Dig into IoT with 41 OpenIoT Summit presentations
Apr 14, 2016 — by Eric Brown 1,534 views
Slide decks from 41 OpenIoT Summit talks are now online, from sessions including AllSeen, Brillo, mBed, Iotivity, Tizen, Weave, Zephyr, and IoT security.
Last week, we pointed you to 50 slide decks released by the Linux Foundation from the Embedded Linux Conference (ELC), held in San Diego in April 4-6. Now, the non-profit Linux advocacy organization has released 41 more slide presentations, this time from the inaugural OpenIoT Summit track co-located with ELC.

There’s a wealth of valuable info in these 41 slides, with plenty of techno-stuff that’s new to us, and perhaps to you to. This is especially true of microcontroller-based Internet of Things boards and operating systems, which we are beginning to explore as a consequence of the growing proliferation of IoT devices. Clearly, there’s a lot more to IoT than Linux-based home automation hubs and Raspberry Pi’s.
Here’s a quick look at three topics covered in the OpenIoT Summit slide decks linked to farther below:

- Iotivity — The Open Connectivity Foundation (OCF) was announced in February, built upon the earlier Open Interconnect Consortium (OIC) and its Iotivity IoT connectivity framework. The OpenIoT Summit featured several Iotivity sessions, including a keynote from the OCF’s Mike Richmond. Meanwhile, Samsung’s Phil Coval showed how to combine Iotivity with Tizen, and Affinegy CTO Art Lancaster discussed “AllSeen Alliance, AllJoyn and OCF, IoTivity — Will We Find One Common Language for Open IoT?” The Affinegy presentation includes a mind-boggling graphic showing all the competing and overlapping IoT interoperability efforts vying for our attention (see above).
- Brillo/Weave — The lightweight, Android-based Brillo OS for IoT, as well as the related Weave networking protocol, may be Google-driven projects, but they’re also open source, and they count numerous tech companies among their contributors. Intel, which is building an Edison Kit for Brillo, sent its Brillo Architect, Bruce Beare, to the OpenIoT Summit to provide a two-part introduction to both Brillo and Weave. Beare offered an overview of the technologies, compared Brillo with the Yocto Project based Ostro distribution for IoT, and compared Weave to Iotivity. He also discussed hardware options, including the Edison kit, an expansion kit for Intel’s MinnowBoard Max, and Aaeon’s Up board. Part two’s “Deep Dive” delved into Brillo HAL details and Weave sensor interactions, and offered a number of coding examples.
- Zephyr — Intel Security Researcher Constanza Heath offered up a “Zephyr Project Security Update” presentation, one of many sessions at the OpenIoT Summit that proposed various solutions for the growing challenge of securing IoT devices. Before digging in to security, Heath provided an interesting overview of the Linux Foundation’s Zephyr open source, MCU-focused RTOS for IoT, and included several architecture diagrams we haven’t seen before (see image below). There were also separate sessions on a Zephyr overview and Zephyr power management. As for security, the chief solution is a new Tinycrypt sub-project from Intel Labs that offers a much smaller footprint than cryptographic libraries like OpenSSL.
