An electronic device according to an embodiment disclosed herein may include a sensor, a short-range communication module, and a processor. The processor is configured to generate first rotation angle information, establish a connection to the external electronic device, receive, from the external electronic device, second rotation angle information and check data uniquely assigned to the second rotation angle information, configure a first time stamp based on the check data and a time of receiving the second rotation angle information, configure a second time stamp based on the check data and a time of correcting the second rotation angle information, compare the first time stamp and the second time stamp to calculate a delay time, correct the second rotation angle information based on the delay time, and generate posture information based on the first rotation angle information and the corrected second rotation angle information.
