Wireless communication device, electronic device, and wireless communication method

A wireless communication method performed by a wireless communication device that is connected to an electronic musical instrument and transmits and receives MIDI data input to and output from the electronic musical instrument to and from other wireless communication devices paired through wireless communication at a predetermined communication interval,

• wherein a pair of the wireless communication is formed between the wireless communication device and each of a plurality of the other wireless communication devices, and
• wherein the method comprises:
• setting a communication interval of each pair to a different time interval;
• transmitting the communication interval set in the setting of the communication interval to the corresponding other wireless communication devices;
• and
• setting the communication interval of each pair again when one of the pairs is cancelled to reset the communication interval of each pair, excluding the cancelled pair, to the different time interval.

A wireless communication device that is a first wireless communication device that is connected to a first electronic musical instrument and transmits and receives MIDI data input to and output from the first electronic musical instrument at a predetermined communication interval through wireless communication,

• wherein the first wireless communication device being connected to a second wireless communication device that is connected to a second electronic musical instrument and transmits and receives MIDI data input to and output from the second electronic musical instrument to and from the first wireless communication device at a predetermined communication interval through wireless communication, and
• the first wireless communication device being connected to a third wireless communication device that is connected to a third electronic musical instrument and transmits and receives MIDI data input to and output from the third electronic musical instrument to and from the first wireless communication device at a predetermined communication interval through wireless communication, and
• wherein the wireless communication device comprises:
• a communication interval setting part configured to set the communication interval between the first and second wireless communication devices and the communication interval between the first and third wireless communication devices to different time intervals;
• a communication interval transmission part configured to transmit the communication intervals set by the communication interval setting part to the corresponding second and third wireless communication devices;
• and
• a resetting part configured to execute the communication interval setting part again when the connection to the second or third wireless communication devices is cancelled to reset the communication interval between the first and second wireless communication devices and the communication interval.
