Method for transmitting and receiving data in short-range wireless communication system and device therefor

A master device transmitting audio data in a short-range wireless communication system, the master device comprising:

• a transmitter configured to transmit a radio signal;
• a receiver configured to receive the radio signal;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor,
• wherein the at least one computer memory is configured to store instructions that allow the at least one processor to perform operations based on being executed by the at least one processor,
• wherein the operations comprise:
• forming a Connected Isochronous channel Stream (CIS) channel or a Broadcast Isochronous channel Stream (BIS) channel with at least one first slave device;
• forming the CIS channel with at least one second slave device;
• and
• transmitting and receiving data to and from the at least one first slave device and the at least one second slave device based on at least one time interval that is periodically allocated,
• wherein each of the at least one time interval includes at least one sub-time interval,
• wherein the at least one sub-time interval includes (i) a first time interval in which the master device transmits data to the at least one first slave device or the at least one second slave device and (ii) a second time interval in which the master device receives data generated based on a user input from the at least one first slave device or the at least one second slave device,
• wherein the data transmitted by the master device to the at least one second slave device in the first time interval is haptic feedback data related to a service provided to the master device and the at least one second slave device, and
• wherein the data generated based on the user input received by the master device from the at least one second slave device in the second time interval is control data for operating the service provided to the master device and the at least one second slave device.
