Samsung Introduces $5 ARTIK 0 and $50 ARTIK 7 Smart IoT Module Families

Samsung unveiled ARTIK 1, 3 and 5 boards for the Internet of Things in 2015, and started to sell them, together with development with WiFi, BLE and Zigbee connectivity earlier this year. The Korean company has now announced two new family with ARTIK 0 modules powered by an ARM Cortex-M MCU and destined to be used in HVAC, lighting, industrial sensors, personal health monitoring and more, as well as ARTIK 7 family powered by an Octa-core Cortex A53 processor, and targeting IoT gateways. ARTIK 0 Family ARTIK 0 family is now comprised for ARTIK 020 with Bluetooth, and ARTIK 030 for applications requiring Thread and/or Zigbee. Beside the different radios, both modules share the same key features: MCU – ARM Cortex-M4 up to 40 MHz with Floating Point Unit, 256KB flash, 32 KB SRAM, advanced hardware cryptographic engine with support for AES-128/-256, ECC, SHA-1, SHA-256, and a Random Number Generator […]

ARM Introduces Secure Cortex-M23 and Cortex-M33 ARMv8-M MCU Cores, and Bluetooth 5 Cordio Radio IP for IoT Applications

ARM TechCon 2016 is now taking place in Santa Clara, California, USA, as ARM has made three announcements for the Internet of Things, the focus of SoftBank going forward, with two ARM Cortex-M ARMv8-M cores integrating ARM TrustZone technology, namely Cortex-M23 low power small footprint core, and Cortex-M33 core with processing power similar to Cortex-M3/M4 cores, as well as Cordio Radio IP for Bluetooth 5 and 802.15.4 connectivity. ARM Cortex-M23 ARM Cortex-M23, based on the ARMv8-M baseline architecture, is the smallest and most energy efficient ARM processor with TrustZone security technology,and targets embedded applications requiring both a small footprint, low power, and security. Its power consumption is low enough to be used in batteryless, energy harvesting IoT nodes, and is roughly a third of Cortex-M33 processor size, and offers more than twice its energy efficiency. Cortex-M23 is a two-stage pipelined processor, software compatible with other processors in the Cortex-M family. […]

Apache Mynewt RTOS for IoT Includes an Open Source Bluetooth 4.2 LE Stack for MCUs

The Apache Software Foundation has recently released version 0.9 Apache Mynewt open source real-time operating systems for micro-controllers under… an Apache 2.0 license. The RTOS works on STMicro STM32 Cortex-M4, and Arduino Zero / M0 Cortex-M0 boards, but they’ve also implemented the first open source Bluetooth Low Energy stack for MCUs, starting with support for Nordic Semi nRF52 Cortex-M4 and nRF51 Cortex-M1 evaluation boards, and acting as a replacement for Nordic SoftDevice Bluetooth Smart / LE solution. The operating system competes with ARM mbed, the Zephyr Project, and RIoT, but the foundation claims it is the only one that’s both community driven and permissively licensed (Apache 2.0) project in the embedded space. The OS is modular and can be configured with a Go-like build and package management tool with components such as secure boot loader, flash file system and TLV storage mechanism, rich logging infrastructure, circular buffering schemes, and Bluetooth […]

OpenThread is an Open Source Implementation of Thread IoT Networking Protocol

Thread was announced about two years ago, as a new IP-based wireless protocol based on 6LoWPAN and 802.15.4 standards and targeting IoT applications. Nest Labs, an Alphabet company, has now released OpenThread open-source implementation of the networking protocol under a BSD license. The source code (C++) for OpenThread includes supports for End Device, Router, Leader & Border Router roles, and can be found on Github. The implementation is said to be OS and platform agnostic with a radio abstraction layer, have a small footprint, and implement all Thread networking layers, namely IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, and Mesh Routing. To quickly get started, you may want to read the Examples README which explains how to build the code, start two nodes, and ping them. Interestingly, while the code is there for everybody to use, only paid members ($2,500 to $100,00) of the Thread group can […]

Embedded Linux Conference 2016 and OpenIoT Summit 2016 Schedule

The Embedded Linux Conference 2016 and the OpenIoT summit 2016 will take place on April 4 – 6, 2016 in San Diego, California, and over 800 attended will meet including kernel & system developers, userspace developers, and product vendors. The Linux Foundation has recently published the schedule, so I’ve had a look at some of the talks, and designed my own virtual schedule to find out more the current development focus although I won’t attend. Monday April 4 10:40am – 11:30am – Linux Connectivity for IoT by Marcel Holtmann, Intel OTC There are many connectivity solutions that available for IoT. For example Bluetooth Low Energy, 802.15.4, Zigbee, OIC, Thread and others.
