The Thread Group said that a new generation of Thread products that meet the 1.1 specification is preparing for a new set of compliance and certification tests.
Do you have any Internet of Things (IoT) devices that support the Thread networking protocol on the market? Regardless of whether they are networked thermostats, toothbrushes, alarms, lighting fixtures... What happened? The Thread Group originally promised to have Thread-enabled products in the second quarter of 2016, but nothing actually.
ECT Group President Grant Erickson said in an interview with EE TImes that the organization decided earlier this year to revise the 1.0 version of the Thread specification (first passed in the summer of 2015) through the "Enhanced Functionality and Use Cases", the follow-up version 1.1. The specifications have been passed in July, and the first generation of Thread products that were built with the 1.0 version of the specification and are ready to pass the original certification process have been withdrawn by the manufacturers.
At the same time, the new generation of Thread products conforming to the 1.1 version of the specification is preparing to pass a new set of compliance and certification tests; Thread Group has announced the initial hardware reference test platform and test suite, and announced that its test lab has All members are open. Thread is a networking protocol built on the open standards of low-power 802.15.4 mesh networks. It is designed to link hundreds of IoT devices and connect them directly to the cloud.
As with all new industry standards, it is never easy to pass a new set of specifications; it is a big project to launch commercial products that do meet the new specifications. More importantly, to verify that the product is functioning properly and truly interoperable, an industry ecosystem is needed to facilitate the participation of everyone involved in promoting new specifications.
The Thread Group has been at the forefront of this battle. About a year ago, the organization claimed that more than 30 IoT products based on the 1.0 version of the Thread specification were undergoing the first wave of certification testing; Chris Boross, president of the Thread Group at the time, said: "We are filling out more products. Full test line."
But then they realized they needed a better set of specifications. So, what are the important updates to the 1.1 version of the Thread specification? Are those changes large enough to justify the withdrawal of the products that have been tested by the supplier? Erickson explained that the 1.1 version of the specification focuses on: 1. Support for changing the function of the network master key; 2. Allowing the application to initiate a network channel change to a new frequency to avoid interference.
Erickson said that there are many changes to the 1.1 version of the specification, but the main goal is: "to achieve better security and toughness;" he described the new version of the specification as "shot a home run" and support the 1.1 version of the specification. The new test platform and test suite are confident that it will be an important watershed for the development of the Thread industry community.
At the same time, Thread Group also announced that test platform vendors including ARM, NXP and Silicon Labs have released the first protocol stacks that meet the specifications; however, Erickson said that although they have passed the Thread 1.1 specification Based on the tests, the interoperability tests of the three vendor protocol stacks are still in progress and are expected to be completed by the end of this year.
And because Thread Group doesn't want the IoT product industry to wait too long, Erickson pointed out: "We are making sure that they have the actual hardware components available for purchase, and that they can provide their testing and diagnostic tools so they can do "homework", Pre-certification of products within the company before sending the product to the compliance testing laboratory."
The Thread Group, a non-profit organization, focuses on making the Thread specification the foundation of the Internet of Things for home and other applications; current supporters of this specification include ARM, Big Ass SoluTIons, Nest Labs, NXP, Osram, Qualcomm, Samsung Electronics, Schneider. Electric, Silicon Labs, Tyco and Yale Security.
