Today the Contiki team announced the release of Contiki 3.0, the latest version of the open source IoT operating system! The 3.0 release is a huge step up from the 2.x branch and brings support for new and exciting hardware, a set of new network protocols, a bunch of improvements in the low-power mesh networking protocols, along with a large number of general stability improvements. This is, by far, the best Contiki release ever!
Contiki is the open source operating system for the Internet of Things, used by developers to bring low-power wireless connectivity to their products and projects. Read more about Contiki here.
Since the the previous 2.7 release, which came out in November 2013, the Contiki team has merged some 500 pull requests with new code, bug fixes, and improvements.
As the wireless world evolves, so does its hardware. Recently, many new Systems-on-a-Chip (SoCs) have been released, which makes hardware design much easier, as you only need a single chip for both radio communication and control.
Contiki 3.0 adds support for two new interesting hardware platforms: the Texas Instruments Sensortag and the Zolertia ReMote.
