PROBLEM TO BE SOLVED: To provide a short-range radio communication apparatus of, for example, a Bluetooth system, capable of securing the reliability and the validity of transmission data.SOLUTION: When a master-side opposite information apparatus 20 exists at an adjacent position, a short-range radio communication apparatus 10 of the Bluetooth system, which becomes capable of data communication, alternately performs an alternate monitoring operation of receiving from the master-side opposite information apparatus 20 the transmission data to which an A2DP profile is applied as a DTMF signal, and thereafter, using an AVRCP profile, returning to the master-side opposite information apparatus 20 an ACK signal or a NAK signal, as response data which indicates the analysis result of the transmission data, or of transmitting to the master-side opposite information apparatus 20 the transmission data to which the A2DP profile is applied, and thereafter, using an AVRCP profile, receiving response data which indicates the analysis result of the transmission data from the master-side opposite information apparatus 20.SELECTED DRAWING: Figure 1 |
