摘要： Disclosed in the present disclosure is a method for provisioning a Bluetooth Mesh network, used for provisioning a plurality of non-provisioned devices, so as to add the plurality of non-provisioned devices to the Bluetooth Mesh network. The method includes: provisioning, by a top provisioner, surrounding non-provisioned devices of the top provisioner, so as to add the surrounding devices to the Bluetooth Mesh network as nodes; selecting, by a top provisioner, the one or more newly added nodes to be configured as one or more temporary provisioners; provisioning, by each of the one or more temporary provisioners, surrounding non-provisioned devices, so as to add the surrounding devices to the Bluetooth Mesh network as nodes; and completing, by the top provisioner and each of the one or more temporary provisioners, the provisioning of the plurality of non-provisioned devices. The method of the present disclosure may greatly improve the average provisioning speed of device, and ensure the unified allocation of key network information and the compatibility of provisioning on the premise of ensuring the provisioning security of the Bluetooth Mesh network.

摘要： A method for processing a data packet at a node in a Bluetooth Mesh network, comprising: (a) determining a one-hop device cache list of the node, wherein the one-hop device cache list comprises an address of one or more one-hop nodes; (b) when the node sends a data packet, checking whether a destination address of the data packet is the same as an address stored in the one-hop device cache list; if yes, setting a TTL value of the data packet to 0 and sending the data packet; otherwise, setting the TTL value of the data packet to be greater than a specified TTL threshold, and sending the data packet; and (c) when the node forwards a data packet, checking whether the destination address of the data packet is the same as an address stored in the one-hop device cache list; if yes, setting the TTL value of the data packet to 1 and forwarding the data packet; otherwise, deducting the TTL value of the data packet by 1 and forwarding the data packet. According to the present disclosure, the problem of signal interference in a dense Bluetooth Mesh network may be significantly reduced.
