Embodiment Construction

[0019] Hereinafter, embodiments will be described based on the drawings.

[0020] Such as figure 1 As shown, the communication system 1 of the embodiment includes an upper terminal (communication device) 100, lower terminals (terminals) 200A to 200C, and a scanning terminal 300. The upper terminal 100, the lower terminals 200A to 200C, and the scanning terminal 300 communicate with each other based on Bluetooth Low Energy (registered trademark) (hereinafter referred to as BLE). BLE refers to a specification (mode) established for the purpose of low power consumption in the short-range wireless communication specification called Bluetooth. Furthermore, in this embodiment, the upper-level terminal 100, the lower-level terminals 200A to 200C, and the scanning terminal 300 operate according to the Bluetooth 5 standard. In this embodiment, the upper-level terminal 100 transmits information related to the advertisement described later to the lower-level terminals 200A to 200C, and bro...

Abstract

A communication device according to the invention includes: a communicator that communicates with a terminal and broadcasts to a scanner terminal that receives data from the terminal; and a controllerthat controls the communicator to transmit to the terminal, data that is included in an advertisement that is scheduled to be broadcast by the terminal and transmission information regarding the advertisement and cause the communicator to broadcast the transmission information that is intended to cause the scanner terminal to receive the advertisement that is broadcast by the terminal.

Description

Technical field [0001] The present invention relates to a communication device, a scanning terminal, a communication system, a communication method, and a storage medium. Background technique [0002] Previously, in Japanese Patent Laid-Open No. 2012-142877, it was disclosed that in Bluetooth Low Energy (registered trademark) (Bluetooth Low Energy: BLE), which is one of the short-range wireless communication specifications, the slave device would Broadcast advertising packets intermittently at specified time intervals. [0003] In the existing BLE, advertising packets can be loaded with a maximum of 31 bytes of advertising data. In the new version (Bluetooth 5) released in December 2016, advertising packets can be loaded with a maximum of 254 bytes of advertising data. By using the periodic advertising (Periodic Advertising) and secondary advertising (Secondary Advertising) added to Bluetooth 5, large-capacity data can be sent periodically without connection. The period of the pe...
