1. A method for transmitting and receiving, by a master device, data in a short-range wireless communication system, the method comprising:
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 for transmitting and receiving the data based on the first advertising message, based on a link parameter for a configuration of the shared link,
wherein the shared link includes (i) a first link for data transmission from the 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 is updated in order to add the second slave device as a slave device related to the shared link based on the second advertising message, and
wherein the updated link parameters are configured as different values for each of (i) the first link and (ii) the second link based on the characteristics of the first and second links.
