Home appliance, method of controlling the same, and method of controlling mobile device communicating with home appliance

A home appliance comprising:

• a communication module;
• at least one memory storing at least one instruction;
• and
• at least one processor connected to the at least one memory,
• wherein the at least one processor is configured to execute the at least one instruction to:
• during a first time interval, via the communication module, by performing Bluetooth low energy (BLE) advertising, output a BLE advertising packet including service set identifier (SSID)-related information related to an SSID of a software enabled access point (Soft AP) of the home appliance in a new product state in which the home appliance has not been registered in a server, and
• during the first time interval, output a Wi-Fi beacon of the Soft AP via the communication module,
• based on receiving a connection request for the Soft AP from a mobile device after outputting the Wi-Fi beacon, establish a Wi-Fi communication connection between the mobile device and the Soft AP,
• receive, from the mobile device via the Wi-Fi communication connection, a control signal related to an initial setting operation of registering the home appliance in the server,
• perform the initial setting operation, based on the received control signal, and
• in the case that the Wi-Fi communication connection between the mobile device and the Soft AP is not initiated during the first time interval, repeat the actions of the first time interval until the establishing of the Wi-Fi communication connection between the mobile device and the Soft AP is initiated.
