A wireless communication system includes a transmitting side equipped with a microcomputer for control, for transmitting data and also includes a receiving side for receiving data. To prevent the receiving side from receiving identical data more than once, a sequence number is automatically incremented every time a frame of transmit data is transmitted. The sequence number is transmitted together with the data. The next process is performed if it is determined that transmission is correctly performed, or the data is transmitted again without incrementing the sequence number if it is determined that the transmission is not correctly performed. The sequence number is returned to an initial value when the microcomputer for control is reset, and dummy data is transmitted together with the initial value immediately after a reset. The data is transmitted together with an incremented sequence number after transmission of the dummy data.
