2. Search for KJSTAR on the mobile phone, and click KJSTAR on the mobile phone to connect. The KJSTAR software on the mobile phone appears in blue font, indicating that it is connected.
3. Then enter the camera software of the mobile phone, and you can take a selfie wirelessly. Please control the whole process within 40 seconds.
4. This wireless selfie stick can also be directly used as a Bluetooth selfie remote control. Even if the phone is not placed on the selfie stick, it can be used to take selfies in other places (within 10 meter), which is very good.
Bluetooth (Bluetooth? ): is a wireless technical standard, which can realize short-distance data exchange between fixed equipment, mobile equipment and personal area network of buildings (using UHF radio waves in ISM band of 2.4-2.485 GHz). Bluetooth technology was first invented by telecom giant Ericsson in 1994 as a substitute for RS232 data line. Bluetooth can connect multiple devices, which overcomes the problem of data synchronization.
Today, Bluetooth is managed by the Bluetooth Special Interest Group (SIG). The Bluetooth Technology Alliance has more than 25,000 member companies in the world, which are distributed in many fields such as telecommunications, computers, networks and consumer electronics. IEEE lists Bluetooth technology as IEEE 802. 15. 1, but this standard is no longer maintained. Bluetooth Technology Alliance is responsible for supervising the development of Bluetooth profile, managing certification projects and maintaining trademark rights. The manufacturer's equipment must meet the standards of Bluetooth Technology Alliance before it can enter the market in the name of "Bluetooth equipment". Bluetooth technology has a set of patented networks that can be distributed to devices that meet the standards.
The word "Bluetooth" is the Scandinavian word Bl? tand / Bl？ Tann (that is, old Norwegian blát? Nn), which is the nickname of harald Bluetooth, a king in 10 century. He unified the disputed Danish tribes into a kingdom, and it is said that he also introduced Christianity. The idea of naming Bluetooth after this was first put forward by Jim Kardach in 1997. Kardach has developed a system that allows mobile phones to communicate with computers. He was inspired by the historical novel Long Ships written by Frans G. Bengtsson, which described Viking and Harald Bluetooth King in harald, which means that Bluetooth will also unify the communication protocol into a global standard.
