Abstract

A communication method S100 comprises: a step S120 for writing the BD address of a communication device and the device ID of an information processing device in a memory of the information processingdevice, and thereafter breaking a connection between the communication device and the information processing device; a step S 130 for transmitting, to each of a plurality of information processing devices 20, a broadcast command including a BD address and a device ID; and a step S140 for, when the BD address and device ID written in the memory of the information processing device and the BD address and device ID included in the broadcast command match, executing processing complying with the broadcast command.

Description

technical field [0001] The present invention generally relates to a communication method and a communication system, and more particularly, to a communication method and a communication method capable of improving the reliability and security of communication between a communication device and an information processing device and individually controlling each of a plurality of information processing devices Communication Systems. Background technique [0002] In recent years, a field called IoT (Internet of Things: Internet of Things) has attracted attention. IoT, as its name implies, means that all devices around you are connected to communication networks such as the Internet and LAN (Local Area Network). By making full use of IoT, it is possible to acquire various information and operate devices at a lower cost than before. [0003] The reduction in size and power consumption of devices capable of wireless communication, and the advancement of wireless communication tec...
