origin

The name Bluetooth comes from Danish King Harald Blatand in the 10 century, and his English meaning can be interpreted as Bluetooth.

The founder of Bluetooth is Ericsson, Sweden, which began to develop Bluetooth as early as 1994. During 1997, Ericsson contacted other equipment manufacturers, which aroused their strong interest in this technology. 1In February 1998, five multinational companies, including Ericsson, Nokia, IBM, Toshiba and Intel, formed a special interest group (SIG), and their common goal was to establish a global small-scale wireless communication technology, namely Bluetooth.

The name of Bluetooth comes from Danish King Harald Blatand in the 10 century-translated into English as Harold Bluetooth (because he likes eating blueberries very much, his teeth are blue every day). In the preparatory stage of the trade association, an expressive name is needed to name this high-tech. Industry organizers, after a night of discussion about the history of Europe and the infinite development of science and technology in the future, some people think that it is most appropriate to name it after King Blatter. King Blatter unified Norway, Sweden and Denmark. He is articulate and sociable, just like this upcoming technology, which will be defined as allowing coordination between different industrial fields and maintaining good communication between various system fields, such as computing, mobile phones and automobile industries. So the name is decided.
