The invention relates to the technical field of
Bluetooth automatic networking, and discloses an automatic networking method for
Bluetooth networking, which comprises the following steps of: sending a
signal by a child node, scanning and filtering broadcast information by a root node or a father node, screening and connecting strong
signal nodes which have the same network ID and are not distributed, establishing a
timer, and automatically terminating a node network access process after
timeout. And sending a network access invitation packet to the node through the root node, replying a
verification network access request data packet by the node, when the root node verifies that the type of the data packet is correct, allocating a node ID to the new node, determining the new node as the child node, and after the child node receives the allocated node ID. The
tree network topology is formed through the three-level architecture of the root node, the father node and the child node, the root node overall manages the
global topology, the father node focuses on local child
network control, the child node only needs to maintain the own state, the calculation and storage overhead of each node is reduced, and the method is particularly suitable for a low-power-consumption equipment networking scene.
