Wireless communication device and wireless communication method

A wireless communication method executed by a wireless communication device connected to an electronic instrument and transmitting and receiving MIDI data input and output from the electronic instrument with respect to a different wireless communication device by wireless communication,

• wherein a communication mode in which a master mode and a slave mode are switchable is provided, wherein the master mode is for making an instruction to the different wireless communication device, and the slave mode is for making a response corresponding to an instruction from the different wireless communication device in which the master mode is set,
• wherein the wireless communication method comprises:
• acquiring any of the master mode or the slave mode for the communication mode when connection is established between a paired wireless communication devices constructed by the wireless communication device and the different wireless communication device,
• transmitting a mode setting notification to the different wireless communication device when the communication mode that is acquired is the master mode, and
• setting the master mode as the communication mode when a mode setting permission notification is received from the different wireless communication device after the mode setting notification is transmitted.

• wherein the wireless communication device comprises a processing unit configured to:
• acquire any of the master mode or the slave mode for the communication mode when connection is established between a paired wireless communication devices constructed by the wireless communication device and the different wireless communication device,
• transmit a mode setting notification to the different wireless communication device when the communication mode acquired by the processing unit is the master mode, and
• transmit a mode setting permission notification to the different wireless communication device when the communication mode acquired by the processing unit is the slave mode and when the mode setting notification is received,
• wherein the processing unit acquires any of the master mode or the slave mode for the communication mode again when the mode setting permission notification is not received from the different wireless communication device even if the master mode is acquired as the communication mode and a predetermined first mode setting standby time has elapsed after the mode setting notification is transmitted by the processing unit, and acquires any of the master mode or the slave mode for the communication mode again when the mode setting notification is not received from the different wireless communication device even if a predetermined second mode setting standby time has elapsed after the slave mode is acquired as the communication mode.
