    Abstract: A method of transmitting and receiving data in a short-range wireless communication system, and a device therefor are provided. More specifically, a method of receiving, by a master device, data in a short-range wireless communication system comprises transmitting, to a slave device, a read request message requesting a reading of at least one data transmission period supported by the slave device; receiving, from the slave device, a read response message including information on the at least one data transmission period supported by the slave device; receiving, from the slave device, a message indicating a selection of a specific content among at least one content related to a service provided by the master device; transmitting, to the slave device, a message for configuring a specific data transmission period among the at least one data transmission period supported by the slave device to the slave device based on (i) a type of the selected specific content and (ii) the information on the at least one data transmission period supported by the slave device; and receiving, from the slave device, the data based on the configured specific data transmission period. The method comprises, based on the type of the selected specific content being changed, transmitting, to the slave device, a message for reconfiguring the data transmission period of the slave device based on the changed type of the content.

    Abstract: Provided are a method for transmitting and receiving data and a device for same in a short-range wireless communication system. More specifically, the method comprises the steps of: receiving, from a first slave device, a first advertising message for providing a service related to transmitting and receiving the data; forming a shared link, which is for transmitting and receiving the data and is formed on the basis of the first advertising message, on the basis of link parameters for the configuration of the shared link, the shared link including (i) a first link for data transmission from a master device to a slave device, and (ii) a second link for data transmission from the slave device to the master device; and receiving, from a second slave device, a second advertising message for providing the service. wherein the link parameters applied to the shared link are updated on the basis of the second advertising message in order to add the second slave device as a slave device related to the shared link, and the updated link parameters are configured as different values for each of (i) the first link, and (ii) the second link on the basis of the characteristics of the first and second links.
