Why can wearable devices rise at this time?

So far, when we talk about wearable devices, we have to mention one parameter: Bluetooth support or wireless networks connected to smartphones. This is the main basis for measuring whether wearable devices will be able to "talk" to the software on smartphones, so have you ever wondered what it means to be able to support Bluetooth for wearable devices? The first thing to explain is what Bluetooth technology is mentioned here. In the past, we used to say "Bluetooth x.0 version", in fact, starting with Bluetooth 4.0, this technology was Bluetooth SIG (Special acquires Group, The development of the Bluetooth technical standard and its authorization to the manufacturer's non-profit organization is renamed Bluetooth Smart or Bluetooth smart Ready. Bluetooth SIG chief Marketing officer Suke Jawanda told Pingwest that the future Bluetooth SIG will also continue to downplay the x.0 concept, emphasizing Bluetooth Smart, because "x.0 is for geeks, Bluetooth Sig hope that ordinary consumers can also understand. Secondly, the requirement of Bluetooth technology is different between wearable device and smartphone. Suke Jawanda with his wrist Fitbit Flex for example, "in the past when we talked about Bluetooth technology and data transmission, the main consideration is similar to Spotify in a longer period of time to transport data requirements, now like Fitbit Flex is to collect data first, In some ' moments ', the data is transmitted to the user's mobile phone, and the two data transmission modes are different. The Low-power technology of Bluetooth Smart can meet this demand. "Suke Jawanda said. Suke Jawanda explained to pingwest that many equipment manufacturers are now stressing their support for Bluetooth low-power technology (Bluetooth low energy), but it is only one of the functions of Bluetooth Smart. Devices that support Bluetooth Smart support Bluetooth Low-power technology. So why should manufacturers emphasize this? Of course, the low energy consumption technology is to give consumers a "provincial power flow" impression, but in another perspective, each product description of their support Bluetooth smart behind is wearable equipment why at this time one of the important reasons for popular--bluetooth Smart's support for operating systems and hardware devices determines whether wearable devices can transfer data to software at a lower cost, and then how to deal with the data after the software has been obtained. According to Suke Jawanda's introduction, Bluetooth Smart's support for wearable devices is divided into hardwareand software. Take Fitbit, for example, if Fitbit develops a new product that supports Bluetooth smart and requires software to support Bluetooth Smart from iOS or android--operating system level, Apple is from iOS 5 (iPhone 4S and above versions of mobile phones) are starting to support Bluetooth Smart, and Google did not begin to support Android until 4.3. That's why Samsung, when it publishes its smart watch Galaxy Gear, says it can only "connect" to some of its Galaxy phones. "We talked to Apple and Google very early on. and Apple was in 2010, when Steve Jobs was still alive, and the first reaction they heard from Bluetooth Smart was if Apple announced the news, ' How would this thing be reflected in Steve Jobs ' ppt? ' I told them it was like their app Store, which was just beginning to be used and would attract more and more developers. Fortunately, the partnership soon became possible, with Apple's devices supporting Bluetooth Smart after iOS 5, allowing later wearable devices to work with apps in the iphone and ipad. "Suke Jawanda revealed that Google was late to accept that they were in touch with Google when Andy Rubin was still in charge of Android, but because of Google's delay in agreeing to cooperate, some hardware manufacturers had to find a Bluetooth SIG unilaterally , "As far as I know, Samsung has started to do it by itself, so the result is that hardware manufacturers can only add Bluetooth Smart to their branded handsets, and if your bracelet is connected to an Android phone, you may not be able to switch to an Android phone." Wearable equipment manufacturers are also afraid to do Android software, to be a fit. Android's fragmentation problem is highlighted here, with Google adding Bluetooth Smart to Android 4.3 to create a unified standard from the operating system level. upgrades to Android more than 4.3 of mobile phones are no longer facing these problems. So, since then, the problem of data transfer between wearable devices and smartphones has been solved. Of course, Bluetooth Smart is not the only reason, but there are wearable devices that can transmit data in other ways, such as wireless networks, but you know that people can't always be in a wireless network environment. What about cars besides wearable equipment? What else can you do besides using Bluetooth to pick up the phone? "Now we know that the car can do is through the Bluetooth voice operation, phone calls, in the future we imagine that with Bluetooth technology can no longer use the key, your mobile phone can be used as a car key; another is to use more sensors to collect data, so that the car and the car ' dialogue ', for example, your car can know the speed of three cars, when they slow down your car can remind you in front of the car is slowing down may be what happened. "But the biggest problem here is the technology lag in the automotive industry, such as the new technology you see in the Automotive field, the real application to production and promotion is probably 2-3 years later, and people to buy a car is expected to take 10-15 years, That is, you may not be able to experience the new technology in the automotive field for 10 years after you bought a car, and there is no good solution to the problem. "Suke Jawanda said.
