  • Publication number: 20230179980
    Abstract: Provided in the example embodiments are a communication method employing a Bluetooth network, and a node and a communication system applying the same. The communication method applicable to a Bluetooth end node includes: if there is a relay node in neighboring Bluetooth nodes, performing data communication via the relay node; and if there is no relay node in the neighboring Bluetooth nodes, sending a relay configuration request message by broadcast to request a gateway node to select and configure a relay node from the neighboring Bluetooth nodes. The communication method employing a Bluetooth network, and the node and the communication system applying the same provided in the example embodiments can flexibly configure a minimum number of relay nodes according to an actual network topology, thereby preventing the problem in which many relay nodes in a network result in forwarding of a large number of broadcast packets and consequently affect the throughput of the network.
