PROBLEM TO BE SOLVED: To provide a wireless communication system allowing a master unit to know a receiving state of slave units without expending much effort. SOLUTION: During wireless connection between a master unit 100 and a slave unit 200, the master unit 100 transmits a request for receiving state notification to the slave unit 200 (step S307). Upon receipt of the request for receiving state notification, the slave unit 200 measures received electric field strength in communication with the master unit 100 to transmit the measured value to the master unit 100 as receiving state information. The master unit 100 associates the receiving state information notified from the slave unit 200 with the number of the slave unit for storage (steps S308 to S309). Upon completion of transmission to all slave units, all receiving state information stored in a storage unit 104 are displayed on displaying means externally mounted after they are associated with the number of the slave units (steps S311 to S313). |
