Title: METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA USING BLUETOOTH TECHNOLOGY
Abstract:
The present invention relates to a method and an apparatus for a client to transmit and receive data to and from a server by Bluetooth. According to the present invention, a method and an apparatus are provided for forming a Bluetooth low energy (LE) connection with a server; and transmitting, to the server, a first read request message requesting to read a first characteristic including first coupling state information, wherein the first coupling state information is a part of a specific coupling state information indicating a state of coupling between the server and at least one of the devices; receiving, from the server, a first read response message including the first coupling state information; and receiving, from the server, an indication message including changed coupling state information included in a second characteristic if the coupling state has changed, wherein the changed coupling state information indicates the changed coupling state between the server and the at least one device.
