Abstract: Disclosed are a method and an apparatus for selecting and connecting a gateway by a user device by using Bluetooth low energy technology, and a voice recognition system including a first device, a first gateway, and a voice recognition server. The first device broadcasts a voice signal to a neighboring gateway, the voice signal is forwarded to the voice recognition server by neighboring gateways, and the voice recognition server transmits a connection request message to an optimal gateway by processing the voice signal. After authentication of the voice recognition server is performed, the optimal gateway receiving the connection request message and a user device are connected to each other.

Abstract: Disclosed are a method and apparatus for transmitting and receiving data using a Bluetooth low energy (BLE) technology. A method of transmitting or receiving data using Bluetooth low energy (BLE) in a wireless communication system includes forming Bluetooth LE connection with a second device, establishing an isochronous channel for transmitting an audio packet with the second device and transmitting audio packets to the second device through the isochronous channel using an interleaved method at a specific channel interval. The sequence in which the audio packets are transmitted may be determined regardless of whether acknowledgement (ACK) for each of the audio packets is received from the second device.
