Embodiment 1

[0041] A bluetooth mesh low-power node and its network system, including the low-power node, a first partner node, and a second partner node, and the low-power node establishes a partnership with the first partner node and the second partner node.

[0042] The low power consumption node includes a processor, a memory, and a software program stored in the memory and executable by the processor, and the processor can perform the following when executing the software program:

[0043] Step 1, the low power consumption node establishes a partnership with the first partner node and the second partner node, such as figure 2 Shown:

[0044] a1) The low-power node broadcasts a partnership establishment request for the first time, and establishes a partnership with the first partner node that first returns a relationship establishment response, ignoring the relationship establishment response received later;

[0045] a2) The low power consumption node broadcasts a partnership establi...

Embodiment 2

[0062] Compared with Embodiment 1, Embodiment 2 differs in that the low-power node sends the network address of the second partner node to the first partner node. When sending the request data packet, the network address of the target node in the request data packet is The network address of the second partner node can also achieve the effect of reducing the packet loss rate.

Embodiment 3

[0064] The difference between the third embodiment and the first embodiment is that the low power consumption node not only establishes a partnership with the first partner node and the second partner node, but also establishes a partnership with other partner nodes, and sends the first A network address of a partner node, the more the number of partner nodes to establish a relationship, the lower the packet loss rate.

Abstract

The invention discloses a data interaction method between a bluetooth mesh low-power node and a partner node. The low-power node establishes a partnership relationship with at least two partner nodes; the low-power node sends the network address of the first partner node to the second The partner node, or send the network address of the second partner node to the first partner node; the low-power node sends a request packet after waking up, and the request packet contains the network address of the target node, and the target node is the first partner node or the second partner node; the low power consumption node receives the data packet returned by any partner node, and the data packet is pre-buffered in the first partner node and the second partner node. The present invention can greatly reduce the packet loss rate in the process of data interaction between the low power consumption node and the partner node without increasing the hardware cost, thereby further reducing the power loss of the low power consumption node and improving the service life of the low power consumption node.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a data interaction method between a bluetooth mesh low power consumption node and a partner node. Background technique [0002] There are two ways to optimize the power consumption of existing Bluetooth mesh low-power nodes: one is to modify the wake-up interval of low-power nodes, which can be woken up by a timer or dynamically adjusted based on user habits; the other is to Increase the wake-up method and optimize it from active wake-up to passive wake-up, at the cost of increasing hardware costs. Although these two methods reduce energy loss to varying degrees, the problem of retransmission caused by packet loss in wireless communication has not been solved. [0003] In the Bluetooth mesh network, there are more than one partner nodes around the low-power node in most cases, but usually the low-power node will only establish a partnership with one of the partner n...
