(S1212). Then, it is determined whether or not all the data has been transmitted (S1213). Here, if it is determined that all the data has not been transmitted, the process returns to step S1212, and the subsequent processing is repeated. On the other hand, if it is determined in step S1213 that all data transmission has been completed, the BLE connection is disconnected (S1214) after waiting for the communication termination request from the smartphone 20, and the series of processes is terminated.
