The present disclosure relates to a method and an apparatus for establishing a reconnection between devices by using Bluetooth low energy (LE). In particular, a method performed by a first device comprises the steps of: performing a reconnection parameter negotiation procedure with a second device; transmitting, via a channel determined on the basis of a result of the negotiation procedure, to the second device, a trigger sequence including at least one trigger codeword for requesting the reconnection; and receiving a beacon from the second device in response to the trigger sequence, wherein when the beacon is received, the reconnection between the first device and the second device may be established.

Method and apparatus for establishing connection between devices by using bluetooth low energy technology

Disclosed herein is a method and apparatus for processing A first device for processing a voice command received from at least one device using a Bluetooth low energy technology, comprising: Specifically, a method performed by a first device includes transmitting a first advertising message to a peripheral device; receiving a first request message requesting establishment of an audio channel for transmitting and receiving the voice command from a second device; establishing the audio channel with the second device; and receiving a voice command instructing performance of a particular service from the second device through the audio channel.

Method and apparatus for processing audio signal by using Bluetooth technology

The present invention relates to a method and an apparatus for transmitting or receiving, by a first manager apparatus, data for provision of a particular service in a mesh network of a wireless communication system. The present invention provides a method and an apparatus for: receiving, from a target apparatus, state information related to update of firmware for providing a particular service; transmitting a request message which requests update of firmware of the target apparatus on the basis of the state information; thereafter, selecting a particular channel from multiple channels for transmission of firmware data, wherein the multiple channels are channels configured to transmit or receive data having a predetermined size or larger; transmitting the firmware data through the particular channel; and receiving, from the target apparatus, a completion message which indicates completion of the update of the firmware, wherein the state information includes a version identifier which indicates the current version of the firmware.

Method and apparatus for transmitting or receiving data by using bluetooth low energy technology

Disclosed herein are a method and apparatus for discovering an adjacent device in a wireless communication system using Bluetooth low energy (LE). In particular, the method performed by a first device includes recognizing an advertising channel in which interference exists among three advertising channels constituting a first advertising channel set, transmitting a control message instructing application of a protected mode to a second device, when the advertising channel in which interference exists is recognized, the protected mode indicating a mode for transmitting and receiving a message using a second advertising channel set updated from the first advertising channel set in a non-connection state, and receiving an advertisement message from the second device through the second advertising channel set.
