Claim 0:
1. A data transmission/reception method performed in a data transmission/reception system including a sensing terminal and a user terminal connected through Bluetooth low energy (BLE) communication, the data transmission/reception method comprising operations of:
allowing the sensing terminal to acquire sensing data;
allowing the sensing terminal to sequentially assign a number on the basis of the time at which the sensing data is acquired and store the number in a packet of the sensing data;
allowing the sensing terminal to transmit the sensing data in which the number is stored to the user terminal in a broadcast mode of the BLE communication;
allowing the user terminal to receive the sensing data;
allowing the user terminal to compare the number of the sensing data to the number of prestored sending data; and
allowing the user terminal to store the received sensing data and determine whether to request recovery of sensing data having a specific number according to a comparison result of the numbers.
