ARM: connected buildings with mbed OS 5.4

The latest release of mbed OS 5.4, delivers new features to enable developers to tackle some of the key challenges they’re facing in applications such as connected buildings. Further, the transformation is in motion in IoT in 2017: New networks and connectivity coming to wide-scale deployments are a major visible signature of this change.  

Through mbed OS 5.4, developers now have the choice, from cellular, Wi-Fi, 802.15.4, BLE, Thread or sub-GHz 6LoWPAN. The mbed OS team also recently demonstrated early features of NB-IoT connectivity at Mobile World Congress in February 2017. As multiple protocol connectivity also impacts storage requirements, mbed OS 5.4 adds flexible filesystem support to address the needs of IoT applications requiring storage within the end node.

Connectivity enhances a building’s responsiveness to internal changes as well as resilience against external challenges. Today, high performing buildings are expected to respond to a myriad of stimuli from the internal environment (changes in lighting, temperature, humidity, CO2, ventilation and occupancy levels), requirements of information technology (structured and unstructured data from the cloud and on premise computers) and demands from operational technology (signals from elevators, security apparatus and heating and cooling systems).

The Thread Group has recently opened testing and product certification for devices taking advantage of Thread connectivity. It results from the first set of software stacks also completing interoperability testing. This enables developers to start creating applications aimed at residential buildings. ARM mbed OS 5.4 makes the recently certified mbed Thread 1.1 stack freely available to developers, and includes solutions for building both end nodes and border routers based on Thread. A Linux-based Access Point to connect Thread networks to the cloud that utilizes the Thread border router is also available.  

OpenAIS, a consortium of Europe’s largest lighting manufacturers, recognizes the vast opportunity for developers to drive differentiation and innovative user experiences in commercial building lighting products and services. OpenAIS is creating a standard for Internet-connected lighting with a defined system architecture and open interfaces. Funded by the European Union, this initiative will deploy mbed OS in its demonstration system showcasing both Ethernet and Thread connectivity for smart lighting with leading lighting systems and controller manufacturers, opening a vast volume of devices for developers to build IoT applications.

The advantages of mbed OS 5.4 apply to more than just smart lighting. An on-demand facilities management demonstration using the LoRA stack that has been integrated into mbed OS 5 will be on display at the ARM booth at Embedded World, illustrating cost and service response benefits.
