Arm Releases Pelion Connectivity Management 2.0 Platform with Greater Automation

Arm has announced its latest version of Pelion IoT Platform, a no-upgrade needed platform Pelion Connectivity Management 2.0 a SaaS with an automation engine.  Previously, we reported on the Sigma Delta Technologies modular devkit that was designed to work with the cloud-based Arm Pelion 1.0 device management service through the Mbed OS, focused on IoT development. The Pelion Connectivity Management 2.0 adds a level of automation that the Pelion 1.0 didn’t have, but that the company felt the customer base in the IoT industry wanted. The new features expand on the Pelion platform, through the Mbed OS, which helped the platform expand through cloud-based management services. The loudest voices in the ever-expanding and transforming IoT industry have said that automation is the key to removing barriers that allow IoT to scale. Pelion 1.0 already offered a single, cloud-based connectivity solution for managing IoT devices. Pelion 2.0 allows IoT devices to […]

LoDev S76S Board Combines STM32, LoRa and Arm Mbed Support (Crowdfunding)

Arm Mbed Gets a Linux OS for Cortex-A Processors

Mbed Linux OS

Arm Mbed is known as a free, open source platform and operating system that makes it easier to design IoT products based on Cortex-M micro-controllers, but the company figured out it might be a good idea to make something similar for IoT devices based on Arm Cortex-A processor and that’s exactly what Mbed Linux OS is made for. Embedded & IoT devices normally need to be supported for many years,  often optimized for cost and battery life, and make sure security patchsets are applying to your products. Companies often managed to do all those themselves but it’s not the most cost-effective solution, so  instead Arm decided to leverage Linux and offer Mbed Linux OS optimized for IoT devices yo their customers. The solution comes with built-in security, device management (e.g. OTA firmware upgrades) via the Pelion IoT Platform, common development tools for faster time to market, and so on. Some […]

Makerdiary nRF52840 Micro Development Kit Works with OpenThread, Arm Mbed OS, Zephyr OS, Mynewt, etc…

nRF52840 Micro Development Kit

If you want to play around with Bluetooth 5, Nordic nRF52840 is probably one of the best option, and among the development board, $9/$12 Particle Xenon is hard to beat when it comes to value. But if you need a bit more storage, I/Os and features, Makerdiary nRF52840 micro development kit looks like a good candidate to evaluate, especially it supports plenty of frameworks / operating systems such as Arm Mbed OS, Zephyr Project, OpenThread, Mynewt, and others. It’s also the first MCU class board I’ve seen with a USB type C port, although I’m not sure it brings any benefits to this type of hardware.
