    Abstract: Provided are a method for transmitting and receiving data in a short-range wireless communication system, and a device therefor. More particularly, the method comprises the steps of: establishing a connection associated with a first channel for transmitting and receiving first data to and from a second device; establishing a connection associated with a second channel for transmitting and receiving second data, which is different from the first data, to and from the second device; transmitting and receiving, to and from the second device, the first data on the first channel on the basis of a first time interval for transmitting and receiving the first data on the first channel; and transmitting and receiving, to and from the second device, the second data on the second channel on the basis of a second time interval for transmitting and receiving the second data on the second channel, wherein the data transmission and reception on the first channel and the data transmission and reception on the second channel are performed on the basis of the transmission and reception timing of the first data at the first time interval and the transmission and reception timing of the second data at the second time interval.
