    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: The present invention relates to a method for controlling a first device performed by a control device using the Bluetooth. The present invention provides a method and apparatus including receiving a first advertising message from a first device; calculating a first distance value that indicates a distance with the first device based on the first advertising message; receiving a second advertising message from a second device when the first distance value is smaller than a threshold value preconfigured to determine a proximity with the control device; and calculating a second distance value that indicates a distance with the second device based on the second advertising message, where a Bluetooth connection is established between the first device and the second device when the second distance value is smaller than the threshold value.
