"With the further development of bluetooth, SIG wants to go beyond the previous audio programme, which aims to achieve more automation, including building, industry and commerce. First, bluetooth is point-to-point, point-to-multiple connections, multicast channels, and the latest mesh network. SIG ADAPTS to their application by modifying current specifications according to specific manufacturer's application requirements. For example, how can the automated applications of buildings extend and extend the scope of their connections? How to make high-speed connections and speed up operations?" On September 26-27, 2017, bluetooth Asia conference was held at the shenzhen convention and exhibition center, said Chuck Sabin, senior strategic planning director for bluetooth technology alliance. The ambition of bluetooth has been connected from electronic devices to the Internet of things! The development and evolution of bluetooth is ubiquitous in bluetooth 3.0, 2.0, 1.0 era, mobile phone, ipad, audio, headset, mouse, keyboard and so on. In the age of 4.0, the low-power bluetooth broadcast technology enables beacon beacons to be spread across commercial locations, location information tracking, and service information push to further broaden the application scene of bluetooth technology. In July, the bluetooth technology alliance launched a bluetooth mesh networking technology. This is a landmark inflection point for the development and application of bluetooth technology that can only communicate via point-to-point communication and broadcast communications. Chuck says the market for bluetooth mesh will be very broad. New wireless mesh network support many-to-many communication transmission equipment, and improve the communication effectiveness of building large coverage, is suitable for the need for thousands of equipment in a reliable and safe transmission under the environment of Internet solutions. Bluetooth mesh networking technology will be widely used in the fields of building automation, industrial automation and sensor networks. Why choose bluetooth? Currently, there are many communication technologies in Internet of things, and WiFi, ZigBee and nb-iot technology have a wide range of applications in the field of Internet of things. So, why do we need to choose bluetooth? For this, Chuck Sabin says the Internet of things connections can be based on different scenarios. Bluetooth can achieve multi-level connections, such as audio, positioning, and application connectivity in the Internet of things, which can enable application vendors to better meet customer needs. In addition, bluetooth is a very mature technology, and bluetooth device shipments of 5.6 billion a year, bluetooth technology has widespread application in mobile phones, tablets and other PC support equipment and wearable devices. At the same time, products that meet the technical standards of bluetooth, global connectivity, are a great choice for people who want to develop products. What areas of connectivity will bluetooth be committed to? Building automation Advanced building control and automation systems are used for lighting, heating, cooling and safety in scenarios such as smart home and smart offices. By 2022, according to ABI research, the number of bluetooth connections in building automation will reach 1 billion a year. Through bluetooth technology and mesh network, bluetooth will realize the intelligence of places like home and office. Industrial automation and farmland data acquisition Wireless mesh network according to its features, and low power consumption performance of bluetooth application scenario is very suitable for wireless sensor network, such as industrial automation, found in all corners of the factory of all kinds of sensors to collect equipment information for equipment management and predictive operations. In addition, through the bluetooth mesh, the farmland data can be collected in real time and the agriculture is managed better. Asset tracking location Hospitals, factories and other complex application scenario, via bluetooth beacon, can for the management of the assets of the assets and equipment and track, thus protecting expensive equipment, improve equipment utilization. Era of Internet of things application scenario of fragmentation, the characteristics of different communication technology based on the characteristics of its own applicable in different scenarios, everyone is to do the same thing: committed to the Internet of things better connection and successful application. As Chuck said, bluetooth is willing to work with other developing iot applications to promote the success of the Internet of things. Bluetooth is growing, and so is the Internet of things.
