In part one of this series, I covered the how the client and server model is used to establish connectivity. The server hosts resources and the client finds and controls resources. Each resource is represented by a type that is standardized by the OIC and includes details such as addresses and access control policies. IoTivity has a layered architecture where each layer performs different functionality. This article will cover each of these layers. Multi-Bearer Support IoTivity supports Bluetooth Low Energy using GATT, Bluetooth EDR (Enhanced Data Rate) using RFCOMM, Dual IPv4/v6 stack, and XMPP (remote access connectivity). All of the details for each of these bearers is hidden in the connectivity abstraction layer. The IoTivity stack has support for these bearers built in by […]

    Open Source Weekly Wrap-Up: April 19 – 24, 2015

    Samsung Launches GearVRf: an Open Source Virtual Reality Framework GearVRf is a new open source rendering library for application development on VR-supported Android devices. The GearVRf API provides simplified access to the Oculus SDK functionality via the Java Native Interface and the GearVRf native library. This project was launched by Samsung as a collaborative effort that involved the Open Source Group. This blog will feature an article next week that covers the work we put into launching this project. Learn more, or get involved through the Gear VRf Wiki. Daily Wayland & Weston Builds For Ubuntu While Canonical is focusing on Mir for Ubuntu’s display server, other developers are still working on alternatives, such as our very own Bryce Harrington. Bryce has established a daily build archive of Wayland and the reference Weston compositor. This makes it easier than ever before to try out the newest Wayland/Weston code on Ubuntu […]
