Embodiment approach 1

[0026] Such as figure 1 As shown, the radio communication system 1 according to the embodiment includes a transmitting terminal 100 and a receiving terminal 300 . The transmitting terminal 100 and the receiving terminal 300 are wireless communication devices that perform wireless communication with each other based on Bluetooth Low Energy (registered trademark) (hereinafter referred to as BLE, Bluetooth Low Energy). BLE refers to a standard (mode) developed for the purpose of low power consumption among short-range wireless communication standards called Bluetooth (registered trademark). Furthermore, in Embodiment 1, it is assumed that the transmitting terminal 100 and the receiving terminal 300 operate in accordance with the Bluetooth (registered trademark) 5 (Bluetooth (registered trademark) core specification version 5.0) specification.

[0027] In wireless communication system 1 according to Embodiment 1, transmitting terminal 100 stores large-capacity data (where the siz...

Abstract

The invention provides a wireless communication apparatus, a wireless communication method, and a storage medium. The wireless communication apparatus includes a wireless communicator capable of broadcasting an extended advertising packet having a large transmittable capacity and a compatible advertising packet having a transmittable capacity smaller than the extended advertising packet, and a processor. The wireless communicator periodically broadcasts the extended advertising packet based on a command from the processor. The processor sets offset information for acquiring of a time at whichthe extended advertising packet is receivable in an offset notification packet that is the compatible advertising packet, and broadcasts the offset notification packet via the wireless communicator. The offset information is set based on a transmission timing of the offset notification packet and a transmission timing of the extended advertising packet.

Description

technical field [0001] The present invention relates to a wireless communication device, a wireless communication method, and a storage medium storing a program. Background technique [0002] It is known that in Bluetooth (registered trademark) (BLE: Bluetooth Low Energy), which is one of the short-range wireless communication standards, in order for the host device to discover this device, it is stipulated that in the non-connection (connection less) A function of intermittently broadcasting advertising packets at predetermined time intervals (for example, Japanese Patent Laid-Open No. 2012-142877). [0003] In the existing (before Bluetooth (registered trademark) 5) BLE, advertisement data of up to 31 bytes can be carried in the advertisement packet, but in Bluetooth (registered trademark) 5 released in December 2016, extended advertisement can be used Periodic Advertising (Periodic Advertising) of packets (groups on the Secondary Advertising Channel). By using this exten...
