE Sense is application-ready right out of the box, and Chirp is ready to start sending encoded data from a device fitted with an audio speaker, to the board’s built-in microphone, where it is encoded and delivered. The sound is above the hearing range of human’s, …

Icarus IoT Board Features nRF9160 GPS + NB-IoT SiP in Adafruit Feather Form Factor

The new Icarus IoT board from Actinius, uses the Nordic nRF9160 SiP, a powerful yet low power system in a package designed for use with GPS and LTE-M & NB-IoT cellular data, also found in Ruuvi node which we covered a few months ago. The board’s purpose is for mobility and ease of project tracking anywhere, and can be found in application scenarios such as fleet management and security, cargo tracking, or asset monitoring, and many more. The board has power inputs for solar panel, USB or LiPo/Li-Ion Battery, which widens the boards mobile nature, and on-site, in-the-field capability. Since the form factor follows Adafruit Feather, the Icarus board benefits of additional component options for prototyping and DIY electronics projects. The nRF9160, by Nordic Semiconductor, is a SiP (System in a Package) that carries an extensive line of embedded software and hardware. As we had reported the nRF9160 SiP low-power IoT solution consists of a global multimode LTE-M/NB IoT modem, …

Aconno Bluetooth Beacons Come with Various Sensors, Nordic Semi nRF52 BLE SoC

Aconno Bluetooth Beacons

We first covered products from Aconno is 2017 with their Bluetooth LE development board powered by the company’s ACN52832 BLE module based on Nordic Semi nRF52832 ARM Cortex-M4 multi-procotol wireless SoC. Since then they’ve launched several small Bluetooth beacon modules based on ACN52832, and the company has what they call a presale promotion until May 21st, but it looks really like a group buying event for their existing BLE modules where the price goes down as more people purchase modules. Six Bluetooth modules are offered: acnSENSA multisensor Bluetooth tag with temperature, light, humidity, barometer, accelerometer, magnetometer, gyroscope acnBEACON programmable Bluetooth tag acnACT BLE beacon with button and RGD LED, magnetometer, phototransistor acnNFC programmable Bluetooth tag with NFC tag emulator acnRANGE distance measuring beacon with time-of-flight sensor acnFIND Bluetooth smart tag with LED, sound and accelerometer All modules come with a replaceable CR2450 battery, and IP65 enclosure. Pricing currently ranges from 15.96 Euros (Net) to 29.40 Euros (Net), but price may …

Ruuvi Node Open-source Node Solution Combines Nordic Semi nRF9160 Cellular SiP & nRF52840 Bluetooth SoC

Ruuvi Node NB-IoT Bluetooth 5 Solution

Back in 2016, we covered Ruuvi Innovations’ Ruuvitag open source Bluetooth & NFC sensor beacon is based on Nordic Semi nRF52832 Bluetooth SoC. The company has now introduced Ruuvi node, another open source multi-purpose, industrial-grade cellular gateway, environmental sensing, and asset tracking node solution based on not one, but two Nordic Semi chips with nRF91 cellular IoT SiP (System-in-Package) with NB-IoT and LTE M (eMTC) connectivity and nRF52840 multi-protocol Bluetooth 5.0 SoC. It’s an early announcement with the launch of the first pilots of Ruuvi Node planned for Q2/Q3 of this year, so the full specifications are yet to be released. However, thanks to a press release on Nordic Semi website, we do know that Ruuvi Node is meant to be maintenance-free, will include a solar panel for  energy harvesting (which mean the included 45Wh battery may never run out depending on the application), several environmental sensors, GPS positioning provided via nRF9160 SiP, and NFC for securely reading device IDs …

Obvious is an App Store for Embedded Devices

Obvious app store embedded devices

Mobile devices have gotten their own app stores for more than 10 years already, with Google Play for Android and Apple App Store for iPhones and iPads. Linux powered IoT devices – usually gateways – also got their own app stores with branded Ubuntu app stores relying on Ubuntu Snaps,  although I’m not sure they are widely used. However, low power embedded devices usually based on microcontrollers did not get their own app store, and Obvious aims to fill this gap with the Obvious platform, an app store for embedded devices, which enabled after-sales features and upgrades. Obvious app store is currently in Beta and works exclusively with Nordic Semi based products at this stage. We don’t know an awful lot about the services, except it will enable a new revenue stream for providers of low power wireless IoT devices. Some benefits listed by the company include: Untapped resources –  Spare CPU cycles, an extra I/O port or an unused …
