Problems solved by technology

However, if advertisement packets carrying a large amount of data are continuously broadcast regardless of the presence or absence of a device receiving the advertisement packets, it will become useless power consumption.
In addition, if the time interval for broadcasting advertisement packets is widened in order to suppress power consumption, the time required for one cycle of intermittent operation will become longer due to the large amount of data in the advertisement packets, and the responsiveness of information transmission will decrease.

Embodiment Construction

[0024] Embodiments will be described below with reference to the drawings.

[0025] figure 1 It is a diagram showing a configuration example of the radio communication system 1 according to the embodiment. exist figure 1 In the configuration example shown, the wireless communication system 1 is constituted by a beacon device 100 and a smartphone 200 . The beacon device 100 and the smartphone 200 perform wireless communication with each other based on Bluetooth (registered trademark) Low Energy (hereinafter referred to as BLE). BLE is a standard (mode) developed for the purpose of low power consumption in a short-range wireless communication standard called Bluetooth (registered trademark). Furthermore, in this embodiment, it is assumed that the beacon device 100 and the smartphone 200 operate in accordance with the Bluetooth (registered trademark) 5 standard. In this embodiment, based on BLE, the beacon device 100 operates as a slave that transmits an advertisement packet ...

Abstract

The invention provides a wireless communication device, a wireless communication method, and a storage medium. The wireless communication device (100) includes a wireless communicator (103) that wirelessly communicates with other wireless communication device (200), and a processor (101). The processor (101) controls the wireless communicator (103) to broadcast first transmission information on which data with a first maximum size is deliverable, and controls, upon the wireless communicator (103) receiving a request in response to the first transmission information from the other wireless communication device (200) that received the first transmission information, the wireless communicator (103) to transmit second transmission information on which data with a second maximum size is deliverable to the other wireless communication device (200). The second maximum size is larger than the first maximum size.

Description

technical field [0001] The technical field of the present invention relates to wireless communication devices, wireless communication methods, and storage media. Background technique [0002] Conventionally, in Bluetooth (registered trademark) Low Energy (BLE), which is one of the short-range wireless communication standards, it is known that a slave device broadcasts intermittently at predetermined time intervals in order for the master device to discover its own device. Advertisement packet (for example, Japanese Patent Laid-Open No. 2012-142877). [0003] In the existing BLE, advertising data of up to 31 bytes is carried in the advertisement packet, but in the new version (Bluetooth (registered trademark) 5) released in December 2016, a maximum of 254 bytes can be carried in the advertisement packet advertising data. However, if advertisement packets carrying a large amount of data are continuously broadcast regardless of the presence or absence of a device receiving th...
