Wireless communication system and wireless communication method

A wireless communication method, which executes a wireless communication between a master device and a plurality of slave devices;

• each of the plurality of slave devices executing a wireless communication with the master device using a communication channel sequentially selected from multiple communication channels, the wireless communication method comprising:
• determining, in the wireless communication between the master device and each of the plurality of slave devices, a communication quality of each of the multiple communication channels;
• determining at least one target communication channel to be used for the wireless communication based on a determination result of the communication quality of each of the multiple communication channels;
• and
• repeatedly selecting, from the plurality of slave devices, an execution target of determination of the at least one target communication channel to be used for the wireless communication.

A wireless communication system comprising:

• a master device;
• a plurality of slave devices, each of which executing a wireless communication with the master device using a communication channel sequentially selected from multiple communication channels;
• a computer-readable non-transitory storage medium;
• and
• a microcomputer, by executing a program stored in the computer-readable non-transitory storage, configured to:
• determine, in the wireless communication between the master device and each of the plurality of slave devices, a communication quality of each of the multiple communication channels;
• determine at least one target communication channel to be used for the wireless communication based on a determination result of the communication quality of each of the multiple communication channels;
• and
• repeatedly select, from the plurality of slave devices, an execution target of determination of the at least one target communication channel to be used for the wireless communication.
