When the processor determines connection of the first wireless device, the processor switches a reception frequency of the communication unit among frequencies, and restart periodic communication with the wireless devices after receiving an advertising signal transmitted from the first wireless device.
Claims18
A wireless communication device comprising:
- a communication unit configured to periodically communicate with wireless devices in first periods;
- and
- a processor configured to determine whether a first wireless device of the wireless devices is connected to the wireless communication device, and when the processor determines that the first wireless device is not connected to the wireless communication device, the processor is configured to switch a reception frequency of the communication unit among frequencies in a second period having a length equal to a length of the first periods, and restart periodic communication with the wireless devices by the communication unit after the communication unit receives an advertising signal transmitted from the first wireless device.
A wireless communication method comprising:
- periodically communicating with wireless devices in first periods;
- determining whether a first wireless device of the wireless devices is connected to a wireless communication device;
- when it is determined that the first wireless device is not connected to the wireless communication device, switching a reception frequency of a communication unit among frequencies in a second period having a length equal to a length of the first periods;
- and
- restarting periodic communication with the wireless devices by the communication unit after the communication unit receives an advertising signal transmitted from the first wireless device.
