The invention discloses an automatic configuration method of a Bluetooth mesh friendship function. The automatic configuration method comprises the steps that each low-power-consumption node periodically broadcasts friend request messages; a neighbor node receives the request message data packet and sends the information to a client; after receiving the message of the neighbor node, the client calculates the distance according to the signal intensity of the neighbor node; the client configures the neighbor nodes close to each other as candidate friend nodes according to the acquired distance information; each candidate friend node receives the friend request message sent by the low-power-consumption node and replies; and the low-power-consumption node selects a friend node from the candidate friend nodes according to the receiving window and the signal intensity. On the premise of ensuring the interaction reliability of the friendship function, the energy consumption of the low-power-consumption node is effectively reduced, so that the method is suitable for wider application scenes, and the application value of the Bluetooth mesh friendship function is further improved.
Description
technical field [0001] The invention belongs to the technical field of mesh network wireless communication, relates to the technicalization of a bluetooth mesh protocol stack, and in particular to an automatic configuration method of a bluetooth mesh friendship function. Background technique [0002] Bluetooth is a short-range wireless communication technology and one of the basic technologies of the Internet of Things. Bluetooth technology mainly includes classic Bluetooth and low-power Bluetooth technology. Bluetooth technology is widely used in many fields such as medical care, sports and fitness, security systems, and sensor Internet of Things. [0003] In order to solve the problems of short transmission distance and poor networking ability of Bluetooth technology, in July 2017, the Bluetooth SIG issued the first version of the Bluetooth mesh standard specification to achieve global interoperability of the mesh protocol. Mesh is a new network topology choice for low-po...
