The annual CES (Consumer Electronics Show) opened in Las Vegas on January 6, 2016. As a world-renowned science and technology event, the concepts discussed in CES will become a hot topic in the next two to three years. However, in this CES, which seems to have no core theme, there are many things that are observed by interested people: the Internet of things, smart home, virtual reality, etc. More importantly, the combination of Internet of things and cloud computing. "Lazy economy" is being talked about by more and more people, or will become the new economic growth point of smart home in the next few years. An interesting phenomenon is that the concept of the lazy economy is very popular both at home and abroad. Although o2o has been used for many times since the beginning of the year, and now it has been slightly eased, the concept never seems to cool down. As Shahid Ahmed, a senior executive of PWC, said, "in the field of Internet of things, we have reached a turning point: the integration of consumer experience, digital technology and sensor technology." Fortunately, with the continuous development of related technologies, the smart home industry based on the home Internet of things can capture the "lazy economy" as a new growth field - the convenient life at your fingertips, which is the choice of the middle class who cares about saving time and is willing to try. What's more, "lazy people" are not idle, but to further liberate more time and energy to invest in more worthy areas. This coincides with the original intention of smart home interest: to make people's lives truly free and convenient through technology. What the "lazy man" requires is to work out the most reasonable scheme by intelligent calculation according to the actual situation in the simplest operation as possible, and to realize the requirements of accuracy and complexity as efficiently as possible. This requires not only technical support, but also the thinking close to the user's actual experience, otherwise it will become a chicken ribs. In fact, in the smart home industry, sharp manufacturers at home and abroad have caught the pass of this node, and timely launched a variety of products that are convenient for the user's life: sweeper robot, automatic fast food machine, intelligent lighting adjustment, intelligent door lock, etc. In terms of smart door lock, this CES is like the W2 walnut smart lock of CEI, which realizes the remote door opening and closing service of "cloud key", and provides a good experience for "lazy people" to break the space limit. It is worth noting that local excellent original manufacturers also have outstanding performance in the field of smart home, and they have also upgraded and fermented in the domestic market in recent years. There is no doubt that smart home based on "lazy economy" has great development potential. According to the latest report released by research and markets, it is predicted that the global smart home market will grow ...

Smart locks and smart sensors have become more and more trendy. Developers can spend a huge amount of time creating and connecting these popular Internet of Things (IoT) products to the cloud via gateways using wireless technologies such as Bluetooth® low energy(LE). Choosing an easy-to-use cloud service that offers powerful functions, steadiness and multiple cloud-security features can also be a challenge, so RF-star and TI worked with Alibaba to provide support for the Ali Cloud Link IoT platform on RF-star Bluetooth low energy CC2640R2F wireless module. RF-star provides a sample application for the CC2640R2F module software development kit (SDK) to support Ali Cloud Link. Through this sample application, you can receive the specific Alibaba profile, which contains a range of security features, over-the-air (OTA) support and good performance for compatibility with iOS and Android platforms. For example, you can use the secure hash algorithm (SHA) 256 security feature and the CC2640R2F wireless module’s true random number generator (TRNG) to generate keys for Advanced Encryption Standard (AES) encryption, which is included in the CC2640R2F device’s hardware encryption engine. This ensures that every communication session gets a different key to improve the security performance for data transmission. With a few simple application programming interfaces (APIs), you can build up a secure Bluetooth low energy product. The Alibaba OTA protocol is fully supported in this sample application. Compatibility with different Android mobile phones has been optimized, especially for China-brand Android phones. Figure 1 shows the architecture of a sample application with theTI CC2640R2F SDK.
