determining a range of a frequency band for audio data to be transmitted through the communication link with the external electronic device according to the connection request based on a sampling rate supported by a codec applied to the communication link;

transmitting a result of connection completion of the communication link to the external electronic device; and

dividing the audio data into areas of different frequency bands based on a total frequency band of the audio data and the determined range of the frequency band and transmitting the divided areas to the external electronic device during different periods of time.

10 . The audio data transmission method of claim 9 , wherein

the transmitting during the different periods of time comprises transmitting an area of a lower frequency band of the divided audio data with priority to the external electronic device.

11 . The audio data transmission method of claim 10 , wherein

the transmitting during the different periods of time comprises:

based on audio data of a first frequency band being normally transmitted to the external electronic device during a first period of time, transmitting audio data of a second frequency band higher than the first frequency band during a second period of time after the first period of time; and

based on transmission of the audio data of the first frequency band to the external electronic device during the first period of time failing, retransmitting the audio data of the first frequency band during the second period of time after the first period of time.

12 . The audio data transmission method of claim 9 , wherein

the range of the frequency band is determined based on the sampling rate supported by the codec used for encoding audio data to be transmitted through the communication link.
