Embodiment 1

[0073] Embodiment 1 of the present invention provides a data transmission method based on a Bluetooth MESH network. The schematic flow diagram of the method can be found in figure 1 . The subject of execution of the method may be the host stack or any node in the Bluetooth MESH network, etc., and the host stack is taken as an example for illustration below.

[0074] The method may include the steps of:

[0075] Step 101, acquire the current queue depths corresponding to at least one ADV transmission data packet currently included in the queue.

[0076] Among them, some of the ADV transmission data packets currently included in the queue may be the first transmission, and some may be the retransmission. The queue depths corresponding to the first transmission and retransmission may be different. Therefore, the queue depths corresponding to at least one ADV transmission data packet currently included in the queue can be obtained according to the following method:

Embodiment 2

[0123] Embodiment 2 of the present invention provides a data transmission device based on a Bluetooth MESH network. The structural diagram of the device can be found in Figure 4 , where the device includes:

[0124] An acquisition module 301, configured to acquire the queue depths currently corresponding to at least one ADV transmission data packet currently included in the queue;

[0125] The obtaining module 301 is also used to obtain the queue depth currently corresponding to the ADV transmission data packet to be inserted into the queue;

[0126] A determining module 302, configured to determine the sum of at least one ADV transmission data packet currently included in the queue and the first quantity of data to be inserted into the queue;

[0127] The determination module 302 is further configured to determine, among the first ADV transmission data packets to be screened, a first target ADV transmission data packet corresponding to a queue depth less than the sum of the...

Abstract

The invention discloses a data transmission method and a device based on a Bluetooth MESH network, in this invention, the queue depth limits the number of ADV transmission packets in a queue. The number of ADV transmission packets in a queue cannot be greater than the minimum queue depth in the queue corresponding to the current ADV transmission packets in the queue. This is conducive to alleviating data storms and queue congestion and maximizing transmission speed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method and device based on a Bluetooth MESH network. Background technique [0002] In the prior art, when performing data transmission in the Bluetooth MESH network, the data sender will send at least one ADV transmission data packet in the queue to the data receiver. [0003] Wherein, if there are many ADV transmission data packets in the queue, the ADV resources are limited, and the ADV transmission data packets are likely to be congested, resulting in a slow transmission speed. Contents of the invention [0004] The object of the present invention is to provide a data transmission method and device based on the Bluetooth MESH network, to solve the problem of relatively slow data transmission speed in the Bluetooth MESH network in the prior art. [0005] To achieve the above object, the technical solution of the present invention is: [0006] The ...
