Abstract: Disclosed herein are a method for performing, by a first node, a relay function in a Bluetooth mesh network and an apparatus performing the method. The method includes transmitting a first message for activating or deactivating the relay function of the first node to a plurality of neighboring nodes when a specific event is generated and activating or deactivating the relay function depending on whether a first indication message to request the activation of the relay function is received or not in a response to the first message within a first specific time from at least one of the plurality of neighboring nodes. The specific event is one of receiving a command indicating the setting of the relay function, a specific cycle, or receiving a second message for activating or deactivating the relay function from the neighboring nodes.
