Abstract: A home appliance connection method according to embodiments of the present invention may comprise the steps of: setting a wireless mode to a station mode; periodically searching for a wireless network on the basis of the station mode; and, when a wireless network search request is received from a terminal device, transmitting found wireless network information to the terminal device. A home appliance connection method according to embodiments of the present invention may further comprise a step in which the terminal device receives found wireless network information, wherein the found wireless network information of the terminal device may be information from which a wireless network not associated with a home appliance for the terminal device has been filtered. A home appliance connection method according to embodiments of the present invention may further comprise a step of, when the wireless mode is a station mode, periodically changing the wireless mode into an access point (AP) mode and periodically transmitting a beacon message to the terminal device on the basis of the AP mode. A home appliance connection method according to embodiments of the present invention may comprise a step of receiving a first advertising message on the basis of a Bluetooth from the terminal device, wherein the first advertising message may comprise a home appliance registration request. Furthermore, a home appliance connection method may comprise the steps of: transmitting a second advertising message to the terminal device on the basis of the Bluetooth in response to the first advertising message; and searching for a wireless network in response to the first advertising message.
