Mbed OS 5.4 offers IoT developers connectivity choice

As the Internet of Things (IoT) evolves, designers are beginning to look for wide-scale connectivity, using multiple protocols in a single device. ARM introduces the mbed operating system (OS) 5.4 to offer developers the choice, from cellular, Wi-Fi, 802.15.4, BLE, Thread or sub-GHz 6LoWPAN.

The OS will be highlighted at Embedded World 2017 (Nuremberg, Germany, 14-16 March), following demonstration of the early features of Narrow Band IoT (NB-IoT) connectivity at Mobile World Congress in Barcelona, Spain (February 2017).

As multiple protocol connectivity also impacts storage requirements, mbed OS 5.4 adds flexible file system support to address the needs of IoT applications requiring storage within the end node, says ARM.

The Thread Group has recently opened testing and product certification for devices using Thread connectivity, following the announcement of the first set of software stacks to complete interoperability testing. This enables developers to start creating applications aimed at residential buildings. ARM mbed OS 5.4 makes the certified mbed Thread 1.1 stack available to developers, and includes solutions for building both end nodes and border routers based on Thread. A Linux-based access point (AP) to connect Thread networks to the cloud that use the Thread border router is also available.

The ARM mbed ecosystem has enabled several commercial shipping products already based on mbed OS 5, with more in engineering sample and volume testing phases of design and certification. The release of this mbed OS 5.4 delivers new features to enable developers to tackle some of the key challenges in applications such as connected buildings, says ARM.

OpenAIS, a consortium of Europe’s lighting manufacturers, is creating a standard for Internet-connected lighting with a defined system architecture and open interfaces. This initiative will deploy mbed OS in its demonstration system showcasing both Ethernet and Thread connectivity for smart lighting using light systems and controllers.

According to ARM, the advantages of mbed OS 5.4 apply beyond lighting. At Embedded World, it will demonstrate on-demand facilities management using the LoRA stack that has been integrated into mbed OS 5.4.
