Publication number: 20200314925Abstract: A network system includes an electric apparatus and a communication terminal. The electric apparatus emits a non-connectable beacon by a first communication scheme compliant to Bluetooth (registered trademark). The communication terminal outputs a notification for connection based on the non-connectable beacon. The electric apparatus emits a connectable beacon by the first communication scheme in a case where the electric apparatus directly accepts an operation of a user. In a case where the communication terminal receives the connectable beacon after the user responds to the notification, the communication terminal and the electric apparatus connect to each other by the first communication scheme.Type: ApplicationFiled: March 23, 2020Publication date: October 1, 2020Inventors: AOGU FUJII, TAKUYA NOZU, TSUYOSHI IWAMOTO
