Abstract

The invention discloses a SIG mesh-based broadcast bearer layer message filtering strategy method, the method is based on the bluetooth SIG mesh mesh network, and the mesh mesh network includes a bearer layer, a network layer, a transport layer and an access layer, The bearer layer transmits data between mesh nodes and passes it to the network layer, and the mesh node receives broadcast messages at the bearer layer, and compares them with preset queues to realize the mesh Filtering of broadcast packets in a mesh network reduces RAM consumption and CPU execution time. The invention optimizes the consumption of RAM, CPU execution time, and BLE scanning time due to the interference of non-mesh broadcast packets in the air, and optimizes the consumption of RAM and CPU execution time caused by repeated data packets.

Description

technical field

[0001] The invention relates to the technical field of bluetooth SIG mesh, in particular to a method of broadcasting bearer layer message filtering strategy based on SIG mesh. Background technique

[0002] At present, more and more devices are networked through Bluetooth mesh, and the network scale is also increasing. A family may also have hundreds of mesh nodes, such as smart lights, smart sockets, smart fans, etc. However, in order to stably control the operation of the equipment, each manufacturer sends the same data packet repeatedly. The light sends about 10 identical data packets, and these 10 packets will be forwarded and diffused by other devices in the room, which will cause a lot of data packets in the air. For Microcontroller Unit, MCU), receiving and processing these data packets is a very heavy burden.

[0003] At present, many Bluetooth chips are low-speed microprocessor chips. If the mesh nodes developed by these chips receive Bluetooth broa...
