The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and an apparatus for synchronizing communication between nodes in a bluetooth low energy (BLE) mesh network. In the network, a node is configured to generates a seed value based on at least one of own transmission parameter, wherein the seed value indicates next data advertisement instance of corresponding node. Further, the seed value is used for communicating with other nodes (i.e. 1-hop neighbor nodes) in the network. Based on data transfer requirements of the node, the node synchronizes own data transmission and reception settings, such that no two nodes transmit data at the same time.
