  • Patent number: 11830464
    Abstract: A wireless communication device and a wireless communication method are provided. When a master mode is set in a mode memory, a mode setting notification is transmitted to a different wireless communication device. When a mode setting permission notification for the mode setting notification is received from the different wireless communication device, the master mode is settled as a communication mode, and the master mode is set in the mode memory. When a slave mode is set in the mode memory and when a mode setting notification is received from the different wireless communication device, the slave mode is settled as the communication mode, the slave mode is set in the mode memory, and a mode setting permission notification is transmitted to the different wireless communication device. Thus, the communication mode can be automatically set in a pair of wireless communication devices.

  • Patent number: 11663999
    Abstract: A wireless communication device and a wireless communication method capable of curbing occurrence of latency even when performing wireless communication at predetermined time intervals are provided. MIDI data is transmitted and received by communication (B) performed through a wireless module during an intermission between communications (A) performed at predetermined time intervals through the wireless module. Accordingly, a communication speed for wireless communication is improved. Therefore, compared to a case in which wireless communication is performed by only the communication (A), MIDI data can be quickly transmitted and received, and thus occurrence of latency can be curbed.
